The one in the transfer case or the axles?

I have seen a review for the T case one on AULRO and Buckon37s posted some information on the Pirate4x4 bulletin board. I want one.

I have them in both axels with no issues. They will pull a bit if your tire pressure is different left to right. Works great in the snow and mud. What would you like to know?

Just looking for impressions. I do not want to do regular lockers on this truck and thought these might be nice?

There was a lengthy thread on the relative merits and impressions of the various diffs last year. the issue boils down to extremes. The hardcore crowd says nothing but air lockers. The pragmatists like the practicality of the automatic limited slip diffs. For me, I have virtually no negative effects with the ATBs, they require no driver input (unless one wheel is off the ground), and they work for the 95th percentile of situations I would encounter (the winch covers the other 5).

My recommendation, unless you are one of the hardcore offroaders, get the LSDs or TTs.

Yep I agree with you. I have the air lockers on the trail truck and have known people with TT's for trail trucks. But these are not going on a trail truck. I was more interested in getting a 4 pin diff for the strength. In reading Ashcrofts sales pitch there ATB sounds pretty good plus the price wasn't that much more than just the 4 pin diff. They even have addresses the cross axle problems?

sold those things vowed not to get auto diffs ever again.

Carlos, thanks for the comment. I have heard other stories like that with the TT's and then other people love them. I was wondering how much different, at all, the Ashcrofts would be? Probable about the same I would guess.

Mike,

The Ashcrofts work differently that the TTs. They are a 6:1 bias torque biasing differential and don't "lock" like a True-Trac. I have driven them in snow and mud and notice no unusual tendencies (I have them on both ends). The only issue is the torque steering if there is tire pressure differential on dry pavement, and having to dab the brakes if I am cross axle. I have not tried traversing on a slippery slope, so perhaps they may behave similarly then, but I don't think so.

I've never experienced the same scenario but certainly see how that can happen. In snow and slick mud I don't run the cd. I run a tt in front and Detroit in the rear. I'd give Bill at Gbr a call. He's good people and will not try to sell you shit you don't need.

I'm not rolling hard core like Clay, but I can't say enough about the True-Trac (made in USA) in the rear. Front remains open. It just works and the additional traction over an open rear is significant. There is no adverse conditions, nose, clatter, etc. Tooled all over the local field/trail/hills with >>2 feet of snow (KM2s aired down to 15psi) this Feb, surrey and all. No problems, but haven't tried icy conditions (nor will I).

The Ashcroft units are better designed and, more importantly, have much better customer service. Eaton is horrid to deal with.

While I have only driven open difs in the snow, all the research I could find on the TT was that they behaved very well in the snow. The Detroit locker was a different story however.

Detroits and trueteacs are fine in the snow and ice.
