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). 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. We have had just two of these fail out of 509 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 !. Available either Exchange or Outright with No Exchange.

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

Our 'Standard' Pegged Differential Casings offer massive increases in strength - (watch the video in the video section if you haven't already), 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. 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 '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 you teeth with whatever you have managaed 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

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 3.54 Ratio CW&P and Fully Refurbished Casing. 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.

Brand New 'Fully Built 'Ultimate Spec' Ashlocker - 4.75 Reverse Cut HD CWP + Pegged Casing + Hi Flow Washers + Tablock Upgrade

This is EVERYTHING we can do to make the strongest Ashlocker you can buy.

Starting with a Brand new Ashlocker, upgraded internally with our Hi Flow Washers, and then our Tablock Upgrade to finish it off.
A Front Cut HD standard 4.75 Ratio HD CWP, a full ultrabuild into one of our new Pegged Casings, add the superior Puma Type round drive flange, and our superflange. Oh, and a Front Cut Oil Vane too.
This is the currently the very highest specification we can build, and, being a Front Cut HD 4.75 Gearset, this is for a front axle ONLY

Truly a Fab differential, avaialble with or without the additional hose switchgear fitting soleniod etc, which if required is just an extra £30

NO Exchange unit and No Surcharges etc required

'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
ARB RD128 24 Spline Locker

ARB Short Nose / 110 / P38 / TD5 110 Rear - ARB RD138 24 spline Locker
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 24 Spline Quaife ATB in Pegged Casing number 700 + HD 3.5 Rear Cut Ashcroft 3.5 CWP

Oooo Sir !

Now again again we have something really special - this is one of those moments.

Its a 24 Spline QDF12K 24 Spline Long Nose Quaife ATB, complete with our full ultra build spec, including a rear 'Oil Vane' upgrade. Built into our Pegged Casing 'Number 700' along with a HD Ashcroft 3.5 HD Rear Cut CWP, and Superflanged too

This is the Rolls Royce of ATBs and although the center is preloved its been stripped cleaned and rebuilt, and offers a significant saving over if this was a new one !.

Just the one - and when its gone its gone. Oh, and being its in casing No 700, its comes with its own video (coming here soon !)

NO Exchange unit and No Surcharges etc required

Pre-Loved 10 Spline Tru Trac Rear ATB with 3.54 Crown Wheel Pinion

Lovely 10 spline Tru Trac Rear ATB

NO Exchange unit and No Surcharges etc required

Late Series Split Casing Differential with 4.7:1 Ratio CWP - Fully refurbished and very Original

This would be a superb differential for any owner who wants originality on their new replacement Series Differential.

With this unit it was completely stripped down, and although the Crown wheel and Pinion were in amazing condition (see picture of the finished buils 'Blue Check pattern !), unfortunately, the 4 x gears in the center of the unit were all damaged. However, we carry brand new (very very old) Genuine LR Gears in stock, so, as you can see in the picture this unit now benifits from a brand spanking new set of center gears !. It also retains all of its original bolts which have been ultrasonically cleaned and repolished and the originality is maintained right down to the correct colour paints being used inside and out, as was 'Facrory' on these units, and the lock wired Carrier Bolts.

All new Timken Bearings, a new genuine Pinion seal, new Dust Sheild anmd drive flange have been used, but everywhere else where we possibly could - its all very original.

NO Exchange unit and No Surcharges etc required

Pre-Loved Very very early Series 1 80' 4.7:1 Split nose 1949/50 10 spline Ratio Differential - Fully rebuilt 100% original !

WOW !

You are looking at a very early Series 1 80 inch differential, circa 1949 ./ 1950. It can be dated to this from clues such as the single lock tabs on the CWP bolts (the later 51 etc had lock tabs covering 2 bolts at a time, the fact the really early casings we not painted inside, and nor was the center. (yes it's very much rustling anoroak time LOL). But boy what a unit. We bought this in from a customer who found it under his bench moving house, and reckons it was under there for at least 35 yeasrs as his spare....and looks it too!

we have stripped in completely, Ultra sonic clean every part, then repolished the gear sets, and used all the original bolts (check out the brand name on them !) even down to repolishing the original split pins and then to finish it off lock wired it as it should be.!

