Complete Fully Converted 'Pegged Differential' Casing Assembly For Standard LONG NOSE Differentials

These heavily modified Land Rover Long Nose casings offer a massive increase in strength, (Watch the Technical Video in Video section for an explanation of how they work).

All of our Pegged Casing are done by ourselves in house, and have Modifications including 24mm of CNC Machined Steel plate specially TIG welded into place, milled, drilled and tapped M16. These holes then hold the supplied Dog Bolts and our special Phosphor Bronze Pad which supports the CW&P from flexing and seperating. We have had just three of these fail out of 772 (as at March 2021) sold where the Crownwheel was so overloaded it sheared the teeth off the base plate ! See Video as to how we make these and what goes into the conversion.

On the basis that nothing is unbreakable, this unit + a HD CW&P set properly built up is going to be as good as you can get in a Land Rover axle (maybe with the exception of further upgrading to the 'Big Bearing Pegged Casing listed bwlow) !. Available either Exchange or Outright with No Exchange.

Complete Fully Converted 'Early Big Bearing Pegged differential Casing' Assembly For Standard LONG NOSE Differentials

Our 'Standard' Pegged Differential Casings offer massive increases in strength - but, following a yard clearance we have some extremely early LR Casings (late 40s and very early 50s) , where the internal bearings are all significantly Bigger - and Bigger Bearings = Stronger Differentials. Click to watch Video of one of these !

As an example of just one of the internal bigger bearings - even with our 'Standard' Pegged Casings, LRs Pinion Bearings are quite small and still can be a early failure area. These very very early Casings have huge Pinion Bearings compared to ALL other LR Casings - see the picture to compare. Over the years LR have changed the design and metal composition of their Casings, and, in simple terms each 'later version' is inferior to the previous one(s).

Even with our 'Standard' Pegged Casings we will only use early 10 and 24 Spline Casings with the 'Locking Plates' into the adjuster rings, they are hard enough to keep stock of - but - we think they are the best to use for our 'Pegged Casings' - until now - these 'Ultimates' are in a different league.

There is (as always) one downside - these 'Ultimate' Pegged Casings WILL NOT HAVE A FLAT on the base to bolt anything to, other than that we can build with any LR Long Nose Center and any LR make of CWP / Ratio to these 'Ultimte' Pegged Casings. We have obtained enough Casings to decide to have their own special conversion plates CNC cut to enable us to convert them, the Casing in the picture was Prototype No 1 - where we made modified plates and a new Jig - just to make sure we could do it, and it worked. It was built with a HD Ashcroft CWP and a Hi Spec Ashlocker

We will not be selling these on their own, they are all reserved as upgrades for customers who wish, while we can, to offer a 'Ultimate' HD Pegged casing over and above our 'Standard' Unit. We will have stock by 1st Nov 19 - Ring to chat if you have questions

Complete Fully Converted 'Ultimate HD Pegged Differential' Casing Assembly For Standard LONG NOSE Differentials

These are the Strongest Pegged Casings available.

Anywhere.

Period.

We do not sell these on thier own, they are reserved for Builds and Rebuilds we do where customers are looking for the ultimate in terms of a Pegged Differential

It was an idea that had been bouncing around in our minds as a 'maybe' for some considrable time - it would when done provide customers with 'The Ultimate' in terms of strength in a LR Casing .
The idea of the "Ultimate" strongest Pegged Casing out there was fianlly achieved on 15th June 2021 and after months of Prototyping reached a finished new product which is now avaiable. !

Complete Fully Converted 'Pegged Differential' Casing Assembly - For Standard SHORT NOSE / P38 Differentials

These heavily modified Land Rover SHORT NOSE / P38 / TD5 Rear Axle type casings offer a massive increase in strength, (Watch the Technical Video in Video section for an explanation of how they work). With the Modifications 24mm of CNC Machined Steel plate is specially welded into place, milled, drilled and tapped M16. These holes then hold the supplied Dog Bolts and special Phosphor Bronze Pad which supports the CW&P from flexing and seperating. On the basis that nothing is unbreakable, this unit + a HD CW&P set properly built up is going to be as good as you can get in a Short Nose / P38 Land Rover axle !. Available either Exchange or Outright with No Exchange.

Complete HD Domex 700MC Removable Differential Pan Kit

Our HD Removable Differential Pans are a little different to the other offerings on the market for Land Rovers - being made predominately made from 'Domex 700MC' Steel.
In simple terms this stuff is super bloody tough - as in its approx 3 x stronger than normal mild steel plate ... bear this in mind as you read on ......

The only welding needed is to weld the base plate ring and the fillets onto the axle casing - everything else is done for you. (Watch our Video )
The Base Ring is 8mm Domex, the Pan Base Plate is 5mm, and the Pan Cover itself is 3mm - multiply all of these by x 3 and that would be the Equivalent thickness if they were in mild steel !.

We have made the filler hole HUGE so you can get oil in easier, and Kits come with 'Nordlock' Washers - these are both very expensive - and the best lock washers you can buy.

