The Ashcroft 4 pin is a strong unit with its 18mm cross shafts, but made even stronger with our upgrade of the 3 x cross shafts and center boss to a 1 piece forged cross shaft. In all the years we have had these, plus my years at KAM differentials- I have never EVER seen one of these broken !. On top of this we have also CNC machined our popular and super strong 'Tablock' upgrade in the casing. (If you are unsire what this add strength wise have a look at the tablock Menu tab.)

We carry limited stocks of these - if it shows as 'Resereved' then we have stock, if not it will show 'out of stock'

New Ashcroft 4 Pin Center with new 3.54 Dana CWP in late Puma Colletted Casing with Domex 700MC Carrier Cap upgrade

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 with new 3.54 Dana CWP in late Puma Colletted Casing with Domex 700MC Carrier Cap upgrade

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 . !

Build Your Own Brand spanking new KAM Limited Slip Differentials from our brand new old stock we have sourced

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 with New 4.75 Front Cut Reverse Rotation HD CWP in New Pegged Casing

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.
This was build for a customer who ran just after finsihing building the 2nd of his 2 x differential orders, he asked to change this to a High Grade 4 pin unit ...Argh...

We decided that we would leave this as is, and pop on the webshop, and then we built / or is that rebuilt (?) lol - his 2nd order. So here it is !.
When / If we get time we may build up a matched unit for a Rear Axle, and offer these as a pair. 2 x ATBs can be absolutely unbelivable vs standard open diffs, problem is we are so busy unsure when this might be - so listing this 'as is' in meantime !.

It has a Brand new HD 'Reverse Cut / Front Rotation' Crown wheel and Pinion (See section in our FAQs that will explain this - but do NOT buy this and fit into a rear axle casing !.) We have also built it up into one of our Pegged Casings, with a Brand New Ashcroft ATB - 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 TabLock 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.

This is some build - avaialble with or without the additional new hose switchgear fittings soleniod etc, which if required is just an extra £30
