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 New Ashcroft ATB + NEW Ashcroft 3.54 Ratio CWP into Megasquirt V8 Pegged Casing

Ooops !. This is a cancelled, or rather a 'changed too late order' !. Seems he took the wrong advice, and after letting slip his plans we said 'Er ...Noooooooooooo....you do NOT want a ATB because ....' This was followed by a'Oh ****' comment and a rethink ...

So, here we are with a Fully Built up ready to fit in Ashcroft ATB with a New Standard Ashcroft 3.54 CWP in one of our own Pegged casings, Full Ultra Build spec, inc our special superflange. We have had a 'Nice drink' from customer for messing us about and saving him a very very expensive mistake buying an ATB (which is nice) so this is cheaper than it normally would be, as its not a unit we would normally build for stock !.

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

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 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'.

Watch the videos of our Pegged Casings and see why they are such a good idea !. Our 'Ultra Build Specification' means your Differential is built 'Up'to a Specification' not 'Down to a Price'.

'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 )

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 KAM 4 Pin Centre 10 Spline !! All New Parts + Forged Cross Shaft + 3.54:1 Ratio

Yes, you read this right !. A Brand New KAM 4 Pin 10 spline Yes TEN spline Differential complete with a Forged Centre Cross Shaft.

This was pretty much an abandoned KAM project back in the 80s, when they decided to concentrate on 24 spline Differentials, leaving this project on the shelf !.
Recently we bought in a huge amount of stock, including these brand new unused project units. Here we have built up 2 x them. We have had to have some CNC internals made as these were never actually finished, so here we are in 2018 project finished ! This unit offers a significantly stonger differential, and at a very attractive price, and as you would expect built up to our normal 'Ultra Build Spec'

NO Exchange unit and No Surcharges etc required

Pre-Loved Very Standard Series 4.7:1 Ratio 10 Spline Differential in Early Casing ( + Filler Plug on Casing !)

We rarely do Standard LR Differential rebuilds. The reason being is the Labour and parts costs are pretty much the same - be it a 'top of the range' Ashlocker with HD CWP at £1200 + or as here a Standard Series Diff. This is a Cancelled Order.

But, its pretty much the same as all our Ultra Builds, all Timken Bearings new shims, new seal, new drive flange and a superflange fitted, Cleaned and refreshed casing, early type with the filler plug in, all Upgraded Bolts everywhere etc etc. As good a Series 4.7 Diff as you are going to find. Bit of a Bargain, and unlikely we will have another for some time !.

NO Exchange unit and No Surcharges etc required

Pre-Loved Very Standard 3.54 Ratio 10 Spline Differential

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 £295 + Shipping

Pre-Loved KAM 4 Pin 24 Spline Centre + Forged Cross Shaft + Pegged Casing 3.54:1 Ratio

This is a 'As new' KAM 4 Pin Differential we have built up from us buying vast stock, enabling us to offer a few of these highly regarded units. All 'Ultra Build' Spec, Pegged Casing, 3.54:1 CWP, New Thrusts on all the Gearsets, New upgraded bolts etc etc and of course including our superflange. A significant saving over new, and also these having the 'Forged Cross Shafts' make these one, if not 'the' stongest 4 pin Differentials ever made.

NO Exchange unit and No Surcharges etc required

Pre-Loved KAM 4 Pin 24 Spline Centre + LSD (limited Slip Differential)+ Forged Cross Shaft + Pegged Casing 3.54:1 Ratio

This is a 'As new' KAM 4 Pin Differential we have built up from us buying vast stock, enabling us to offer a few of these highly regarded units. All 'Ultra Build' Spec, Pegged Casing, 3.54:1 CWP, New Thrusts on all the Gearsets, New upgraded bolts etc etc and of course including our superflange. This unit has the optional LSD pack (limited Slip Differential) offering improved traction over the open 4 pin, but shares otherwise the same internals so is regarded by many as the strongest 4 pin units ever made, and with LSD too ! A significant saving over new, and also these having the 'Forged Cross Shafts' make these one, if not 'the' stongest 4 pin Differentials ever made.

