I'm going to ask politely that you all please keep this specific thread on topic.

Any tangents and deliberate off topic posts will be deleted without warning.

If you dont like this then please dont post

Im sorry, but of the Ashcroft threads I have read all talk was relevant to the topic, whether it be the Ashcroft locker (and people wanting a Sals version) or the P38 type rear diff thread and varrious ideas and opinions being posted to see a bigger picture.

Maybe the confusion is coming from those calling P38 diffs, Rover type or being months behind the 8 ball on already discussed topics.

Ashcroft have a fantastic reputation for customer service. If I was serious about purchasing an upgrade for any of my rover stuff, and I was capable of posting on the Internet, I would probably email, or even yet phone Ashcroft to get up to date correct info.......

Now is the OP confused and thinks the "maybe" P38 diff upgrade is a Rover type upgrade/ Or does he mean the "Force 9" which IS designed around the rover housing?

I havent seen anything posted on a whole new 3rd member for the Rover type housing, I couldnt see it making sense with everything else they already produce???

I have been wrong before though.

cheers,
Serg

If I had a spare $13000 or $14000 and wanted to build a comp truck I would most definitely slot in the Force9 setup. But I don't......

yes but we need clarification....Is it the Rover type diff? these can be built plenty strong enough (Using Ascroft locker and HD R&P, plus various brand axles and a few different brand cvs) for any LR tourer. Or is it actually the P38 type in question???

I would say looking at the OP's avatar he is talking about the P38 type.

This new diff centre is not the Force 9

From what I have read the replacement will need a complete new housing for the CW/P gears as the current Rover version has a problem with the bearing spacing on the pinion, allowing it to flex - causing the weakness.

I am with TimNZ on this, Dave you know you want to and I know that you can sell at least one straight away.

As I said, I could be wrong, but what you are describing is the discussion on the P38 type rear diff as fitted to late model 110 and 130. Not only is it the close bearing spacing on the pinion, but the thin Ring gear.

People have also been referring to the P38 type rear diff as the "Puma" diff, giving more confusion! first of all Puma is a bloody engine code name, and 2nd the P38 type diff is only found in the REAR of 110 and 130, all front and 90 rear diffs are Rover type

Slunnie, Im not sure if you know already, but keith from Rovingtracks has done this already. He was contracted by the UK Mil to do some HD complete axle set ups. From my memory he used specaial made 44 housings for the front. The UK took order of his rears, but ran out of money for his front design. Ill see If I can chase up more info for you.

Very good idea, esp since you can get 3.54 Dana 44 gear sets.

Seems an obvious way to go

That Force9 reminds me of a ford 9" but built for a tank!

The Force 9 was originaly based on the Ford 9 inch diff, but due to problems Ashcroft found with it, they designed their own R&P to suit their needs.

There are many aftermarket Ford nine upgrades Diff wise in the USA. Even a HD hi pinion unit called the Tru-Hi9
