Welcome to our current range & stock of 'Pre-Loved' Differentials.

                     If you don't see what you need or fancy - Ring 07879082490 !

1st are 4 Pins, then 'ATBs', followed by 'Auto Lockers', then 'Full Lockers' - Scroll down to what you fancy ( NOT in price order ! )

'Second Hand' 'Refurbished' 'Used' ... Whatever you want to call them ... we call ours 'Preloved' !

Whilst it would be lovely to have a lovely custom built, Brand New Ashlocker / Quaife etc, with a fabulous new Heavy Duty Crown Wheel and Pinion + Pegged Casing and so on we know not everyone can either afford or sometimes even justify the costs. We know this - So, whenever possible we like to offer a selection of our 'Pre Loved' Differentials.

These all go through our workshops and are all 100% stripped to the smallest component parts, cleaned, inspected and are then rebuilt to the highest standards we can achieve. Our 'Ultra Build Specification'is the same as all our new Differentials.
We have had customers comment on arrival the differential even looked like new - and that's why we are happy to put our name on them.

We do the very best we can on all our Pre Loved Differentials.

Yes they are 'Used' 'Secondhand', whatever your want to call them, but these offer a significant cost saving and give customers the opportunity to upgrade which might otherwise be outside their budget, and our 'Pre-Loved' Differentials are built to an exceptionally high standard.

In the listings you will often see comments relating to whats been replaced, and their regarding pictures these are not daft 'Stock' ones - the pictures are of the actual differentials in the listing !

The Differentials listed below are NOT in price order. Stock is subject to rapid change - what you see today can be gone in a flash - and when it's gone ...it's gone !.

Pre Loved 24 Spline KAM 4 Pin Long Nose Differential + 'Forged Cross Shaft' with 3.54 Ratio CWP. Ref 24KAM16

A Lovely KAM Differentials '4 Pin' 24 spline differential. Known for being way 'OTT' in terms of build strength - just look at both the number of bolts used AND the thickness of the end flanges !. These are strong - really really strong !.

Internally the OTT strength build shows - a 1 Piece Forged Cross Shaft was and is STANDARD !

Still probably the strongest 4 pin unit out there, this is a full Ultra Build Spec, all new Timken Bearings, New Puma Drive flange upgrade, New Genuine seal, then our Superflange upgrade.

This has all been rebuilt into a very late 'PUMA' Colletted Casing, which we have then further upgraded with our Domex 700MC carrier cap conversion.
This rids the casing of its 'achilles heel' - namely the standard factory hollow 3mm roll pin trying hard to hold it all together and not blow up, and them added our own HD Locking adjuster ring 'Ears' made from CS80 and bolted in place.

Basically a very very very nice seriously seriously strong 4 Pin 3.54 ratio differential thats not going to break your bank too much ! .

NO Exchange unit and No Surcharges etc required.

Pre Loved 24 Spline Genuine LR V8 90 4 Pin + 'Forged Cross Shaft' 3.54 CWP. Ref Military4PIN

These brilliant 4 pin centers are now getting quite rare.
These centers were fitted by land Rover to the rear axles of the Military supplied 90s that carried either radio gear or munitions, where a much much stronger center was required over the weak 2 pin units.

For once LR got these spot on and they crossed over for a short time and were used in the rear axle (only the rear) of the Land Rover V8 90s. And here is one of these lovely units in beautiful condition ready to go again. Its been completely stripped cleaned repolished rebuilt, ready for its new home.

These are well know as great units, amazingly LR for once got these spot on - but - these proved not cheap to build, so LR did limit what they put them in !
Amazingly - These have a factory 'one piece forged cross shaft' fitted as STANDARD !...so these are really strong, - really really strong !.
This is a full Ultra Build Spec, all new Timken Bearings, New Puma Drive flange upgrade, New Genuine Pinion Seal, and then our Superflange upgrade.

All then rebuilt into a very late 'PUMA' Colletted Casing, further upgraded with our Domex 700MC carrier cap conversion. A Cracking budget HD 4 Pin Unit !!.
The Domex Carrier Cap upgrade rids the pegged casing of its 'achilles heel' - namely the standard factory hollow 3mm roll pin trying hard to hold it all together and not blow up, and them added our own HD Locking adjuster ring 'Ears' made from CS80 and bolted in place. This diff center deserves to be in a special Build !!

Basically a very very very nice 4 Pin Standard 3.54 ratio differential - we would love to find more - but sadly often (unlike this one) they haven't been looked after.
We really love these units - these prove brilliant for upgrading a daily driver with a strong upgrade - Front or Rear fitment. Grab it whilst you can.

NO Exchange unit and No Surcharges etc required.

Pre Loved 'Rather Special' 24 Spline HD 4 Pin + 'Forged Cross Shaft' with New Genuine Land Rover 3.54 CWP

These were originally made for the military as a serious HD Long Nose 3.54 4 Pin Unit, which is here with its Brand New Genuine Land Rover 'Ex Military New Old Stock Crown Wheel and Pinion', with a further upgraded 4 pin center - read on - and there is even a video to watch !! (At the moment the video is of this actual Differential ! ).