Bend dent or damage these covers ...and you will probably have bigger issues finding the fillings that have been knocked out of your teeth with whatever you have managed to do to yourself and your truck :O)

Genuine ARB Compressor Kit - Model CKSA12

This really is a fantastic kit from ARB which includes the Compressor, a superb 'Plug and Play' full wiring loom with both 'Switch' Plugs (for Front and / or Rear Lockers), an Air Locker solenoid plug-in contact, an in Line Fuse, mounting hardware, Air Pressure Switch, a reinforcing bracket, and all fittings including a On/Off Compressor switch - and it's super easy to install !.

This Unit will easily cope with 2 x Lockers without any issue, in fact on my own truck this runs my 2 x Ashlockers AND my 3 x Winch Freespool Units - faultlessly.
This is a Genuine ARB CKSA12 Model, beware the chinese copies everywhere, they are frankly are a waste of your money - when you see what's in this Kit and the price - it is really a bit of a bargain.

These can be bought of the webshop 2 ways.

The 1st is just as a simple single outright purchase - £120.
The 2nd way is with a small discount if bought with ANY differential purchased off the webshop at the same time at the lower price of £105.

*** NOTE: If you buy at the lower price and not with any our our Differentials.... your money will be instantly refunded :o) ***

Xcess 4x4 'Tab_Lock' Upgrades for Ashcroft Lockers + ARB RD03 and RD56 Lockers

Quck lesson on 'Steel Bolts' and 'Tensile Strength'. It's called 'The Glass Bolt Paradox' ... and it goes like this ....
Steel, has a tensile strength, higher grades means higher tensile strength. But, GLASS has a higher structural tensile strength than Steel. So why are bolts not made out of glass ?. Because they would shatter. Simples. (A full web page on this producwill be coming shortly)

Our Upgrade to Ashlockers - backed, approved, and supported by Dave @ Ashcroft, (we also do this for ARB RD03 and RD56) is we, machine 'End Flanges' of 'Ashlockers' / 'ARBs' adding 10 x Oval 'Bolt Lock Slots', then add 10 x special Xcess 4x4 'Tab_Locks' allowing a LOWER Grade 10.9 3/8 1.1/8 UNF CR6 Grade 'S' Bolt + special washers torqued up with Shear Plates now locking CWP Bolt heads in position, allowing some stretch via a slightly less brittle bolt, it can't undo, as all Bolts are now held in tension AND in shear.

These are £88 for the Ashlocker (Exchange), and £216 for ARB (Outright). We ONLY sell these on our Differential Builds as upgrades we do NOT sell as a DIY Kit

Brand New Xcess 4x4 Ultimate 4 Pin Center + Tab_Lock' Upgrade + 1 Piece Forged Cross Shaft

We do all sorts of upgrades to all sorts of differentials. This is a new offering we can supply which will give you the strongest 4 pin center unit available anywhere for a Land Rover.

The Ashcroft 4 pin is a strong unit with its 18mm cross shafts, but made even stronger with our upgrade of the 3 x cross shafts and center boss to a 1 piece forged cross shaft. In all the years we have had these, plus my years at KAM differentials- I have never EVER seen one of these broken !. On top of this we have also CNC machined our popular and super strong 'Tablock' upgrade in the casing. (If you are unsire what this add strength wise have a look at the tablock Menu tab.)

With this 4 Pin Center + its Forged Cross Shafts and Tablock upgrades, this is a very serious differential !.

We carry limited stocks of these - if it shows as 'Resereved' then we have stock, if not it will show 'out of stock'

This unit can be built to order in any Build spec you wish.

Fully Built up Ashlocker + 3.54 Ratio CWP into Megasquirt V8 Ltd NON-Pegged Casing - Ready to fit - Call us re Stock

The 'Ashlocker'. Quite simply if you are looking at buying yourself a new 'Locking Differential' for your Land Rover these are without question the best. Period.
Nothing in our opinion comes close in terms of Quality or Relaibility. Ok, we are approved Ashcroft Dealers so call us biased, but we still stand by our view on these units as the 'No 1" choice.

We rarely build these in this format, but can if you want. Spending this sort of money the vast majority of customers ask us to build them 'Pegged'. Pegging adds massive strength to the finished unit and helps protect your £s investment. All our Units, New or Refurbished are built 'Up to a Specification' not 'Down to a Price'. We use the very best of everything we can and it's called our 'Ultra Build' Specification. A mix of new Genuine LR Parts, 'Timken' Bearings, Upgraded 'Wolf' Bolts, special 'Mil Spec' Washers, and of course our new 'Superflange'. All built into a Chemically Cleaned & Checked casing with here a 3.54 Ratio CW&P Comes with New Soleniod, Air Pipe and all Fittings, fully assembled ready to fit.

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

New ( From New Old Parts ) - A KAM 10 Spline Ratio 4 Pin Differential with New Genuine Land Rover 4.7:1 CWP

This is a pretty interesting Series Differential - We hve built this up from all new parts !.

