PowerTrax No Slip

I installed my PoweTrax No-Slip auto locker in the the rear of my 00 XJ with the 8.25. I'm running a 3.5" RE superflex with 31" BFG MT's.

All I can say is WOW. The locker makes the Jeep a totally different animal. I was able to climb a 4ft vertical wall. Yes, My breakover wasn't good enough and I pivoted on my t-case x-member, but the ol XJ pulled through.

Installation was simple, except for the thrust washers. Dealer told me to re-install, instructions did not specify. PowerTrax said do not re-install. Cost is substantial compared to the LockRight, but on the street I can barely notice it, and off road it it amazing.

The lunch box type locker has always been considered too weak for the rear end:

Dude, he's running 31's. 31's with an 8.25 are fine with a lunchbox, as your very own link admits.

Personally I think that the notion of lunch box lockers as too weak for the rear is a myth with newer more modern lunch box lockers anyhow. I don't know about the PowerTrax, but I have an Aussie Locker. The four solid pieces of steel that make up this locker are stronger than the four spider gears that they replaced. The cross-pin is a wear item but will have no more force on it than it had in its original configuration. I wouldn't want it in the back (I can very definitely feel it surging in the front when I plop the Jeep into 4x4 mode), but as long as you check the cross-pin with every differential fluid change and swap it out once you start seeing wear, you'll be fine. I suspect that the myth of the lunch box too weak for a rear end dates back to early Detroit Locker lunchboxes. For my Aussie Locker, it's clear that the axle shafts are going to break long before the locker itself does.