This unit post dates the earlier Long Nose Military 4 pins (which were really really good units) - those had a strong 16mm forged cross shaft in the center - these have a 18mm forged cross shaft, (we have never ever seen one of these forged one piece cross shafts break !).

This center has been fully rebuilt and upgraded further with our 'Tablock' system on the Crown Wheel bolts and finally, when all finished this is what you see here..... This is some 4 pin !!

Its been completely stripped cleaned repolished rebuilt, and is all now ready for its new home. Here is the video : Click to watch video

This is a full 'Ultra Build' Spec, all new Timken Bearings, New Puma Drive Flange upgrade, New Genuine Pinion Seal, and then our Superflange upgrade.
All then rebuilt into a AquaBlast cleaned and refurbished Casing, we have added our own HD Locking adjuster ring 'Ears' made from CS80 and bolted them in place.

Basically a very very very nice seriously HD 4 Pin Standard 3.54 ratio differential - and we will be building a few more as we really love these units.
Brilliant for upgrading a daily driver / green laner with a super strong very high spec and really excellent value for money 4 Pin upgrade - Front or Rear fitment. Grab one whilst you can.

NO Exchange unit and No Surcharges etc required.

New Ashcroft 4 Pin Tablocked Center + PL HD 3.5 Rear CWP + Pegged Casing + Forged Cross Shaft. Ref PL4PINFCSPL3.5D

This is a very seriously strong Multi Upgraded 4 Pin Differential, with possibly a very small problem - which, depending on its new purpose may well not be a issue !

This is because it has a small 'Blemish' (see Pic 5) on the Pinion. Possibly a Manufactuering mark, but we have done what we can, and its still there. !!.
The likleyhood of this mark could be a small 'Ticking' noise when being driven - and hence why it might be a issue - So read on !

This is a Pre Loved Heavy Duty Rear Ashcroft 3.5 Crown Wheel and Pinion gearset, and, with these huge teeth - even when brand new - they can bit a bit noisey, this just may be a bit more so... , Sooooooo...if you have a very late PUMA TCDi etc with lots of sound proofing, road tyres and is you daily driver..... we would suggest (even though the price is seriously attractive) you give this a miss !

However, if you wnat a really stong 4 Pin diff, and the planned use is for maybe a racer, or a Trailer, or even say a 4x4 for a bit of 'on road' and maybe more 'off road' 'playday' / 'greenlaning' use, with a 200 / 300 / TD5 diesel etc ....oh and some mud tyres - this could be JUST up your street !.

Make no mistake - THIS is a serious diff, really really serious diff massively strong and for a very keen price.
The 'Mark' makes no difference to its strength, and having looked and 'erred' and 'arhhed' we decided to do the very best we could to get it as it is now..and its serious !

The Upgrades are - A Aqua Blast Cleaned and refreshed new Late 'Colletted' Metric Pegged Casing to which we have added our 'Domex Carrier Cap Conversion', a brand new Ashcroft 4 pin center has been upgraded with our 'Tablock' Upgrade and further beefed up with the addition of one of our special internal One Piece 'Forged Cross Shaft' units, and THEN ....all with a Full Ultra Build Spec, with all new Timken bearings, Genuine Pinion Seal, all new and upgraded Bolts + Nordlocks, Puma Drive Flange upgrade, and our Superflange upgrade to finish it off !

You want something strong ? - This is massively strong ! - All in all this is a seriously upgraded 4 Pin Differential, which won't break the bank and saves a fortune over new !.

Price, as with all our Differentials is a OUTRIGHT Cost - ie NO Surcharges, NO Exchange Costs.

New 24 Spline Ashcroft 4 Pin in Pegged Casing with Domex Carrier Cap Upgrade and 3.54 Crown Wheel and Pinion. Ref ASH4PINSTD-1

Hmmm - the Land Rover you have really needs a nice new differential, and as in this case here - this qualifies as good for either a front or rear fitment.

You don't want a 'Locker', nor an ATB' - you just want a really nice new strong quality differential, preferably without breaking your bank too much, but in a Pegged casing to make it way stronger and protect your investment for a little more expenditure........

So here maybe is possibly what you are looking for ?.....Nice specification - definately stronger than the rather useless standard diffs - but not bonkers on specification or costs ?

Here we have a Brand New Ashcroft '4 Pin' centre....Way way way stronger than the normal '2 Pin' standard LR fitment

This is our normal Full Ultra Build spec, Rebuilt into a very late and very low mileage 'Puma' Casing with its 3.54 CWP, and with our Domex Carrier Cap and HD Locking Ear conversion, finished off nicely with the fitting of a New Puma round drive flange.

Its madness having something that spins around at high speed thats square ? - round is better - Ah yes, but Square ones are cheaper...
Puma Round ones we use are a little more expensive but so much betetr - so here we have a Puma ROUND drive flange + our Superflange upgrade + all built up lovely unit - ready to fit

Whilst this might be one of our less expensive diffs the standard of build is the same as if our top end builds.
If you look at the pictures for example - the new Crown wheel bolts are genuine Land Rover military 'Wolf' bolts - HD Flange head 12.9 Grade, the Carrier Caps bolts are all new and also 12.9 Grade with special 'Nordlock' (expensive but the best out there) washers - and so on.