The casing is a Aqua Blast cleaned Primed and Repainted Series Casing 'Split Nose' Type Casing (see Pic No 1) and has the required filler plug correct to this casing, complete with the bolt on Aluninium Nose cone, a Brand Spanking new Genuine LR 4.7:1 CWP, then we have fitted a Brand New / Old Stock Built KAM 4 pin 10 spline center with its hugely strong forged internal cross shaft.

There are few, if any 10 spline options to upgrade to nowdays, much of what is out there is in poor condition, so this offers a nice mix of new parts upgraded parts and yet from the outside when fitted it will look original !.

The inside is all upgraded, HD 10.9 Grade Crown Wheel Bolts + Nordlock Washers, upgraded Carrier cap bolts with 12.9 Grade Bolts and Nordlocks, all Timken Bearings and the inside is now seriously strong, but, on the nose cone we have fitted Original Series Bolts (all repolished) along with a new drive flange (upgraded seal) and new locking tabs etc to keep it looking all original when fitted !

Fabulous Blue Print (or yellow on this one) which shows the quality of these Old but Brand new Gearsets we have, Genuine LR and they show it - in both the quality of the build and the finished item

It's lovely, rare, and a bit of a one off, we doubt we will ever have another ...sadly

'Second Hand' 'Refurbished' 'Preloved' 'Used' ... Whatever you want to call them ... Consider these !

Whilst it would be lovely to have custom built, Brand New Pegged Ashlockers, with Heavy Duty Crown Wheels and Pinions - etc, not everyone can afford or justify the costs.

And we know this !. So, whenever possible we like to offer a selection of Used Differentials. All of these go through our workshops, and are rebuilt to the highest standards we can achieve, and built up to our 'Ultra Build Specification', the same as all our new Differentials. These Differentials have all been completely stripped to their smallest conponmet parts, every part checked, replaced if required and finally re-assembled. It is fair to say some customers have commented that these look like new - and that's why we are happy to put our name on them.

Yes they are 'Used' 'Secondhand', whatever your want to call them, but these offer a significant cost saving and give people the opportunity to upgrade which otherwise could be outside their budget. Often you will see comments relating to whats been replaced inside the units, and sometimes pictures too. As we have stripped cuddled polished and given them some proper love before the next new owner .... we called them 'Pre Loved' lol ( Yes, we need to get out more )

The Differentials listed below are NOT in price order.

They are listed in blocks of 'Types', starting with 'Standard' Replacement units, then '4 Pin Heavy Duty Units', 'ATBs' and 'LSDs', 'Auto Locking Differentials' and ending with 'Command Lockers', so scroll through our vast stock, and any questions just ring ! This stock below is subject to rapid change - what you see today can be gone in a flash - and when it's gone ...it's gone !.

If you are wondering about us having less 'Pre Loved' stock than normal ......

As we are currently extremely busy we are unable to build up many of the 'Pre Loved' Differentials we have here in stock to replace the stock we have sold in last 3 months
Here is a Selection of Land Rover Centres we have ready to be built - if you fancy any of these we can build to your chosen specification !

We will at some point get around to Building all of these, ......but not for a while.....

If you rather fancy any of these then just ring and discuss and agree what you fancy.... and jump the queue !.

Tru Trac 10 Spline ATB
Tru Trac 24 Spline ATB
ARB RD03 10 Spline Locker - Choice of 2
Kam 4 Pin 24 Spline- Choice of 2
ARB RD56 24 Spline Locker - Choice of 3

KAM 4 Pin LSD 24 Spline

Any of the above can be built up quite quickly to whatever specification you decide and we can agree to build for you.
We WILL get around to them all one day - but unless 'Pre Sold' it won't be for a while yet !

Some of these may well disappear - if customers phone and order - so be aware this is' 'unbuilt stock' - but - if its gone....it'a gone !"

Pre-Loved Series 1 80' Super Long Nose 4.88:1 CWP 10 Spline Circa 1948 / Early 1949

About as rare as you can possibly get in the world of Land Rover Differentials, and if you know what this is - you will know it is !

As the header says it's super rare 1948 / early 1949 Series 1 80' Super Long Nose 4.88:1 CWP. Fully rebuilt with all new bearings but with an unbelivable amount of effort with UltraSonic Cleaning and Polishing, it also means it's pretty much all original other than the new Bearings and Seal !. ALL the bolts including even the split pins are ALL original. It's also correctly repainted inside and out, and even the Locking Tabs have been repolished and reused. It's in exceptional condition, and who knows if we will ever have another ?.

The bearings for these are unique, seriously rare and even harder to find the best quality ones vs pattern rubbish being palmed off on the unsuspecting- and as such, when you do find them - bloody expensive. Even if found in dire states these diffs are extremely valuable carrying a large premium. So not only are they expensive to buy they are even more expensive to rebuild properly, compared to any other Land Rover differential. I am not even going to consider the labour hours spent on it, so whilst the price may seem high (if so just move on lol ) it was definately not a profit maker!

