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 !.

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 Ashcroft ATB 24 spline Center + Brand New Ashcroft 3.54 CWP + Full Ultra Build Spec

We were asked to build this by a customer - only when he turned up to collect it - and we had a chat did he suddenly understand he was badly advised on what to buy from us, so we 'Undid' the deal, and he left with a completely different Diff - an ashlocker - which he delighted to have !

So, we have now this all built up - which we rarely have - all brand spankingly new - and all ready for fitting !.

The specification is its a Brand New Ashcroft ATB (limited Slip but works through 'Gears' vs 'Plates' and doesnt need special oils either - EP90 is what these like) and its been built to our ultra Build Spec + a Brand new Ashcroft 3.54 CWPs and then fully built up into one of our refurbished Casings

Quiet as a mouse, great blue check. Some diffs even with all new bits turn out better than others - this is a beauty !

NO Exchange unit and No Surcharges etc required

Brand New Ashcroft ATB 24 spline Center + Brand New Ashcroft 3.54 CWP + Full Ultra Build Spec+ new Pegged Casing

These are getting more and more popular, so we now try to carry some all built up ready for immeadiate shipping !

The specification is :
a Brand New Ashcroft ATB (limited Slip but works through 'Gears' vs 'Plates' and doesnt need special oils either - EP90 is what these like), Full Ultra Build Spec including our hugely popular Superflange upgrade, a Brand new Ashcroft 3.54 CWP and then fully built up into one of our Pegged Casings

Quiet as a mouse, and being a new CWP a really good blue check.

NO Exchange unit and No Surcharges etc required

Fully Built up New Ashlocker + New Ashcroft CWP 3.54 Ratio + Built into an Imperial Casing + Hi Flow Washers

Brand new Ashlocker + Brand new Ashctoft 3.54 CWP into a Standard 'Imperial Casing' ( These 'Imperial Casings' fit all coil sprung long nose axles - its just there is no filler plug on the axle diff pan on early axles - 'Imperial Casings' have filler plugs in the casing themselves - it just means you'll have 2 ways to fill with oil if you have a later axle with a filler in the diff pan !.

In addition to the full Ultra Build Spec and Imperial Casing, we have also added our 'Hi Flow Washer' conversion for improved oil feeds to drive gears (see picture)

This differnetial can be bought as is - or - for a bit more you can add the New Switch, New Hose and new Fittings and New Soleniod etc

' New (Ex Display) ARB RD138 24 Spline Air Locker for 'Wolf' 'P38' 'Short Nose' (110 130 Rear)

We buy in all sorts of Differentials !. This is one - a 2 months old ! ARB RD128 Center for the 'Short Nose' Differentials on TD5 110 rears 'Wolf Diffs' or 'P38 Diffs'

This is pretty much brand new at just 2 months old !. Owner hit diff pan and squashed the copper air pipe, being a daily driver, and the part not avaiable for 4 weeks traded it in for an ashlocker ! Also very unusally, but desireable - is this center has been built up with a superb low mileage 'Dana' Crown Wheel + Pinion into one of our Pegged Casingsw. These Dana CWPs are just stunning quality vs the normal LR CWPs, they turn up now and again but they always make for a silent diff, and this is just that and with a classic blue check pattern.

It's had our full 'Ultra Build Spec Build', and it comes complete with the 'Short Nose' version of our 'Super Pinion Flange', plus a proper upgrade to the external 'air coupler' via one of our stainless swivelly push fittings to replace the ghastly ARB set up !.

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 £30 so we ship and refund on reciept of agreed unit. Option 3 means you get all the additional parts needed to fit this - all new - just add the Baby ARB Compressor kit and it will be complete !. Exchange unit doesn't need to be 100% working and perfect - ring to discuss. :D ).

'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 !.

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 ***

Pre-Loved Very Low Mileage 'Ashcroft' Standard 3.54 Ratio 10 Spline Differential + Xcess 4x4 'Superflange' Upgrade

Preloved as in 700 Miles if that !.

Taken in P/Ex this is a as new Ashcroft Rebuilt unit, although we have converted it by upgrading it with a new superflange unit and seal.

We looked at it, and decided daft to tear it apart for the casing, so here it is. New From Ashcrofts this is £438 Inc Vat and shipping (and we have added £72 worth of superflange system to it, this, 700 Miles later is something we would like gone, so as a special offer its £200 + Shipping

Stunning Pre-Loved Late Military Spec - 4 Pin Centre 24 Spline + Dana 3.54 CWP Gearset

We come across refubish and rebuild many 4 Pin Differentials - but - every now and again we get something really really special - and this is one of those times !.