Nice, simple, good value, 'kin' strong - Oh.... and a really nice example, without going over board on either specification or costs.
No Exchange unit and No Surcharges etc required this is an outright purchase price.

PreLoved PUMA 110 4 Pin SHORT NOSE Forged Cross Shaft DANA 3.54 Domex. Ref 1104PINDOMFCS-2

These are the other type of Land Rover Differentials fitted to Later 110 Reer Axles - - Known as 'P38 Diffs', 'Wolf Diffs' or just plain 'Short Nose Diffs'.
These cause all sorts of issues - and failures as they are not - in anyway shape or form - a Decent replacement for the Older 'Salisbury' Axle which was previously fitted to 110 rear axles.

In Standard from frankly they are pretty poor, we have specnt considerable time working out a series of routes to make these massively stronger - this has some but not all of them !.
To understand better, rather than 'a picture tells a thousnad words', try watching this video !
Everything that can and does go wrong on a standard 110 Short Nose differential unit - and our Upgrades

We rebuild many of these now, along with some or all of our upgrades both in 'Pegged' and 'UnPegged' Casings, this unit is 'Unpegged'.
BUT ....as mentioned we have removed many of the main failure points of these units. Frankly we feel we don't want to supply customer with these units without the 'Domex Carrier Cap upgrade' etc, as we thing they would be wasting their money - so whilst (like with this differential spec) we try to keep the final costs down, there are some things we belive are just too risky to leave 'as is' and risk the unit failing.

At the end of the day these are going in a 3.5 Tonne tow capability 110 or 130, and having just a hollow pin each side of the diff holding it all together is in our opinion just not something we will put our names to .So, this does not now have the daft silly and weak 3mm Hollow roll pin which (often fails) holding the entire differential together - it has been Upgraded with our Domex 700MC 'Carrier Cap Conversion' with our own HD CS80 Grade 'locking ears' - Massively stronger. This roll pin nonsense was purely a 'Cost Saving' idiotic idea from LR

2nd, the 2 x internal crossover shafts which break (each having 50% cut out at the center where they cross so no it does not have 2 x 18mm cross shafts, it has 2 x 18mm cross shafts with a huge 'notch' out of both.... so its 18mm x 9mm ..... !!) so these have been binned and one of our monster strong one piece forged cross shafts has been added - never ever have we seen one broken.... in 15 years...

And 3rd - we have upgraded all the bolts, from the Crown Wheel to the Carrier Caps, and even the Pinion itself has a stonger grade 10.9 Grade Flange Headed Bolt.

All in all this makes this unit hugely stronger, then on top of all of this ( 4th !) the casing is also one of the very late types which has locking collets between the case and the caps, and as you can see from the Blue Check, this has turned out to be an absolutely beauty, so both stronger and super quiet Mid Range of Upgrades we can do, a balance of price vs strength. Much less than this on these unit is frankly just a huge risk of wasting your money.

A 'NO Exchange' Purchase is possible, see 1st Option, but if you have a core unit to exchange we will ship and then refund on reciept of an acceptable unit, Exchange unit doesn't mean 100% working and perfect - ring to discuss. We will also consider taking a P38 2 pin unit in P/Ex (for not as much though LOL )

Pre Loved 24 Spline PUMA 110 Ultimate 4 Pin SHORT NOSE Differential - 'The Strongest we can build'

These are the other type of Land Rover Differentials - Know as 'P38 Diffs', 'Wolf Diffs' or just plain 'Short Nose Diffs'.
Fitted to Late TD5 110 and 130s Rear axles (Standard 'Long Nose' type diffs in the Front Axles), P38 Range Rovers Front and Rear and Wolf Military Land Rovers.

We have an "Ideas" list .......some ideas are bonkers....... and after more sane thought they get either modified or dropped,....... and those we think are a really good ideas can take an age to actually / ever get to the top of the list to get developed ....and done.

We had a Project to sort out these via a series of upgrades to then be able to offer customers a way superior replacement 4 Pin 110 Rear Differential, and here we are project completed, with 4 MAJOR strength upgrades to choose from.

The Land Rover 110 4 Pin Rear Differential 'Multiple Strength Upgrade Project' was born. Since then we have sold a number these, some as in this one being 'Top of the Range with Everything', to others with just some of our various optional upgrades (you may find some of those listed here dependent on stock).

But ..this ....THIS Differential has EVERY Optional Strength Upgrade we can do to make this the strongest unit you can buy
Just what were LR doing when they launched this differential in its standard form as a replacement for the Salisbury ? ...

In its standard form it's just not a great Diff at all. Now that they have been out and about for a while they are showing up all sorts of design issues and failures.

We have a video done on Prototype No 1 (long since sold ....and doing well ! ), which shows the various design issues, and our upgrades and fixes of the 110 Short Nose 4 pin Differential and covers the FOUR upgrades we can now offer to make this Differential so much stronger - oh - and this unit here has all four of our upgrades !

1. Our Pegged Casing - 2. Change the 2 x weak 'cross over' center shafts for our 'One Piece Forged Cross Shafts' - 3. Upgrade with our Tablock upgrade, and - 4. Our Domex Carrier Cap upgrade conversion.