More like a labour of love - and I do love it !. (it's badly affected my 'Sad' side :O) )

YES - we would consider a similar unit in P/Ex against this, but you will need to speak to us as the CWP alone on these (if needing to be replaced) are £900 + VAT !, so, these are not cheap to either buy in or rebuild !

It's now currently sitting on my office desk, where I admire it daily - sometimes even several times a day :O)

It's so special it has had its own rebuild video done over the months we have been restoring it - Click to watch !

The price above is OUTRIGHT NO Exchange unit and No Surcharges etc required - but as mentioned we would consider a P/Ex Unit - Talk to us
( ...And as we say - but more so on this one - 'When this 'Has Gone' - it's most definately gone'..... and who knows if we will ever have or even see another we can buy...... )

Pre-Loved 24 Spline PUMA Long Nose Differential + 3.54 Crown Wheel Pinion - 11000 Miles !

This is the 2nd set of Late PUMA 110 differentials we have taken in P/Ex and are now ready for a new owner !.

Taken in P/Ex for some upgraded differentials front and rear what you are looking at is slightly higher milaegae - this one being 11000 Mile PUMA 2 pin differential, in 'As New' condition, if not even better.

As with the other 3 (we had 2 x 110s in for 4 x differential upgrades) even in the condition it came in to us we have still completely stripped it, checked, cleaned and rebuilt, with upgrades bolts new Drive flange and seal, full UltraBuild Spec plus our superflange upgrade.

Whilst it is fair to say that 2 pins differentials are weak, which they are, PUMA units are stronger than most due to having a central 18mm Cross pin vs the normal 16mm Unit.

so, if you are looking for a really REALLY superb 2 pin then this will be it.

Check out the superb blue check, 2 pin differentials don't normally come this good !

NO Exchange unit and No Surcharges etc required

Pre-Loved 10 Spline ARB RD03 Long Nose Differential with 3.54 Crown Wheel Pinion

This is now quite a rare unit, plus its in really really good original condition for one of these. Sadly many have been either abused or neglected, and often are only fit for the bin.

Howebver, this as you will see from the pictures, has come up really well. With a New Internal Cage, Piston and O rings and a good clean and re-polish it was all it needed. Its been rebuilt into a Imperial casing, and the Ratio is 3.54, which also means this has the filler plug (if needed ) in the diff housing - which is actually rather nice to have !

Avaialble 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

Pre-Loved 10 Spline ARB RD03 Long Nose Differential with Xcess 4x4 HD Flanges on BOTH sides ! + a 'Dana' 3.54 Crown Wheel Pinion

This RD03 had the typical issues of age and wear. The Non Air end flange was Cracked, and the Air end Flange was badly worn - and leaked as only a worn ARB can.

This would normally mean the unit would be scrap, but, we re-manufactuer these and in EN34T which are very very HD !. Problem is that each of the end flanges are over £100 each, and the air end coupler another £70+ odd , so it would for most people nake this impracticable to repair, but we decided to do it as the remainder of it was really ok, and needed to be given another lease of life. >/p> So, with 2 x Brand new End Flanges and a brand new air ring too, a new New Internal Cage, Piston and O rings its been properly rebuilt and is really now a HD Version of a 10 spline RD03 locker with our ends on it.

In all serioussnes if we priced this with all the new parts nobody would buy it, so although it's more than other RD03s there is a reason !.
We have priced it to sell vs what it should be priced at, so its really a bit of a HD RD03 special and a bit of a bargin !. When its gone its gone......

This also has a used but superb condition 'Dana' 3.54 CWP set out of a late low mileage Puma 90, 'Dana' make probably one of the best gearsetsavaialble in the world, and highly regarded, all in all this is a cracking RD03 locker.
Avaialble 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

Pre-Loved 10 Spline ARB RD127 (Current Model ARB) Long Nose Differential with a 3.54 Crown Wheel Pinion + Xcess 4x4 'Clamp Kit'

The ARB RD127 is the current Model ARB offer and is a 10 Spline unit. These are regarded as a stronger unit than the previous RD03 / RD56 Models, but suffer from a design change (which is a bit daft !) where the copper pipe for the Air System passes over the top of the Crown wheel.

It's the BIG achilles heel of these units, and the pipe can be chopped or rubbed by the Crown wheel when moving and the pipe can be 'Dragged' towards the wheel when the oil it thick and cold. The 1st you know about it is a massive air leak from a broken pipe !. Oh, and they are around £70 + vat to replace !.

We have rebuilt this ARB with new Thrust and drive washers, new Piston, O Rings and we have further upgraded it by the itment of our RD127/128 'Clamp Kit' which sorts out this pipe damage issue. In fact from all the Builds we have done with this upgrade + all the units we have sold we have not had ONE issue of pipe failure.

These RD127s cost a fortune new, probably because if you want a new 10 spline locker this is your only options - your sort of over a barrel, but this is as you can see a lovely unit, Full Ultra Build spec, superflanged and with a 3.54 CWP all ready to go to its new owner..