NO Exchange unit and No Surcharges etc required

Pre-Loved Tru-Trac ATB 24 Spline 3.54:1 Ratio

Lovely Condition and very standard True-Trac these give you hands free improved traction over any open differential. Ultra Build Spec + ready to fit. Normally we do 2 pictures from different angles of the differential for sale- but - this one has such a stunning blue check we have shown that instead !

These use a gear type torque bias design (no clutches or friction plate to wear out) giving progressive torque bias. When both wheels have equal traction there is minimum torque bias, equal torque will be transmitted to each wheel. In this state the diff will be unnoticed by the driver even when used in the front axle. If one wheel begins to loose traction the gears work against each other the effect of this "inefficient" gearing is to multiply the torque on the wheel with the least grip i.e the one that is trying to spin by up to a factor of up to three to enable the wheel with grip to drive.

The advantages of this type of diff centre are that it is very soft in operation and virtually undetectable when driving on the road, disadvantages are, because of the way they work you need preload on the spinning wheel in order for the diff centre to bind up and transfer torque to the other wheel, in some situations such as a severe axle twister when there is no preload the Truetrac will do very little. It can be fooled into working by left foot application of the brakes to pre load the spinning wheel but really in this situation a locker is required. We would also strongly recomend you add HD shafts !.

NO Exchange unit and No Surcharges etc required

Pre-Loved Tru-Trac ATB 24 Spline + Pegged Casing 3.54:1 Ratio

Pre Loved Fully Built up ARB RD56 24 Spline + 3.54 CWP + Refurbished Ashcroft Pegged Casing

These are hugely Popular Lockers.

The Earlier ARB 3 piece RD56 24 Spline Locker pre-dates the current RD128, but many do prefer it !. This is a Traded in Example, which needed lots of new parts. As such it has had - New Thrusts all round x6, new HD Xcess4x4 Air End Flange, New Xcess 4x4 CWP End Flange, ( both addding massive strength increases to the ARB cast units which had failed ), New Genuine ARB Center Cage and New Piston and 'O' rings, then Rebuilt to Ultra Build Spec with a 3.54 CWP. Note : This unit cannot be Superflanged sadly so has a Late Round Puma Drive flange and dustsheild.

Available either on its own, or, complete with New Soleniod, new Air Pipe and all new Fittings.

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

Pre Loved Fully Built up 'Tab-Locked' Ashlocker + New Ashcroft 3.54 CWP into Megasquirt V8 Ltd Pegged Casing

So, its done no real work not supplied by us, and badly built up so its been completely stripped rebuilt with Hi Flow Washers and new Tab Lock End Plate and new Ashcroft 3.54 Crown Wheel and Pinion as the original one was shocking, then popped into one of our own Megasquirt Pegged Casings

So, it's our normal Full 'Ultra Build' Specification. with a mix of new Genuine LR Parts, 'Timken' Bearings, special 'Mil Spec' Washers, and of course our 'Superflange' conversion. Available either on its own, or, complete with New Soleniod, new Air Pipe and all new Fittings.

It has a Ashcroft Heavy Duty 3.5 Crown Wheel and Pinion, and also upgraded to our Tab Lock system. New this unit would be over £1580+, this, although looks like new is 'Pre Loved', so with thisTop End Specification there is a HUGE saving to be had. Full Ultra Build' Specification.

Pre-Loved 'Military 4 Pin' 24 Spline - Pegged Casing + 6 Hi-Flow Washers + Forged Cross Shaft + New Ashcroft 3.54:1 CWP

These are at best rare, and in this condition even rarer. This is a Military 4 Pin centre, stripped cleaned polished and rebuilt with its Forged Cross Shaft having our unique 'Hi-Flow' washer conversion for better oil lubrication. This unit is a significantly stonger differential, further benifitting from one of our new 'Pegged Casings'. Full 'Ultra Build Spec'including 'Superflange Conversion', and a new Ashcroft 3.54 CWP to finish it off.

NO Exchange unit and No Surcharges etc required

Pre-Loved Rare + Genuine Land Rover Factory 'LSD' Limited Slip Differential 10 spline 4.7:1 Ratio

This is about as rare as rare Land Rover differentials get !.