The differential itself has had the center completely stripped ultrasonically cleaned and all repolished and rebuilt, (Plus Forged Cross shaft as in pcture !), all new Timken bearings, Genuine seal, New Genuine Drive Flange, Upgraded 'Carrier Cap' Bolts with 'Norlock' washers, and the best new 3.54 Standard Ratio Crownwheel and Pinion made - Namely a New Dana (Made in USA)

Click to watch video - It's a stunning differential !.

A 'NO Exchange' Purchase is possible, see 1st Option, or with an exchange - Oh, and 'Exchange' unit doesn't mean 100% working and perfect - Ring to discuss.

We will also consider taking a P38 2 pin unit(s) in P/Ex (- Ring and lets have a chat

Everything that can and does go wrong on a standard 110 Short Nose differential unit - and our Upgrades

We rebuild many of these now, this now is pretty much where we start as a sensible build, anything less is basically just a waste of the customers money, as its just not strong enough. The Forged cross shaft and the Domex Carrier cap upgrade superflange and ultrabuild make this a great differential to buy and replace.

The next step(s) up are either a pegged casing and / or a Locker of ATB or even a further upgraded 4 pin center, but this unit offers a good balance between having serious strength upgrades balanced with a lower price tag than going for everything.

If However you plan to do a lot of towing then we would seriously suggest you find or ask us for one with a Pegged Casing Upgrade

BUT ....as mentioned we have removed many of the main failure points of these units. Frankly we feel we don't want to supply customer with these units without the 'Domex Carrier Cap upgrade' etc, as we thing they would be wasting their money - so whilst (like with this differential spec) we try to keep the final costs down, there are some things we belive are just too risky to leave 'as is' and risk the unit failing.

Pre Loved Ashcroft 24 Spline AATB + Pegged Casing + 3.54 Standard Ratio.

Have a lookie at the 'A-Z of Land Rover Differentials section regarding what an 'AATB' is if you are unsure.

In simple terms on an 'Open' Differential driving on wet roads, sand, snow, mud, or even wet grass, one wheel typically breaks traction allowing all the drive to the wheel which then spins, loosing traction, and shortly after - you are stationary !.

Additionally standard 2 pin differentials are desperately weak and fragile and break so easily. These ATBs are very very strong..... along with a massive jump in traction.

Sooooooo....this differential ..... !

This was P/Ex by a customer towards a set of Pre Loved Lockers. Now this unit is well known to us, we have rebuilt this twice, and it has been well looked after, but it is 'Of an Age' now.

We have completely stripped it down - and I mean completely, to give it the very best rebuild we could.

The casing has been AquaBlast (re)Cleaned and then repainted, the AATB center itself has been completely taken apart and then all internals cleaned and repolished and then rebuilt with all New Timken Bearings, along with its original Crown Wheel and Pinion - which has been ultra soncially cleaned and then all assembled with all new HD Bolts, Nordlocks, Drive Flange, Genuine seal, basically as w do with all our diffs

So, whats the catch ?

Well, there isn't one really, this is just as it looks a nicely well used well cared for rebuilt Differntial, which, having the CWP reset with new bearings means its not as 'silent' as a new one would be. So, if you are thinking of this for your very late 'ultra well sound proofed' PUMA 90 etc, then Noo, maybe not for you it might just be that bit noisier than you might like, but, if you have 90 / Disco / 200 300 TD5 etc on INSA turbos and the diesel rattling in the background with the tyres, used now and again for greenlanning and playdays / hack type truck - PERFECT !

It's still had our full 'Ultra Build' spec as mentioned above, with our Superflange upgrade, upgraded Crown Wheel Bolts with special Nordlock Washers, Puma Flange upgrade, and it's all ready to fit to either your front or rear axle.

Now, a warning ....If this is your 1st ATB - then the rear is the axle to fit it too...but ...there is a major down side with these .....
Many many customers buy 'Just the one thanks Nige' and then, having fitted one to the rear, and being stunned by the additional grip traction and general feeling of it just behaving safer, and the improved handling on and off road with the grip and traction these give ....end up coming back for a front lol ...you have been warned !

ATBs are HUGELY underestimated, better traction better grip really these can and do transform your LRs drivability ....and they are very very strong units.

And this one, well,............. that is a lot of differential for the money !

If in any doubt ring and chat - NO Exchange unit and No Surcharges etc required this is an outright purchase price.

A very very VERY Special AATB/LSD Differential - Miss this and kick yourself - you'll never see another !

Way way back, in around 2007/8 Dave at Ashcroft Transmissions was designing a new and rather special A-ATB Differential.
There was an initial production run, then the project was shelved as the Ashlocker was deemed to be a better bet to market.

This new products production was shelved, the few made put on a shelf to be forgotten about .Move forwards to 2025, and after chatting the story of these popped up.
I bought a number from Dave, which were near instantly sold, and then this one was built up for a friend to conduct a longer term test.
Dave meantime decided to reconsider relaunching and looked into the possibility of a limited production run.

After some time it was decided that whilst this was a great new product the capital outlay just wasn't there. Other products and investment into them were higher on his list.

We know this ourselves, we design and make new products, some make it to market, and some don't, some don't even mnake it off the Solidworks stage, others like this we might make a few batches.
With this AATB + LSD Differential.. this... along with the initial batch made into production - we can now confirm sadly no more will be made ........