> Avaialble 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

Pre-Loved Tru-Trac 10 spline ATB Differential + 3.54 Ratio CWP

Tru-Tracs are a high quality ATB (basically a Limited Slip Differential which works via 'Gears' Vs 'Plates ) and being high quality AND as with other 10 spline units - really expensive new!.

The big advantage(s) of 'Gears' over 'Plates' is they don't require adjusting like a Plated LSD does, also, Tru Tracs don't need the specialist LSD Oils which are very expensive.
Just keep it topped up and changed with EP90 GL4 or GL5 and thats it - it is pretty much, a fit and forget (EXCEPT oil lol !).

We don't get these in very otfen as the owners tend to hold on to them !.

It really is a good condition example. We have stripped it completely, repolished the housing and internal gearset, full Ultra Build Spec, Super flanged and a Round Puma Flange to finish it of.

NO Exchange unit and No Surcharges etc required

Pre-Loved Detriot' Auto Locker' 24 spline Differential + 3.54 Ratio CWP

These are the 'Marmite' Differentials in the LR world - You either Love or Loathe. 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 love them, then this one is for you. Superb condition, from a fastidious one owner who upgraded it for 2 x lockers - It really is a good condition example

Its been stripped anyway, cleaned rebuilt and fitted with a quiet 3.54 CWP ready to fit. Full Ultra Spec Build and superflange upgrade and a nice round Puma Flange to finish it of.

If you loathe Detriots as some do, then we are sure there are other diffs here to tempt you other than this baby lol !!

NO Exchange unit and No Surcharges etc required

'Pre-Loved 24 Spline 110 4 Pin Short Nose Differential with 3.54 Crown Wheel Pinion

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 in the Front Axles), P38 Range Rovers Front and Rear and Wolf Military Land Rovers.

We are being asked more and more to offer these as rebuilt units. So we now rebuild these, 'Pegged' and 'UnPegged', this however is 'Unpegged'.

It's been totally stripped checked cleaned and rebuilt including a new Genuine Drive flange and Genuine Pinion Seal, plus our 'Superflange' upgrade, and full Ultra Build spec with upgraded bolts etc.

A 'NO Exchange' Purchase is possible, see 1st Option, but if you have a core unit to exchange we will ship on reciept of an acceptable unit, OR you can pay us an additional £100 so we ship and then refund on recipt of agreed unit back with us. Exchange unit doesn't mean 100% working and perfect - ring to discuss. We are very reasonable to deal with and sure we can help :D ). We will also consider taking a P38 2 pin unit in P/Ex (for not as much though LOL )

Pre Loved' Rebuilt 24 Spline KAM 4 Pin + Forged One Piece Cross Shaft + Ultra Build + Pegged Casing 3.54 CWP

A KAM Differentials '4 Pin'. These are seriously strong - take a look at the amount of 12.9 Grade bolts holding the 3 piece center together for starters !.

Internally this also has a 1 Piece Forged Cross Shaft - we have never EVER seen one break. It's a full Ultra Build Spec, then our Superflange upgrade, a Puma Late 'Round Flange' (Why for something spinning at speed off road would you use a cheap square one - ah, yes of course to save a few £s as its cheaper ?...We use these late Puma versions that are round whenever we can.

Add one of our Pegged Casings and a 3.54 ratio CWP ....and you end up with this .....a very nice seriously seriously strong 4 Pin Pegged Differential.

NO Exchange unit and No Surcharges etc required.

Just as with our Long Nose 'Super Pinion Flange' this a completely unique solution to the age old problem of Land Rovers various (dreadful) Pinion Seals and Shields, this unit being no better, so we are proud to now have an upgrade for these too. Unfortunately, and you may well know, the new drive falnges for these are anything but cheap, but hey ho eh ?

As with the Long Nose Upgrades - PLEASE DO NOT BUY If you're unable to potentially 'fettle' them to fit. Due to minor variations in LR Casings they may NOT always be a 100% straightforward fit, although we have had numerous feedbacks as to them being an easy fit ,...yours maybe the exception so please do think 1st!

Click for Video of these units being fitted, also look at the Long Nose Video above too.

Life is much simplier though - Just the 1 Kit comprising of a Xcess4x4 SPF Flange, New LR Genuine Pinion Seal, and a new 'Pinion Bolt' oh... and new Flange unit of course with the 'Super Pinion Flange' pressed on for you.

SPF (Super Pinion Flange) Replacement Heavy Duty Pinion Flange GENUINE LAND ROVER for all Short Nose / Wolf / P38 / TD5 Rear Differentials

This is the same as the above unit - except this involves a GEENUINE Short Nose Drive flange, and yes the quality is far far higher.
If you can justify the additional £30 its worth it !.These units (without our superflange upgrade) - ie JUST the flange itself are £147.74 plus vat !. so its £30 more than the one above with a superflange added, genuine seal and new bolt at £105.

