There is quite a lot of different names banded about. Have a look at the Ashcroft transmissions website. They have a page on diffs which has a lot of good info.Yeah sorry not very well written, I ment the diffs. I think il have a quick look at wot I said about fabbing the turrets but I ain't holding my breath, would be good to make use out of the left over parts...and save a few quid tho.
I don't know which diffs are locked but then click when turning tight, and which ones are basically open until the time arises and they are 'set off' sort of thing. I've heard detroit truetrac being mentioned as good but is detroit locker the same thing?
Cheers

Yeah, Detroit locker for the rear, Detroit True Trac for the front. Basically they're usually off, and work as an open diff but the mechanism inside works when there's a wheel speed difference and they tighten up until they lock. The clicking, sometimes banging, is when they 'let go' coming out of the corner that's made them lock up, to release the tension.
True trac is similar but different and more applicable to fronts, it's more of a limited slip than a locking diff, never reaching full diff lockup, hence it's front bias. Don't put a Detroit on the front, you'll have trouble in the corners with the steering basically washing out and carrying straight on!
They can be fooled into locking by spinning up the revs and left foot braking, but don't need tricks as they work with a difference in wheel speed, so any slip off-road makes them lock.
“Detroit” is a brand/make of diffs. Their True-Trac is an ATB. But will cost more than an Ashcroft ATB.
The “Detroit locker” is something different entirely. The brand is still Detroit. This really belongs in the first camp as a full locker. Although it’s name is misleading. It is actually an automatic unlocking diff. This means it is locked in normal use. And unlocks when it detects you are cornering at speed. It is fully mechanical and durable. But suits heavier longer wheel base vehciles the most. And can feel a bit odd on road as it unlocks and locks again. And while it can be run in a front axle, normally lends itself better to the rear, non steering axle due to its unlocking/locking behaviour.
I always thought the Detroits were effectiely an open diff that locked up fully with different wheel speeds and unlocked as speeds evened out again.
This vid explains better than I can. It is speed sensing. So it’s locked nearly all the time. Only cornering on high traction surfaces will it unlock.I always thought the Detroits were effectiely an open diff that locked up fully with different wheel speeds and unlocked as speeds evened out again.

Yep true Trac is an ATB. The Ashcroft is arguably a better designed. As Ashcroft looked at the weak points of the true Trac.
Good info here. Make sure you view the desktop version. Not the mobile version of the site. The latter doesn’t have the text.

Thanks for the link
At that price point they aren't a dream or fantasy are they, they are a realistic option for many people, and from a company like ashcroft they should work well aswell which is just the icing on the cake
Well I've always said that I would like one, but I thought I would end up with a truetrac, so have yours needed any repairs or maintenance in the 10 years then?
