Ashcroft LT230 ATB Diff

Does anyone have any experience with one of these?

Ashcroft Transmissions

I've read it can minimize drivetrain slop and can help on low friction surfaces...but I don't have open diff front and rear, I have a Detroit locker in the back and a truetrac LSD in the front and I can't seem to find much about that combination of front/center/rear.

My worry is that the Detroit in the rear may cause a little too much drivetrain windup for some reason...but part of me thinks this wouldn't be a factor because the front wheels travel farther than the rear

I understand how a limited slip diff works between two axles but my brain starts to hurt with four axles, two driveshafts, another LSD, and a mechanical locker. Anyone who can shed light on the idea would be appreciated.

It's for a '94 D90 and I'm looking to reduce drivetrain slop and reduce wheel spin with an unlocked center diff on sand.

Dio you have any resolution to your question? Iam looking at this automatic torque biasing centre differential option for my 1990 110 with factory diffs and LS engine. Maybe trutrac later on

I've got that LT230 with ATB. I've also got Detroit trutracs front and rear. Can't comment on the Detroit locker in the rear. The combination I have is really smooth though.

I've got that combination sitting on my garage floor waiting to go in. I have KAM locking front and rear. That all being said I can't really offer up any feedback until I actually get the thing going

Interesting idea. It seems a bit like the BW box on RRC yet remains manually lockable as well.
I have a Detroit on my truck. Tend to drive with the center diff open unless at an obstacle which suggests a little extra caution/traction is desired.
If I had a BW box on a RRC would I worry about a Detroit in the rear? I doubt it.

I found reading the description on their Web site good, from it I take the the ATB works as a Saftey if you happen to hit a icing spot with one wheel and it spins out control.

Still looking for that place where I can carry a paddle and get asked what's that.