A GENUINE LR Factory 'LSD', these cost a small fortune as a Optional Extra, and were mainly the preserve of Military Upgrades, only a few made it into Civilian Vehicles.... due mainly to cost !. These are normally beyond repair, but this one was a sleeper, having spent the last 20 Years under a bench !. We have completely dissasembled the unit, cleaned everything, had the casing chemically cleaned then repainted in the corect Military Green.

This is quite literally in stunning condition, rebuilt with all new Timken Bearings and to be as original as when it left the factory. The 4.7:1 Crown Wheel and Pinion are equally original, and the unit is both smooth and quiet.

I doubt we will ever see another, and if we do, doubtfull to be in this sort of condition. A piece of Land Rover history !.

NO Exchange unit and No Surcharges etc required

Pre-Loved Detriot Auto-Locker 24 Spline + 3.54:1 Ratio

Again, a little bit like 'Tru-Tracs' the Detriot 'Autolockers' are loved or loathed, you decide, but they give you 'hands free' improved traction over any open differential. Very Strong and a complete unit - no need for any electrics, plumbing or compressors, just bolt in and it's job done !. Full Ultra Build Spec including superflange conversion ready to fit

These are often referred to as 'Automatic' Lockers. They work via maximising traction delivering 100% of the torque to both drive wheels. These are engineered to keep both wheels in a constant drive mode, and have the ability to automatically allow wheel speed differentiation when required.

NOTE : Only ever fit in the rear axles do NOT fit in Front axles. We would also strongly recomend you consider adding HD shafts !.

NO Exchange unit and No Surcharges etc required

Brand new (old Stock) KAM 24 Spline 4 PIN Limited Slip Differential Centre - Call us to discuss how you would loike it Built !

We recently purchased a massive amount of stock from a well respected Land Rover Differential Builder who has decided to retire.

We now have for sale a Brand New KAM 4 Pin Centre with the Added LSD (Limited Slip Differential Pack) ready to be built up into a casing, but, as we have only this one, we decided NOT to 'Guess' the build, but to offer it here as a new centre unit to be built up to the buyers spec, so, you can choose CWP Ratio, Pegged or Not Pegged etc etc.

These KAM 4 Pin LSD Units are £510 new, this ise £325, with whatever your build spec is on top. You get it built to the spec you want, and save a significant amount of money. We decided that if we took a wild guess and just built it, we are certian its going to be wrong lol.

So, if you fancy a KAM 4 PIN LSD unit built up to your spec ring for a chat.

Fully Refurbished REAR KAM 24 Spline 4 PIN Limited Slip Differential Centre - Call us to discuss how you would like it Built !

This unit is a Brand New KAM 4 Pin Centre with the Added LSD and has been taken in P/Ex stripped and cleaned and fully refurbished. We have this all ready for a build, rather than play 'Guess what we ought to build with it' ....and then get it wrong lol. Phone and disucsss how you would like this to be built, 'Pegged' 'Unpegged' 'CWP Ratio' etc etc. Huge saving over new. This has been and has been reset to be a rear unit (heavier LSD clamping (we can explain on a call to us), but can easily be converted to the 'Softer' Front LSD settings

So, if you fancy a KAM 4 PIN LSD unit built up to your spec ring for a chat.

Fully Refurbished REAR KAM 24 Spline 4 PIN Forged Cross Shafted Differential Centre.

So much of this is new !. From buying in the vast stock following Crown Diffs retiring we have looked and found we have enough for this unit ! New flanges each end, New Thrusts on all the Gearsets, New upgraded bolts and lovking dog bolts etc etc. Its all now built up and will shortly be built into one of our new Pegged Casings with a good used checked and cleaned 3.54:1 Ratio, and of course a Full 'Ultra Build' including our superflange.

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'.

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

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 here is one.

'Pre Loved' Rebuilt ARB RD128 24 Spline 3.54 CWP New ARB Air Coupling Clamp Kit Upgrade + Ultra Build and Built into Pegged Casing + NEW ARB Switch, Hose, Solenoid, Fittings

The ARB RD128 24 Spline (Current ARB Model). When these break they can be difficult to fix as if bad parts costs get up to close to a new Ashlocker, so sometimes we buy then in broken, sometimes in P/Ex, or even damaged, take all the useable parts and save them.