This is a very late Military specification 4 Pin Differential, which is all the nicer for having a 'Dana' CWP set.
Land Rover do not make their own CWPs, they have a selection of gear manufactuers do this for them - one such maker is 'Dana', regarded as possiblly the very best of what they buy in, and probably cost LR more then any others - so you don't see many of them !. Coupled a Dana CWP gearset with pretty much an 'As New' Land rover 4 Pin Center, and you have a really super smooth quiet and sttrong diff, and possible right up the top in terms of quality and desirability, and we have converted it so it also now benifits from our upgraded Superflange.

Whilst this could be used in anything from an ARC trailer to a Racer it would really be sacriledge - and we would say this would be a perfect upgrade for a road based LR looking for a proper serious strength increase + a super quiet unit. NO Exchange unit and No Surcharges etc required

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 !.

Exceptionally badly Pre-Loved 'Hyena' Differential - 4 Pin Centre 24 Spline + Horrible 4.1 HD CWP + Repaired Pegged Casing

Xcess 4x4 Rescue Centre Presents - 'Adopt a sad nasty Diff'

Here we have a VERY cheap diff, made out of bits we didn't have the heart to bin - it's truly made from scrap, but as well as we possibly were able.
The price is pretty much the parts and labour and cleaning and repair costs plus a few used parts to make the center live one more time ..
But...for an off road truck this is a super cheap pegged 4.1 HD CWP 4 pin .....read on ...if you dare ...

Heavily damaged Ashcroft Pegged Casing - (Heavily Repaired)
Seriously damaged internals on 4 pin - (new used internals fitted after repairing)
Rusty nasty 4.1 Front Cut HD CW&P - (rust removed – still rather nasty)
Don’t even think about it for road use ! - It’s a very very cheap Pegged + 4.1 HD CW&P + 4 Pin Centre - to suit pure off road 4x4 / Trailer etc

Save on your horn - We guarantee peeps will hear you coming from far far away as its going to howl like a wolf looking for its lost mate

NO Exchange unit and No Surcharges etc required

Rather cheap - Pre-Loved 4 Pin Centre 24 Spline + Tad Noisey Ashcroft 3.5 HD CWP

Here we have another cheap Differential for what it is !

It's a 4 Pin center - so nice and strong + it has a Pre Loved 3.5 HD Ashcroft CWP, and all built up to our ultra build spec.
The HD CWP was bought in P/ex re a Ratio change, we thought it would be nice and quiet, but, with all diff building you really just can't tell until its fully built, and, on this unit it is not going to be as quiet as we would like.

No, its not suitable for a late quiet road based daily driver who wants super silence, but if you wnat a seriously cheap HD CWP 4 Pin have say some 'INSA Turbos' and a rattly Diesel, plus other rattles 'n noises - this is a fraction of the cost if you wanted to buy this set up all new !

We have thought long and hard and decided to basically cut our loses and sell super cheap vs waste another day rebuilding it with another CWP, and then what do we do with this CWP ?

so, someone will be getting a very cheap HD diff, albiet with some noise maybe .....

As with the Long Nose Upgrades - PLEASE DO NOT BUY If you're unable to potentially 'fettle' them to fit.

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.

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 !

Used 4.1 Ratio CWP - Maker unknown ! - £150 !

Well, this is odd !.

We have purchased in a pair of unknown make of 4.1 CWPs, one has gone - here is the last of the 2 !

Its not a HD CWP - Most likely to be a Rover Umit from something, but we are just not sure what. It looks likje a standard 3.54 or 4.7 gearset, but we have triple checked and it is defo a 4.1 !. However, as a 4.1 this gives a very cheap solution for anyone looking for a upgrade to 4.1s, rather than new Ashcrofts gears at £234 for a gear, this is Just £90.

Is new better ? - Yes absolutely, but not everyone can afford the best at £234 to get a 4.1 CWP ?.
You can buy this as a DIY build, or we can build this into your chosen new differentiasl. Condition is actually quite good !

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

A PAIR of ARB' Replacement 'O Rings' for early RD03 and early RD56 10 Spline models - P/N : ARB RD-160221 ( But No Longer Available from ARB)

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

A PAIR of "ARB' Replacement 'O Rings' for later RD56 and Current RD128 models - P/N : ARB RD-160235SP

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