We have pretty much reused every original part, the only new parts are the Bearings - all replaced with Timken, new Genuine Seal, new Brass gasket, new Genuine new old stock thrust washers, and pretty much everything else has been refurbished to as good a stanbdard as we can get and we have ended up with a fabulous unit seen here

The quality screams out at you - 'Cross Drilled' gearsets, bronze plated cross shafts etc etc. Old School quality, and in exceptional condition, great blue check and quiet too !

*** PLEASE NOTE : THIS IS NOT THE EVEN EARLIER SUPER LONG NOSE SERIES DIFFERENTIAL ***

Stunning Pre-Loved Late Military Spec - 4 Pin Centre 24 Spline + Brand New Genuine LR MOD CWP 3.54 + Pegged Casing

....And if you think the unit above is rather nice - try this !...........Currently in Build - so final pics to follow !

As we said above, we refubish and rebuild many 4 Pin Differentials - but - every now and again we get something really special - and this is another of those times!.

Here we have an amazing condition Genuine very late and highly likely 'Ex Military' spec Land Rover 4 Pin Center - the condition is so good it could be new, but we can't be sure - but just look at the pictures. We think this is MOD because it came as a bought in job lot of ex Military Differential parts, and one of the really nice things in the new stock was a BRAND NEW Genuine LR 3.54 CWP to make this unit complete when built and has the MOD markings on the CWP Box !!

So, what we have done is further strengthened this 4 Pin Center by fitting one of our brand new one piece Forged Cross Shafts, and then rebuilt the Center with the new MOD 3.54 CWP set into one of our new Pegged Casings. We often say that a diff is a 'real beauty' or even 'high up in terms of quality', but in the land of 4 Pin differntials frankly we don't think you can get a stronger or better LR 4 Pin Differential than this one. Sadly, we only have enough for this one unit, so when its gone its gone, but this is quite some differential !.

NO Exchange unit and No Surcharges etc required

'Pre Loved' Rebuilt 4 Pin 'Wolf' 'P38' 'Short Nose' 110 130 Rear Differential

These are the other type of Land Rover Differentials. Know as 'P38 Diffs', or 'Wolf Diffs' or 'Short Nose Diffs'
To clarify, these are the units 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 beiung Unpegged.

These are super strong athis unit has been as all our diffs are - completely stripped down to conponent parts, innspected cleaned and reassemabled with new parts and upgraded 12.9 bolts on centre + Ultra Spec Build, and with the 'Short Nose' version of the 'Super Pinion Flange'.
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 £50 so we ship and refund on recipt of agreed unit. 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 ARB RD128 24 Spline 3.54 CWP + Without the daft 'Over the CWP' normal copper pipe issue !.

Another RD127, the current ARB model - 10 spline Locker

Its been completely stripped, added a set of our special Hi Flow Washers thrusts, plus new seals, and internal piston then with a full UltraBuild, and having the benifit of our 'Air Pipe Clamp Kit' - which sorts the common issue of having the copper air pipe run over the top of the crown wheel getting broken easily !.

As with the vast majority of our builds this also has our superflange upgrade too, and our stainless push fit ARB Upgrade for the air hose connection.

NO Exchange unit and No Surcharges etc required.

SPF (Super Pinion Flange) Replacement Heavy Duty Pinion Flange Kits for all Long Nose Differentials

The 'Super Pinion Flange' is a completely unique solution to the age old problem of Land Rovers various (dreadful) Pinion Seals and Shields.

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.
Click for Video explaining fitting process and potentially what might needed in 'tweaking' them to fit. er ie LR tolerances are 'not quite as good' as a 5 Axis CNC Machining Center. !

Kit 1 - 'Castle Nut' Kit
Pinions with a Castle Nut + Split Pin is this Kit. It will also fit the 4 Spline older Flanges and the later 24 Spline.
Kit comprises of a SPF Aliuminum Flange, New Corteco Pinion Seal, new 'Castle Nut' and Split Pin.