Now and again we decide to rummage through the boxes, and being honest here, sometimes we can build up a ARB etc from salvaged parts !. Hence we make up a nice cheap locker for someone on a budget. No, not top condition or top of the range but something VERY affordable, and as good as we can get it, and we are happy its good enough for us to sell. And this is one of those. Its a 'Bitsa ARB RD128'. Its been completely stripped, has lots of new parts like thrusts seals internal piston etc, and on this one even a new ARB Air coupling ring. No, its not mint, but its very cheap, and looked after will give good service. It's built into one of our Pegged Casings to protect the RD128s vunerable 'Centre Tube' - a very common and very expensive failure point when not pegged, oh, and it's our normal Ultra Build spec.

Air hold wise we have timed it on the bench, and it holds air for 58 seconds, after that a 1/2 sec buuuurrp, and another 58 seconds, which for any ARB is good lol.

So, your buying a well used RD128 loads of new bits 3.54 CWP and Pegged with new Hose, new Switch, new soleniod, new fittings. and, compared with some of the horrors we see that have been bought of ebay etc, and go up for sale for daft money this is a nice cheap solid locker. Pics show it all, also has our upgrade clamp kit fitted protects air pipe - another commoin ARB fail, and our stainless push foit ARB Upgrade.

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!

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.

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 Land Rover Standard 4.7:1 CWP for Long Nose Differentials

We are pleased to have also secured a supply of the trickier to obtain 4.7:1 Series LR CWPs. Again, these are Brand New / Old Stock, and at a sensible price.
£110 + VAT. Being the age used 4.7 units are, most are badly worn and finding a decent used one is at best 'Kin Tricky :D '.
These are in Stock and are sent out exceptionally well packaged for protection. We would however STRONGLY recommend 'Pegging' these to add a massive increase in strength, as the 4.7s are in fact weaker than the 3.54 units, having smaller and more teeth per unit !.

** 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 !

VERY Used Ashcroft 4.1 Ratio CWP - Aqua Blasted but 'Pitted' - Just £70 !

Ok, lets be very clear about this, it's a 4.1 Ashcroft CWP thats seen better days, if it was a standard gearset it would be an 'OWL' by now (see picture LOL). But it's not. It's a £250 Ashcroft CWP, it's been Aqua Blasted, looks superb, but has pitting. This doesn't really affect the strength, but it might, (or might not), be as noisey as ****. Until we build it we just won't know. Taken in P/Ex. it's a very cheap 4.1 for somebody who doesn't care about a bit of noise, or maybe not ?. Offered on any build or rebuild you choose with us. £70 for this vs £250 new. Ring to discuss . Nige :D )

Used 4.1 Ratio CWP - Maker unknown ! - £80 !

Well, this is odd !. We have purchased in a unknown make of 4.1 CWP !. It is most likely to be a Rover Umit from something, we are just not sure what. It basically has all the looks as characteristics of a 3.54 or 4.7 standard gearset, but we have triple checked and its defo a 4.1 !. It's NOT a HD unit, but pegged it would as with the other gear above give a very cheap solution for anyone looking for a double upgrade to 4.1s, rather than new Ashcrofts gears at £500 for the pair, this would be circa £80, so if you took both thats £140 the pair vs £500 new.

Is new better - Yes absolutely, but not everyone can afford the best at £500 for a Pair of New HD CWPs vs this maybe ?.
Offered on any build or rebuild you choose with us. Again, £70 for this. Condition is actually quite good ! Ring to discuss . Nige :D )

Used 4.7 KAM HD CWP - Only £100

This is a HD Used KAM 4.75 CWP, its agaiun been auqa blasted as it had not be overly loved, has some pitting but not too bad. The customer decided to downsize tyres and found it affected the performance too badly so we did a ratio change, taking this is P/Ex. Its in Fair to OK condition, no, not perfect, but it's only £100 vs £250 for a new one, so a significant saving !. Pics to follow.

Yes, its Used, Yes it has wear and pitting, No, it's not as good as a brand new £250 Ashcroft HD Unit - but not everyone can afford the best so here it is ready to go again !.
Offered on any build or rebuild you choose with us. Again, £100 for this. Condition is actually quite good ! Ring to discuss . Nige :D )

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 !!

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 !
