Todd, I don't know what your going to use , but I just put a powertrax no-slip in my car, it gives you the full locker, but will disengage when turning, really a sweet unit, gives you the best of both worlds, pretty easy install, about 2 hours for me, I have never had the back off a differential before
so it may take someone more experienced less time, from what I've read these are top of the line units!!
