Eaton Truetrac Diff, Anyone Running This???

I work at Weddle Industries, we specialize in off road racing transaxles and VW transaxles. I am a trans builder and sales guy. My wife's daily driver is a 2008 JKU "X" with 33" Toyo's.

http://www.weddleindustries.com/

We do all of the services on Albins transaxles which use a planetary differential (AKA: Automatic Torque Biasing diff) which does not use any type of clutches or dog-ring engagement that most limited slip diffs utilize, which eventually wear and need servicing. We also sell planetary diffs for VW type 2 transaxles for the guys that take their camper and Syncro 4wd vanagons off road or drive in the snow.

The idea is the diff will evenly distribute power to both wheels under acceleration in low traction conditions (sand, gravel, mud, snow), but will still allow both wheels to turn at different speed when cornering on the street. We often go to the sand dunes (Pismo, Glamis, Dumont) and I like how these diffs work in our applications at Weddle Industries, I've sold many of them and customers like them. Since we don't do any rock crawling, I don't need any type of full locking diff since all wheels will be on the ground.

I've really only been able to find these Eaton diffs which look nice, but I want to hear if anyone if using them and what your thoughts are or if there is another manufacture out there.

Thanks for your input.

No personal experience, but I've heard nothing but great things on them.

This is the problem, when you do a search, there is too much information out there. I'm looking for real world advice from people who are using them. I dont have the time or patience to filter through pages of BS on google.

Fourwheeler magazine rated them as the best thing this side of a locker.

I'm running one in the rear. Hard to say how well it works because if it's doing its job you forget it's there.

Outside of off road I can certainly tell a difference in snow and rain.

Ran them front and rear on my LJ. Everyone thought I was locked. Great on snow too. Only place they dont shine is extreme rock crawling where you likely have tires off the ground regularly. One tire off the ground the other two should keep you moving. If i upgrade my JK axles I will install them again. Great great great LSD

Here they are in action. From this angle its hard to tell but this was a very steep, rocky hill with lots of loose stone and sand.

I have a TruTrac up front and it's awesome. I only use my rear e-locker to make sure it works still, haha. It really is seamless, you don't feel a kick or anything.

Front and rear and they work very well and seamless.

If the tire lifts they will spin a little but then the bias kicks in and away you go.

Thanks everyone for the replies. That's exactly what I needed to know.

It will be awhile before I get them as I am going to do 4.56's as well. I'll probably just do the rear since I am really only using it in sand.