Kit 2 - 'Central Bolt' Kit.
Pinions with a 'Bolt' screwed into the end means you have Kit 2. Pinions may be Round or Square - fits either.
Kit comprises of a Xcess4x4 SPF Aliuminum Flange, New Corteco Pinion Seal, and a new 'Pinion Bolt'

Kit 3. - 'Nyloc' Kit.
On Differentials with a 'Nyloc' nut on the end of the Pinion, including Discovery 2 '3 Bolt Flanges' this Kit.
Kit comprises of a Xcess4x4 SPF Aliuminum Flange, New Corteco Pinion Seal + new 'Nyloc'.

Kit 4. - TWO of any of the above Kits - 'Mix n Match' !
If you would like to buy a Pair of SPFs then Kit 4 is the one to buy.
You can have 2 x of whichever Kit(s) you need - just advise on payment as to which ones you would like - and yes, you can have different ones,
as sometimes the front and rear Differentials may need different kits. With Kit 4 buying 2 also gives you a small discount.

Kit 5. - A Full Super Flange Kit (has all 3 Pinion end types) + NEW 'Round Type" Late Pinion Flange - Pressed on ready to fit !
Here you get as in the Picture - A New 'Late Type' Pinion Round Type Drive Flange, with one of our Superflanges already pressed on ready to fit, and the new seal, and ALL 3 x Pinion end fittings

Kit 6. - A Pair - i.e. 2 x Full Kit 5s as above.
That's 2 x New Round 'Late Type' Drive Flanges, both with new seals, all 3 x pinion end fittings, and 2 x of the SPF pressed on all ready to fit.

Kit 7. - A New SQUARE 4 Spline Drive flange (Early LR Differentials) + new SPF Fitted Inc Seal etc
On Earlier Land Rover Differentials, the pinion has a 'Coarse' 4 Spline vs the later 24 Spline version. This Kit is for 1 x Square coarse 4 spline Drive Flange with a SPF Fitted, and comes with new seal etc.

Kit 8. - A Pair of New SQUARE 4 Spline Drive flange (Early LR Differentials) + new SPF Fitted Inc Seal etc
That's 2 of 'Kit 7' - ie 2 x Square coarse Drive Flanges, both with new seals, and 2 x of the SPF pressed on all ready to fit.

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

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.

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. !

'Hi Flow Planet Gear Shim Pack (Set of 4)' for Ashcroft Ashlocker & P38 Short Nose Differentials with 18mm Cross Pins

Standard Ashcroft 4 Pins or Ashlockers or the Short Nose 4 Pin 18mm Center Pin Differentials all share the same 'cheap & a tad nasty' Thrust Washer on each of the 4 Planet Gears (Pic Left).
These are 'OK', they do the job - which is to aid 'slippage' between the Differential Center and the 4 Planet Gears by having a sacrifical shim with oil on each side.

However, in heavy competition or off road use these standard shims can easily be super heated due to oil starvation and can actually damage / weld / destroy what they are designed to protect !. This occurs when high RPM and high side loadings force the oil out - and it can't get back in. .

This simple and effective upgrade via 'Hi Flow Shim Packs', (Set of 4) for the above differentials. (Pic Right) gives vastly superior protecttion, the specification and design means faster and more constant oiling to the gears and this style of Hi Flow Shim is commonplace on very high end racing differentials, and for good reason !

The kit can be purchased as either a 'DIY pack of 4' or as an upgrade when we build or rebuild either Ashclockers, Ashcroft 4 Pins or P38 Short Nose units. Ring to discuss. Ok, Not cheap, but in the overall scheme of things not a fortune either when you consider the possible damage and costs they can save.

'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.

** Special ** BRAND NEW KAM Ultra Low Ratio CWP Set 2.83:1 for Long Nose Casings

We have secured just a few of these rare units, these are BRAND New and highly prized in Cummins type engine conversion where the low Max RPM of the engine means poor top / cruising speeds on standard 3.54:1 Gearing. These are Brand New KAM Units, matched CWP sets. We would strongly recomend these need to be pegged if your using High BHP and Torquey Low RPM engines behind them !. Oh, and a LOT Cheaper than buying from KAM !

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

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.

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 !
