powertrax locker

Has anyone had experience with this locker? I want to install one in the rear of my wrangler and am wondering about the on road/off road handling characteristics as well as durability. I have a detroit locker in my CJ and like it a lot except for the 1/4 turn of slop in the driveline when I go from park to a gear. The CJ is an automatic so the only time I even know the detroit is there is when I first put it in gear. However, the wrangler will be a stick, so I want it to be a little smoother.

Re: powertrax locker

I installed the Powertrax in my 85 CJ7 last summer. Within two weeks both axle seals started leaking. This was annoying but it was a good excuse to replace the two piece axles with new strong one piece axles.

The locker works very nicely. There is a little bit more differential noise than before and there was some annoying clicking for the first few hundred miles. But now it's quiet and operates smoothly. Of course there is the typical torque steer that you get in a short wheel base vehicle with a lot of torque, but you get used to that and compensate in your driving. This is because when turning, the inside wheel has the power instead of the outside wheel as in a open differential.

Off road it works great, sometimes in mild conditions I'm even tempted not to engage 4wd! The most improvement that I have noticed is on wet highways, I used to have to be very careful when starting out at a traffic light, it was very easy to get one of the rear tires spinning. With the Powertrax locked, there is just a lot of grip, the CJ just goes!

Hope this helps.
