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

New Ashcroft ATB 24 Spline + Pegged Casing + New Ashcroft 3.54:1 Ratio CWP

ATBs (Basically a 'Limited Slip Differential' via Gears vs Plates) are proving very popular as a fit and forget upgrade with additional traction Differential. Additionally, being gears vs plates ordinary EP90 oil is used vs the expensive LSD plate oil.

These units are very strong too, and this unit benifits from one of our new 'Pegged Casings' and a brand new Ashcroft Crown Wheel and Pinion, with a full 'Ultra Build Spec' - including 'Superflange Conversion'. More information on how these work if your curious to know can be found in the 'A-Z of Land Rover Differentials page'.Interestingly, even if you have a late Puma with TC - 'Traction Control', these units will work in conjunction with the 'TC' system, giving an exponentail level of additional grip and traction !

'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 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 !.

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

These are loved or loathed, you decide, but they will give you hands free improved traction over any open differential. Ultra Build Spec and Pegged too.

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 !.

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 !.

'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.

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.

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 Preloved Ashcroft 3.75 Ratio CWP

Ok, Its not the nicest CWP, lets be very clear about this, this is a Ashcroft 3.75 CWP thats seen better days, if it was a standard gearset it would be an 'OWL' by now.... But it's not. New it's a £250 Ashcroft CWP, but has LOTS of pitting.

This doesn't really affect the strength, but it might, (or might not), be as noisey as ****. Until we / you / someone builds it we just won't know. It's a cheap 3.75 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

Buy either ONE or a PAIR of Preloved 4.1 Ratio CWP - Maker unknown !

Well, this is odd !. We have purchased in a PAIR of unknown make of 4.1 CWPs !.

They are most likely to be a Rover Unit from something, we are just not sure what. They basically have 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 !. NOTE these are NOT a HD units, however pegged they would, give a very cheap solution for anyone looking to go 4.1s for a single or double upgrades, vs new Ashcrofts HD gears at near £500 a pair, not everyone can justify or indeed afford to buy new, so here this is as a option. In pretty good condition - as you can see from the pictures, but, being 2nd hand we cannot guarantee that they may not be as quiet as new gears .....

This is a HD Pre Loved KAM 4.75 CWP, has a little bit of pitting but not too bad at all for a used unit. The customer decided to downsize tyres as he found with small tyres he had gone too far LOL..so we did a ratio change, taking this is P/Ex

Yes, it's used, yes it has wear and a little bit of pitting, No, it's not as good as a brand new £250 Ashcroft HD Unit - but not everyone can afford the best / or brand new ... so here it is ready to go again !.

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

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

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 !