What you are looking at then here is very much the last of these you will probably ever see for sale. Those who bought the stock we had have all reported back that these are quite amazing !

So, what is it - why is it so special, and how does it differ to say the Quaife ATB and Ashcrofts own AATB units ?....
Easiest to watch the launch video we did, which is showing below, this explains what is it and why it is so good !

An amazing Ashcroft AATB + LSD Combination Differential

You even get the full strip down and rebuild video with this diff !!

Now that I have managed to finally after much asking (didn't want to hand it back lol) extract this diff back from my friend, we have stripped it completely, checked the internals and it is like brand new.
A (Re)Build video will be loaded in here shortly (If it's not sold before !).

It is going to be rebuilt - as it was when 1st built - with its 3.75 Rear HD gearset - (you do NOT put this in a front axle !!), full 'ultra spec' build, and it will have all new HD Bolts and Nordlock NLX washers, new Pinion Drive Flange, new Genuine Seal, New Superflange, New Rear Oil Vane Upgrade, and the Pegged Casing has been re-cleaned and repainted.

If we hadn't told you it was not all brand new you would never have known - its that good ! and as a Differential - It's in a league of its own !!!!!
Oh, and if you fancy it and you wait too long, once this has gone - don't ask - you will not see another - this is the very last of the batch !.

Pre Loved Ashcroft AATB 24 spline + Brand New HD Antonio Maserio Standard Ratio 3.54 Crown Wheel and Pinion

Here is a Pre Loved Ashcroft AATB. (Customer changed for a new full blown Air Locker).
We took this in P/Ex and now its all built up with a lovely brand new 'Antonio Maserio' Crown Wheel and Pinion, in the standard 3.54:1 Ratio.
This being the case its good for either front or rear fitment. If this is required for a Discovery 2 Rear Axle we can change the Drive flange for the special D2 one at no extra cost.

The Center has been completely stripped cleaned and gears all repolished, its then been completely rebuilt into a late refurbished Standard PUMA Colletted casing + of course we have upgraded the daft silly weak pins that supposedly hold it all together with our Domex Carrier Cap Conversion and Locking ears.

Being our normal full 'Ultra Build' spec, its assembled with all new Timken bearings, our 'Superflange' upgrade, and a Round late 'PUMA' drive flange vs cheap nasty square one.....
(WHY would you want to fit something that spins at high speed off road - and have it SQUARE ???... Oh yes of course becuase it's a few quid cheaper (facepalm) ....So a Round PUMA one it is then ).

A Lovely Differential, have a lookie at the picture showing the rear face of the Crown Wheel - shows off the quality of its fabulous new Crown Wheel and Pinion - will be quiet and a great Upgrade for any LR

NO Exchange unit and No Surcharges etc required this is an outright purchase price.

New Ashcroft AATB + Ashcroft Pre Loved 4.75 Front Cut CWP + PUMA Casing with Domex Carrier Cap Upgrade Ref ATBPL475FC

At 1st glance you might say 'Isn't this brand new ??...' Yes it looks it but its not quite.
The Pegged Casing & ATB and all internals are new with the exception of the HD Ashcroft Crown Wheel and Pinion.

This was taken in P/ex from a customer who had been poorly advised in what Ratio change he needed, it didn't take him long to cotton on either !. So, its done hardly any miles as you can see, and we sent him much much happier with new 3.75s !.

So, here it is - its virtually brand new, looks brand new, has all the upgrades, all new bolts,Genuine pinion seal, Puma Drive flange, Superflange, and being that this is for front fitment - a front Oil Vane upgrade. Fully built back up to our Ultra Spec grade, into a 'Colletted' Late Puma Pegged Casing and with our Domex Carrier Cap to finish off a stunning ATB

Quite a saving over a new version of this, so grab a bargain. If we hadn't told you it was not all brand new you would never have known - its that good !

Pre Loved Detriot 10 spline Auto Locking Differential plus LAND ROVER 4.7 Ratio CWP. DETIMPCASE47

Here we have a really nice low mileage (been in storage for years) Detriot 10 spline 'AutoLocker'.

This has been stripped and rebuilt into a Split Nose Series Casing (fits Series 1 2s or 3s) with a 4.7:1 Ratio CWP (Standard Series Ratio)

We have kept everything on the outside that is 'Visible' Original with new lock tabs etc even repolished original bolts + new dust sheild and new drive flange and seal etc, but on the inside we have upgraded the CWP Bolts to FTC5150 12.9 Grade for more strength being it's now a Detriot !.

We have also upgraded the Carrier cap bolts again with 12.9 Grade bolts and Nordlock washers - again for additional strength - Detriot do Grip you know !!

Rarely do we get these units in this sort of condition, a really nice unit for not a huge amount of £s

Pre Loved Detriot Auto Locker 24 spline Differential with 3.54 Ratio Crown Wheel and Pinion in a Metric Casing. DET24SP354-2

Yes, as we call them - he 'Marmite' Differential. You either Love em ....or Loathe em...LOL.
However, if you know about these - they are as tough as they come, and nothing weirder in the way they work (See A-Z of Land Rover Diffs on this website to understand fully how these work !)

