New Ashcroft 4 Pin Center + 3.54 Dana CWP in late Puma 'colletted' Casing with 'Domex 700MC Carrier Cap' upgrade - S/N : PC1090

The last of the PUMA casings (this one here) had both good and bad points :
The 'Good' were the collets which connect the carrier caps to the main casing - the Bad was very bad and are the daft hollow 3mm roll pins holding the entire differential together on the sides !. They break and your diff 'Unwinds' and then explodes !

We like the collets, we do NOT like the silly roll pins - so we convert the Carrier Caps to our upgraded version which then sorts not only this issue completely, but makes then for a seriously strong unit.

And thats what we have here, a late PUMA differential with a beautiful Dana CWP which we have stripped cleaned to within an inch of its new life, upgraded the Carrier Caps to our Domex 700MC upgrade, added a brand new 4 pin Ashcroft centre and with a full ultra build spec and Superflange upgrade this is good to go !.

A really really good solid strong upgrade without breaking the bank (too much lol ) Just look at the pictures :O)

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

New Ashcroft 4 Pin Center + 3.54 Dana CWP in late Puma 'colletted' Casing with 'Domex 700MC Carrier Cap' upgrade - S/N : 2026

You might notice this is a 2nd of these units - we built them for a customer who then decided he wanted pegged units and HD CWPs so these became stock, which is rare at the moment as we are so busy, but here is No 2 . !

Brand spanking new KAM Differentials Plated 'LSD' (Limited Slip Differential) 'Build Your Own Event' !

Well this is a bit of a one off post - haven't ever done something this in the 15 years of Diff building ! ............

You may have seen that we bought in a huge stock of brand new old stock KAM Differentials parts, including a large number of the fabulous 4 Pin centers ... and even tastier..... KAM Limited Slip Differential Centers - with one piece 'forged cross shafts'

Now, these LSD centers are the earlier ones which were IMHO the best that KAM ever made, even now ( more so being brand new ) - I would say these are STILL the best plated LSDs that money can buy. Rather than having them just sit on the shelf I have had a little idea.

Below is a listing of all the possible ways these can be built. If you fancy one or even a pair, then you can 'Pre Order' - there will be a 4-5 weeks build delay as these will be built to order.
We can also lower the clamping force if you would like for a slightly softer "Front" LSD - but rather than digress - ring and chat

One of the drawbacks on these KAM LSDs is the parts availability. Whilst we have had a stock of plates etc, but the stock is near gone.

The really brilliant additional news to the above is we now have the original CNC / DXF files for all the above, so we will shortly be taking stock of new LSD Plates and other parts, meaning we will be able to replace worn friction and separator plates etc if these ever need in the future - or for any already out there.!
It's something we have thought about for a long time, but we have decided to go ahead and invest in spares as the demand for these units both new and existing is very strong. These LSDs are super strong, way way over engineered, and we rarely see any broken, they are beautifully engineered, and, these being early units are 'LSD Plated' on BOTH sides of the 2 x 24 spline drive gears.

Also..... even though they are brand new ..... we have / will be stripping them completely, ultrasonic cleaning oiling and then rebuilding as in the pictures below. If you fancy one / pair of these then grab soon - as these we know will be snapped up, by those who know what they are, how good they are, and rate them. !

Once we get down to single figures remaining we will add a warning note to the webshop, .....but for now we can say we have "Good Stock" !!

So, your options are : (Oh and we will not be selling these 'Unpegged' or with 'Standard CW&P's - Top End centers need Top End builds !)

New Ashcroft ATB Center + New 3.54 Antonio Maserio CWP in early (stronger) Casing

This is a particularly super example, just check out the blue print - 'Textbook'.
Some differential builds are ok, some are good / very good, and like this one some really REALLY good.!

This is a Brand New Ashcroft ATB (A Limited Slip Differential - but it works via Gears not plates) - so no special oils etc, pretty much fit and (other than oil changes) forget.
It has a Brand new Italian 'Antonio Maserio' Crown wheel and Pinion in standard 3.54 Ratio, just look at the rear face of this unit - its a polished finish - its the quality of the CWP that helped make it such a superb finished unit. We have also built it up into a earlier casing - these have the huge steel (our own make) locking ears to hold the adjuster rings in place - which is essential. The later casing dropped these reinforment ears for daft weak hollow pins, which fall out / break / bend and thus damage you diff. With an ATB the diff works harder than a open standard unit - so hence why a stronger casing.

All in all a beauty !

Price, as with all our Differentials is a OUTRIGHT Cost - ie NO Surcharges, NO Exchange Costs. You fancy a really nice new ATB ? - You've just found it.

Xcess 4x4 'Tab_Lock' Upgrades for Ashcroft 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 Transmissions, is we, machine 'End Flanges' of 'Ashlockers' 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 torqued up 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 £138 for the Ashlocker (Exchange), or a bit more if supplied new no exchange.

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

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

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

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

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

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

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

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

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