Xcess Billet Machined Replacement for ARB RD03 + RD56 Air Flange Plate - Part Numbers 030120 or 030131 - INCLUDES New Timken Bearing

Our new RD03 and RD56 'Air Flange End Plates' replace the standard weak forged units, both of which are now 'no longer available'.

These are a direct replacement for either offering vastly increased strength, along with fixing the common issue of "the odd air leak ....or 6" ..?. These are CNC Machined from a solid billet of High Grade EN Heat Treated Steel, and, being significantly stronger these are far far more resistant to 'O Ring Grooving' on the Air Journal.

There are options which you need to study to ensure you order the correct kit.

For RD56 24 Spline units - Part Number 030131, you need 'Kit 1'. This is a new Xcess4x4 Air Flange complete with a New Timken Bearing 6 x 12.9 Upgraded Bolts and 2 x New ARB Air Seals.
For the Earlier RD03 - Part Number 030120, you need to order 'Kit 2', which is all of Kit 1, plus it has some additional parts - namely a new 'Uprated Air Ring' and locating Clip.

See the Video where we rebuild a RD56 with one of these new units : Click Here to see the Video of the Xcess4x4 Replacement Air Flange Unit

Xcess Billet Machined Replacement for ARB RD03 + RD56 Flange Plate - Part Numbers 020404 / 020406 - INCLUDES New Timken Bearing

For ARB RD03 and RD56 Diffs - The Xcess ARB Flange Plate. The Standard ARB 'End Flange' is a cast unit which is - well, how shall we put it ?...."Not very good" ? The CW&P bolt holes go oval or break through / crack away, the bearing journal tends to wear bearings become loose and or the casting can just plain crack into bits !

On RD03s - Part Number 020404 is wonderfully "No Longer Avaliable", and the same now for RD56 - 020406. And these are the parts that break, and as such your differential would now be sort of 'Scrap'. The 'Xcess ARB Flange Plate' will fit BOTH RD03s and RD56s ! CNC Machined out of a solid 8" billet of High Grade nickel chromium molybdenum steel (if your going to make something better - go the whole F hog lol ) oh...and heat treated. this Xcess Unit is not only thicker all over, but beefed up everywhere - like where the bolts clamp the CW - the thickness goes from circa just 1mm of casting to 3.2mm, and everything radiused for improvement of shearing issues. A seriously strong upgrade for ARBs. See the Video where we rebuild a RD03 with one of these new units : Click Here to see the Video of the Xcess4x4 Replacement Unit These come with a New Quality 'Timken' Bearing ready fitted. Please note : on the eralier RD03 units the inner journal is smaller and upgrading to this unit will possibly require a new bigger Air Ring Unit & clip. ARB Part Numbers are : RD-082002 (Air Ring) and RD-150602 (Clip)

Xcess 4x4 Spacer Ring for 4.7 Crown Wheel and Pinions being fitted to Metric 3.54 Centres AND Ashcroft P38 ATB Fitment

Our units are made from S275 Hot Rolled Steel, then 'Ground' giving a superior super flat finish & fit, vs many of the cheap adapter plates on the market, which have a very poor surface finish, often giving run out issues. These 4.7 'Spacer Rings' are required when you fit a 4.7:1 CW&P where you then need to convert the fit to match a 3.54:1 Ratio diff centre. These change the 4.7 positioning and offset - reseting the position so it all then lines up & fits together.

We also use these on our Ashcroft ATB units being fitted into a 'Short Nose' / 'P38' Casings. However, the OD is smaller than the Ashcroft ATB OD, this is because most Ashcroft ATBs we fit we use our Pegged P38 / Short Nose Casings - which require lathe work to reduce the ATB OD to this OD to give clearance. !

'Solid 1 Piece 'Forged Cross Shaft' upgrade for P38 / TD5 110 Rear 'Short Nnose' 18mm Differentials

This 'Forged Cross Shaft' upgrade adds massive strength to the TD5 110 Rear 4 Pin Short Nose diff, or The P38 Unit or even a replacment in KAM Differentials.

The Standard 4 pin has 2 'Pins', both of which have a 50% scalping 'Cut Out' where they cross, weakening them considerably !! and we see them snap regularly - pretty much destroying the entire Diff !. The 'Forged Cross Shaft' is unbelivably strong - used on majority of KAM units #we have never ever seen one fail - ever. ! As you can see from the pictures - these give a huge strength increase to one of the Short Nose units achilles heels !. The Unit can be purchased either outright on a DIY basis, or as an upgrade when we build or rebuild your differential.

BRAND NEW Old Stock GENUINE Land Rover Series 4.7:1 CWP set

The Series LRs CWPs being 4.7:1 Ratio means if you need a new one the options are limited.

As Differential builders we know that there are no decent 'pattern' 4.7 CWPs out there, we have tried them all, ...and they are ALL appalling quality mainly made in India, then rebranded and sold for differing prices by various retailers across the UK !. But they are all nasty !

However, we have now a number of GENUINE LR Factory 'New Old Stock' Units.

