Getting ready to regear the Jeep. Eaton e locker up front with 4.88 gears. Now since I drive a lot in snow and deep snow being in the northeast I want a rear lsd. It looks like there are two options. One being the Eaton tru trac and the other being the Yukon duragrip positraction which uses a clutch pack. Does anyone have experience with one or the other or someone that could explain why one is better. Hopefully this topic has not been beaten to death already.

 

For offroad use, lots of folks consider gear-driven LSD's to be superior to any of the clutch-based versions due to the tendency of the clutches to wear out quicker. (yes the clutches can be replaced, but that requires opening up the axles again if/when they self-destruct). So between those two, Truetrac gets my vote. A newer geared lsd to consider is the Powertrax GripPro. Haven't seen any reviews of it, but at least there is some competition for the TT now.

I ran front/rear truetracs for many years (swapped out a pair of detroit lockers for them). For my usage, they were great offroad, and much better than full lockers onroad - especially on slick mountain roads through Colorado winters.

 

My experience with clutch type limited slip diffs (rear) is that they tend to get squirly in a sharp turn on icy streets. Haven't used a tru-trac, so no first hand comparison.

 

I would use either. In fact I am thinking of building up a Dana 60 junkyard Ford 3/4 ton diff 4.10 with 4 pinion clutch posi for my Jeep now it is V8 powered and dump the Rubicon diff. If I am out wheeling and it slips and makes an obstacle stop me I will do one of two things - get the winch going or go home.
BTW fellow Jeepers - I am in New Zealand writing this response and I am so pissed at seeing all the CRD 2.8 Jeeps here. Everything is diesel including Raptor Ford Rangers and every other pickup under the sun here.

 

Thanks for the info so far guys. Looks like I’m leaning towards the trutrac for now.

 

tru-trac would be my choice as well.
Have seen the Powertrax GripPro advertised, but have no hands on experience with them.

 

Only heard good things on Truetrac but I do think they have a limit on tire sizes they want you to watch....

 

The tire size limitation is 38". It was raised 10 or 12 years ago.

 

I just added a Dayton Tru Track to front of our JK. I am a fan. Works well and no clutch pack to worry about. They do make one for the rear. This is a proven product that works well on thousands on Humvee's.

 

After using both types I prefer the TT. On very slick roads the clutched unit will tend to understeer, more like a locker. I found the clutch type unit transfers far less torque when you try to fool it by adding some brake.
