I see that you're going with 33's so you should probably pass on the lock-rite or powertrax no-slip. I had a lock-rite in my Isuzu Rodeo when I was running 33's and I broke the sheer pins quite a few times, plus the truck had a manual tranny and it sucked when I shifted at freeway speeds (passing and what not) as it would disengage the locker then as soon as I shifted and pressed the gas the locker would engage and the truck would want to veer to one side or another. Took some time to get used to, but maybe it was my truck. I think that if you're going larger than 32's you run the risk of breaking the sheer pins depending how aggressively you wheel. I currently have a powertrax no-slip in the rear of my ZJ with 32's going on 2 years now and have wheeled it as aggressively if not more than my old Rodeo when it had 33's and haven't had any problems yet. Something to consider...