These are all as in the pictures, some are 'Military issue' from LR to the Military, and some are in Rover / Leyland / Unipart ! Boxes etc. All are Genuine brand new LR Units - boxes may vary LOL !.

As such these build really well, vs the pattern stuff (yes.....we have tried ALL the avaiable pattern gears - just don't is our advice ! ).

So, as to be crystal clear - We have put a few pictures up of the various types, as said all are Genuine LR issue, but the boxes etc vary between them, if you just order one / two we will send whatever is next on the shelf.....

But if you REALLY want one particular box for whatever reason ...then ring and advise which one you fancy ...either before of after you have bought and you can have whichever you wish for if that helps !

If you want a really good quality 4.7:1 CWP for your Series you will not regret investing in these !

BRAND NEW GENUINE LR Short Nose 3.54 CWP set

In the Land of Crown Wheels and Pinions there are Genuine and Pattern to choose from. In the land of 'pattern' ones there are nasty and not cheap, up to good and absolutely not cheap and even in the world of 'genuine' there are the very good, and the best - depending on who the maker is !.

THIS is the best you will find, and as you can see in the pictures this one is near polished finish. If you want the best 3.54 Short Nose CWP this is the baby. Just the one ....buy it or ask us to use it on your chosen build.

Pre Loved Low Mileage Ashcroft Short Nose CWP set

This is a Used and very low milage Ashcroft Short Nose 3.54 CWP set.

We know its low mileage as we built it, then the customer decided he wanted bigger tyres, and hence the 2 x diff came back and we rebuilt them with 4.1 Ratios, taking this back in P/Ex.

Its in pretty much as new condition, probably less than 800 miles !. Save yourself a lot of £s over buying a new one !

Pre Loved worn and a bit Rusty HD 4.1 Front Cut Ashcroft CWP

As you will see from the pictures (worse part pic taken of !) ...this unit has not been looked after and would be noisey if built up.

However, for a off roader / trailer where noise is not an issue this give a nice HD upgrade for a fraction of the costs of getting new omes which would be OTT !.

Matching Crown Wheel and Pinion, bag a little bargain if it suits - or buy it and we can build your diff for you with it ?

Brand New GENUINE BOXED LAND ROVER MANUFACTUER - LR 101 CW+P Set

These are as it says in the heading - Absolutely Brand New and Absolutely GENUINE (there are some dire pattern ones out there masquerading as Genuines !") BOXED Land Rover 101 CW&P sets RTC1393. The pic show that these come with the new collar and a set of the CW&P bolts. That's not rust by the way lol - thats proper old school packing grease so they will be perfect when its washed off !. Retail for these is stagering ....but we bought in at a good price so yes the price you are looking at to buy these is correct !!

KAM CV Kit Conversion Bushes KAM350 KAM351 KAM352

These are the bushes required to fit KAM CVs to the various |Land Rover Axle Types. We hold good stock of each, see chart for application required then call us.

KAM CV Fuseable Stub Shafts - Part Number KAM 340 / KAM340 185mm Aerospace Version

We have a few of these hard to source Stub Shafts.

These are the longer 185mm version for the earlier axles, We DO NOT have KAM 341s which are 160mm. You can if you are desperate change the stub axles etc for earlier units and then use these, both KAM340 and KAM341 use the same CV.

These are the last of the batch made at KAM, and are of the same grade as the KAM Aerospace Half shafts, which were made from Heat Treated '4340' alloy steel. When they are gone they are gone ! Call us to discuss.

ARB RD128 Copper Air Pipe Upgrade Protection Kit

The ARB RD128 Locking Differential for Land Rovers has a very very daft and very very soft 3mm Copper Air Pipe, which goes from the Air Ring on the Differentials Carrier to the outside of the differential casing - er...OVER....yes OVER the top of the Crownwheel....yup...Daft ! (with a BIG Capital 'D' ) ..... These are extremely prone to damage and chaffing, many being worn through or even ripped to bits by the crownwheel - turning the Locker into an expensive and time consuming repair job !. Even when repaired - with the replacement of the entire air ARB Coupling Pipe ( Not Cheap !), + Oil, time to refit etc, still leaves it just as prone to future damage.

This kit comprises of 2 x CNC Nitrogen Cut and CNC Folded Stainless Steel Brackets complete with Specially made P Clips, Allen Bolts, washers and Nylocs, plus a special longer Locking Pin for the Rir Ring and a set of longer Carrier Bolts.

What's REALLY good is that this Kit (Complete with simple to follow Instructions) CAN BE RETROFITTED safely without distrubing the differentials crucial 'Back Lash'. This kit not only locks the ARB Air Ring solidly in place but does the same for the Copper Pipe, making this 'Achilles Heel' of the ARB RD128 a thing of the past. Fit once forget and save yourself a axle strip down and repair costs...See the Video that both explains the problem and shows a Kit being fitted : Click Here to see the Video of the Xcess RD128 Pipe Upgrade Kit

ALL ARBs suffer from Air Leaks after prolonged use. Here you are buying a PAIR of O rings (as there are 2 x on the air collar seems sensible to sell a pair !) and these fit early RD03 and RD56 Models. These are a DIY Fit. These O Rings are on the Lockers Centre End Flange and NOT inside the Air Ring itselfThese come with simple pic and word instructions on how exactly to change them, without disturbing the crucial settings of your differential.