But, if you know what they are and you love them, then here it is in all it's weird glory.

YOU CAN ONLY fit these in a Rear axle - NEVER EVER EVER fit these in a front axle !.
This unit has had a complete and Full Ultra Spec Build, new Puma Drive flange and our Superflange upgrade. + Rear Oil Vane upgreade too.

It has been rebuilt with a Late Puma Colletted Casing, and does not have our Domex Carrier Cap Upgrade as it was built for a customer to his exacting spec - and when all finished he decided to go for and ATB with us instead !. So, if you would like it to have our Domex Carrier Cap Upgrade added - we can do this for the special extra of £55 Plus VAT ! (Normally £98)

this is NOT pegged really to help to keep the costs down.

A hell of a unit offering a absolute massive increase in traction and strength for money that won't break the bank.

Pre Loved Detriot Auto Locker 24 spline Differential + 3.54 Ratio CWP + Metric Casing. Ref DETRIOT24354-1

Yes, as we call them - he 'Marmite' Differential. You either Love or Loathe.
However, if you know about these - they are as tough as they come, and nothing weirder in the way they work (See A-Z of Land Rover Diffs on this website to understand fully how these work !)

But, if you know what they are and you love them, then here it is in all it's weird glory.

YOU CAN ONLY fit these in a Rear axle - NEVER EVER EVER fit these in a front axle !. This unit has had a complete and Full Ultra Spec Build, new Puma Drive flange and our Superflange upgrade. + Rear Oil Vane upgreade too.

It has been rebuilt with a Early Metric casing which is one of the strongest as it needs to really have a case up to the strength a Detriot jusifies, we have not gone as far as pegging it to keep the costs down , and is as quiet as a mouse walking on tip toes, - that is until the Detriot centre 'works' and then you will hear the noises only a Detriot can make 'Unlocking' ... and 'Re-locking' !.

A hell of a unit offering a absolute massive increase in traction and strength for money that won't break the bank.

Pre Loved Nissan Patrol Y61 Rear HF RD135 Locking Differential 4.37 Ratio SN 24-Y61-1

We very very rarely get these in to resell, but here we have just the one.... A Rear Y61 Nissan Patrol differential, fitted with a 35/8 CWP set which means it's the 4.37 ratio.

Its been completely stripped down to conponent parts, then cleaned, repolished with all new NTN SKF bearings, new Genuine Nissan Pinion Drive flange seal, and, if you look closely - further upgraded with new HD Crown Wheel Bolts 12.9 Grade same with the Carrier Cap bolts - and then all of them with Nordlock Washers. Being a Genuine Nissan CWP the blue check is excellent !.

The 'Preloved' HF (an ARB Copy) 'Air Locker' has had a new Piston internally, and new O-Rings, and this differential is ready to go to it's new home.

The casing itself has been heavily cleaned, this showed that its had a hard life - there is significant pitting on the casing, but this is only a visual thing really.
The inside was and is perfect. Fitted with our Swivelly stainless steel push fit hose adapter it's all ready to go.

Its the only one we have, and we doubt we will see another for some considerable time. Just make sure this CWP Ratio of 4.37 is the one you want - there are several different ratios of these differentials !
Available with or without the additional new hose switchgear fittings soleniod etc, which if required is just an extra £30.

NO Exchange unit and No Surcharges etc required - this is an outright purchase

Pre Loved Ashlocker in Standard 'Domexed' Case with Standard 3.54 CWP

So.....You really fancy finally a Nice 'Locker' or maybe a second for the front ?.

You don't wnat to spend a fortune, and having thought about options, you really fancy a 'Ashlocker'
No doubt the Ashlocker is ( in our humble opinion ) the best locker out there for a Land Rover,but, as such they 'do rather' hold their prices !

This one is unusual, as price wise its rather a bargain.
We took in a number of 'Take Out' Puma Differentials, (all 2 pins) and the Crown Wheels were really good low mileage units, so we stipped cleaned repolished them.
These were then reuilt back into the cleaned refreshed and repainted casing with new Timken Bearings, All upgraded bolts New seal and Puma Flange, our superflange and then fitted with a fully stripped and fully rebuilt Pre Loved standard Ashlocker.

NO Pegged Casing...., NO Tablock upgrade...., NO HD crown wheel and Pinion...., just a Nice standard Late Puma Collectted Casing (but with our Domex Carrier Cap Upgrade) a Pre Loved repolished Standand 3.54 Ratio Crown Wheel and Pinion, all rebuilt ready to go.

If you have a 'Daftly Mapped TD5 on Big Tyres and do events etc, then this is not for you ! - you need more, ....much more ...and different !

But for a more standard Truck, on say near standard tyres looking to have a bit of green lanning and off road fun, this is a really good entry level good condition unit
We rarely get this sort of thing, .....but thought it would just make a nice affordable unit - so here it is !

Pre Loved ARB RD128 in Pegged 'Domexed' Case with Standard Dana 3.54 CWP

There are lockers.... and there are lockers.
For a Land Rover the best you can buy is an Ashlocker............