A PAIR of ARB' Replacement 'O Rings' for RD03 and early RD56 and Current RD127 10 Spline models - P/N : ARB RD-160206SP

ALL ARBs suffer from Air Leaks after prolonged use. Here you are buying a PAIR of O rings (as there are 2 x on the air collar seems sensible to sell a pair !) and these fit late RD03 and early RD56 Models. These are a DIY Fit. These fit INSIDE the Air Ring Collar

ALL ARBs suffer from Air Leaks after prolonged use ALL Models. Often this can be fixed with a Pair of new Air seals.

Thes eare the ones where the Air Ring is held in with a Spring clip. Even so for other models like the RD127 current 10 Spline these fit only Very Late RD56 and RD128 NOT RD127s !

ARB 5mm Air Fitting Upgrade Kit - Steel 'Swively' 5mm Push in Fitting Upgrade

The Standard 'Air Coupling Assembly' fitted to ARBs is a 'Bodgetastic El Supremo' mess Mr Heath Robinson would be proud of. This replaces the LOT. You end up with a nice simple push in (and easily removed if need be) steel swively 5mm push in fitting via a simple to DIY Fit, which once fully fitted can then angled to suit the blue air pipe work direction, and the ARB 5mm Airline just simply pushes in. Er...'Yippee' ..... This simple DIY fit 3 piece kit will upgrade either RD56 or RD128 (or other ARBs with the 3.3mm Copper thin pipe),and even RD03 early units (with a bigger air pipe - just drill out the brass union to same OD as ARB steel pipe and this then also fits that. Soooo much better !...God so much better lol

Ashlocker 6mm Air Fitting - Steel 'Swively' Upgrade Union

The Standard Air Union fitted to the Ashlocker is a Plastic Union, which can easy fracture and fail in off road situations, allowing Mud + Water to enter freely and wreck havoc inside your diff !. We have been asked by customers, and have sourced a supply of 6mm swivelly steel unions, which are a straightforward fit and upgrade. These also swivel, so they can be fully tightened and then angled to suit, and fit the standard Ashlocker 6mm air hose. These are fitted as standard to all of our Builds and Rebuilds, ......daft not to ! - However, many peeps are also fed up with the ARB 5mm pipework issues and fittings, so this kit will upgrade a RD56 and RD128 from the 'Bodgetastic ARB to a more common 6mm Unit, even RD03 early units (with a bigger air pipe - just drill out the brass union to same OD as ARB steel pipe.

ARB 'Blue Air Line' - Hose Joiner / Repair unit

Similarly, ARB Lockers use a odd sized 'Blue' airline. These 'repair' units are a high quality Air Tight 'Joiner' meaning you can carry as spares to repair a line should it get broken or pulled off in competition, or additionally - as we do - use as a 'quick disconnect' unit on the axle so diffs removal is simple - just push the end and the hose disconnects, leaving the expensive ARB seal assembly untouched on the ARB housing itself. These are STEEL construction, not the cheap plastic units you might see - and have a ridged outer surface which zippy ties hold in place very well. An essential for any off roaders tool kit and can literally save your day if you have a ir line issues

'Ashlocker' Air Line - Hose Joiner / Repair Unit

Ashcroft Locker Air Line Repairer. These 'repair' units are a high quality Air Tight 'Push-In Joiner' meaning you can carry as spares to repair a line should it get broken or pulled off in competition. Just push either of the ends and the hose connects / disconnects. These are STEEL construction, not the cheap plastic units you might see - and have a ridged outer surface which zippy ties hold in place very well. An essential for any off roaders tool kit and can literally save your day if you have a air line issues. Carry a couple and some extra hose, and you can get out of trouble toot sweet.

KAM Differential Weld On Axle Tube Mounting Ring

The KAM Differential Lockers (both early types with long locking shafts and up to and including the last of the range the 'Quill' Locker all use a Specially made Ring which is welded to the tube. These have been NLA (no Longer Availabl;e) for some time now, and its an essential part that if you bend a Axcle tube or need one, they are impossible to buy. So, as we like these lockers so much - we have had these remade, but this time from a Higher grade of Metal - S275 Hot Rolled Sheet, and, this time in 8mm plate, and with machine tapped holes,linished and deburred for a superb fit.

Instructions will be sent as to the best way to weld these into place.One of the issues around these mounting rings was the metal was too thin (hence 8mm now) and the 6mm Allen bolts too weak allowing the bolts to shear off if the cover was really 'clouted' causing a real problem to sort - we have upgraded to 100mm thresaded bolts for extra strength - You will need to drill out your existing Aluminium cover to allow the larger bolt. Comes with 18x new Bolts too !