Ok, this being an ARB this may not be as good as an Ashlocker, but make no mistake - its still good, and, in this case this is really good condition

This is the current ARB - the RD128 which is the 24 spline version.
In really simple terms, if you want the best you buy an Ashlocker, we even do further upgrades for them, BUT, these fetch a premium both new and Pre Loved

If you really can't justify a new Ashlocker, or even the prices of our Pre Loved ones - then an 'ARB' is the next best answer.
Ok, they are not as desirable in the world of lockers as an Ashlocker, but this means that the good news is they are a bit better value for money - thats just honesty the way it is !

BUT, even so, these ARBs have 2 major 'Achilles Heels', both of which is why we have this up for sale.....

The Center tube - or 'bell' is one piece and its very prone to fracturing on the ring end that bolts to the crown wheel, and this is what happend here, it needed a new Center tube.
At that time the problem for the owner was this wa his daily driver - and none were avaiable off the shelf - so as time was of the absolute essence - customer P/exd this and bought a new unit.
Addiionally, when the 'bell' broke that also then destroyed the air pipe, (which can also be damaged easily).

The answer to both these 'achilles heels' have been fixed on this rebuild.

Obviously this has a brand new center tube, and also a brand new air coupler system, but the fix for the bell no longer shearing is we have this now rebuilt - but with a pegged casing.

The air pipe issue - that now has one of our Xcess4x4 RD128 'clamp kits' fitted, this means both of the issues these ARB can suffer from are no more.
Oh, also this has new internal piston, new thrust shims, and O Rings - all replaced, and now ....this is a lovely unit ready to go again !

As mentioned on other 'Preloved' builds in here - We took in a number of 'Take Out' Puma Differentials, (all 2 Pins) threw the centers away, kept the Casing and the Crown Wheels which were really good low mileage units.
We then stripped cleaned both and repolished the CWPS...and this unit is the hard sought after 'Dana' version - Made in the USA these are the best LR ever used.
So this is doubly nice now !

This RD128 ARB is now all rebuilt with its Pegged Casing (and Domex upgraded too as its a late Puma casing) plus with new Timken Bearings, all upgraded bolts, New seal and Puma Flange, and our Superflange upgrade - and of course the Dana 3.54 Standard Ratio CWP, its all now ready to go.

It's a really good example of an ARB RD128 Locker, with the new Air Pipe and Centre tube even better with all our Upgrades , and a lot less than an equivalent Ashlocker.

Its very much 'You pays your money ....and you takes your choice'.

ARB RD56 + Upgraded Xcess4x4 End flange + 3.54 CWP in Puma colletted 'Domexed' Casing. Ref RD56_NO11

The ARB RD56 24 Spline Locker is actually nowdays quite old Locker wise, but it's actually one of our favourites.
The problem is that often, being old, they have been neglected 'somewhere' in their ownership - and - as a result they are either worn out, damaged or really in all honesty past their best.

This little unit is none of the above. It is in exceptional condition (see pictures of center pre-assembly) and was taken in P/ex for an upgrade.
Its been completely and utterly stripped (as you can see !!) ultrasonic cleaned and then rebuilt, with a New Internal Piston, new Drive Thrusts and other than the Air system O rings thats all that was needed.

It's done very little work and has also been properly looked after - as you can see from the dissasembly pictures, but, the end flange was worn (very common issue as its a weak casting) so it's had one of our EN34T CNC Billet RD56'End Flanges' we make popped on, now this is quite a unit.

Its been built into a very late 'PUMA' Colletted casing, (which we have also 'Domex Upgraded' the Carrier Caps), all New Timken Bearings, Upgraded HD Bolts and Nordlocks, and a nice standard 3.54 CWP with a New Genuine Pinion Seal, Puma Drive flange plus our Superflange upgrade to finish it off.

Its not often we get a unit such as this that is in such good condition, now all rebuilt this really does give someone the chance to enter the world of 'Land Rover Lockers' without a huge outlay.
To be honest we see these come up on Ebay for daft (expensive money) and just from looking we can see they are basically end of life junkers, this is in a different league, but at an atractive price even so !

You will struggle to find as good as this for this price. We try to cover all Differential options, ranges and prices, even at the lower end of the price bracket it has to be good for us to put our name on to resell it.
This lovely little 24 Spline ARB RD56 defo is !. The Blue check is amazing - you could fit this in a Late daily driver and it would be silent.

It's just so good we've done photos to show off it's amazing condition and done multiple pictures for you - to show off both inside and out !

Available with or without the additional all new - Hose, Switchgear, all Fittings, Soleniod etc, which if required is just an extra £30

NO Exchange unit and No Surcharges etc required

ARB RD56 + Upgraded Xcess4x4 End flange + Ashcroft 3.54 CWP + Pegged Casing. Ref RD56XS354PC1

A nice little ARB RD56 Locker - but in a much higher 'Upgraded' version than possbly 'the Normal' spec you see these !

The 'Non Air' End flange on these is a weak cast plate - these fracture and / or the bearing can spin on the journal, a common issue. means it needs replacing !!
The problem then is this part is no longer available - But thats all ok, as we remake them on a 5 axis CNC out of a Billet of EN34T - you'll never break that !.

So this as you can see in the picture has been stripped, with all parts ultrasonic cleaned then repolished, then fully rebuilt with new internal ARB Center cage and Piston, new shims and 'O Rings' along with our Upgraded Xcess 4x4 EN34T End flange, and then our upgraded HD Centertube bolts.

The center has then been put into one of our Pegged Casings, along with an Ashcroft Transmission 3.54 (Standard Ratio) CWP, a full ultra Build Spec, all new Timken bearings, Puma Flange upgrade, and finished off with our Pinion seal Superflange upgrade.

A really good entry level Locker, but in a seriously upgraded version !

Available with or without the additional all new - Hose, Switchgear, all Fittings, Soleniod etc, which if required is just an extra £30

A PAIR of Pre Loved Lockers, Both ARB RD128s + 3.5 Front and Rear Cut HD 3.5 CWPs + Pegged Casings Buy either or BOTH

You really fancy and would really like to have a pair of good condition 'Highish Spec' Air Lockers.
Maybe you are running 30 - 33" tyres, you are happy with your gearing but you don't want to break the bank too badly.
You've been looking... but oh boy ..the outlay ... Well, read on - this might just be what you have been hunting for !

There are multiple issues and hurdles with buying second hand lockers too.

Not just how much do you spend, or what exactly do you buy, but also are you buying a load of trouble needing full rebuilds or even worse ?.
There really are some real bandits out there selling dreadful overpriced Lockers that might look cheap - but will prove to be anything but.
And you will have committed a significant load of your hard earned money getting them.... and that's a worry at the back of your mind...

Once you start really looking the cost of investment and the spec you fancy the build costs just seem to keep rising.
With the money your are now thinking of spending you might decide its a good idea to protect your investment further than just getting a locker, by going for a 'Pegged Casing' Upgrade, (and with ARBs RD128s that also a really good idea, as these units unpegged can easily break the Center top hat which is serious money)....

Already you are now thinking of 'Lockers' and 'Pegged Casings', and well, a 'Heavy Duty' Front and Rear Cut Crrown wheel and pinion would be nice too ......
And before you know it your 'Build Spec' means you could be looking at easily over £4000 for a pair ! ..... Yeek !

Well, as it says at the start these 2 x units are 'high end specs' for sure.

They are BOTH in 'Pegged Casings', BOTH have 'Heavy Duty' 3.5 Crown Wheels and Pinions - a Matched Front and Rear too, and the Current Model ARB (and the strongest version made) the RD128 24 spline model, and, here you can buy EITHER or BOTH, at quite saving, and, should you push the boat out and buy both and really treat yourself - it works out even cheaper still !.

1st up - The Front Unit - (See Top 3 Pictures, click on them to see them full size) - This is a Preloved ARB RD128 (The current Model 24 spline ARB).

Its been completely stripped, cleaned, and rebuilt with new ARB Genuine Air 'O' Rings and a new ARB Internal Air Piston, built into a new Pegged Casing, with a HD 3.5 Front Cut HD CWP.
The Build is our Full 'Ultra Spec' Build Specification, with all new Timken Bearings etc, and then finished off with a new Puma Drive flange upgrade, this one has a Front Oil Vane upgrade and of course our Superflange upgrade.

A lovely differential, again, either buy this on its own, or the as a pair and save a bit on overall costs !

2nd - The Rear Unit (See Bottom 5 Pictures, click on them to see them full size) - This is a also a Preloved ARB RD128 (The current Model 24 spline ARB).

Its been completely stripped, cleaned, and rebuilt with new ARB Genuine Air 'O' Rings and a new ARB Internal Air Piston, built into a new Pegged Casing, with a HD Polished 3.5 Rear Cut HD CWP.
Look closely at the pictures and you will see this also has a Brand New Genuine ARB Main Body center tube, and, to match the above a 3.5 Rear Cut CWP.

This too has also had the full Full 'Ultra Spec' Build treatment, with all new Timken Bearings, new Puma Drive flange upgrade, a Rear Oil Vane Upgrade and of course our very popular Superflange upgrade.

All in all another cracking differential. Buy this on its own, or buy both as a pair - and save on the overall costs !

Either Differential or Both Differentials are available with or without the additional Fitting kit(s) - The Kits will come with ...
All new - Hose, Switchgear, Fittings, Soleniod etc, which is just an extra £30 on either unit - buy BOTH Diffs and get BOTH kits for the £40.

NO Exchange unit and No Surcharges etc required.

A PAIR of Pre Loved Lockers, Tablocked Ashlocker 4.1 + ARB RD128 4.1 Both Pegged Casings - Buy either ...or both and save £s !

Well, this might be tempting if you have a 90 or Defender probably on 34 or 35" tyres and standard 3.54 Ratio diffs ... and ......being on 3.54s it is so over geared it drives horribly both on and off road as a result - want to sort it out and transform your truck ?.....

You have been thinking about sorting out the gearing, making it drive so much better with the right ratios, plus maybe going for some lockers too ???
But ....You also know it could also cost you a small fortune as you know you need upgrade BOTH differentials at the same time, ...............
Well........... these could be just what you are after then !.

This listing is for a PAIR of Pre Loved Lockers, and both are very serious builds ! You can buy EITHER or BOTH. If you do buy both it works out cheaper !.
