    Now that I have my huge tires, I want to swap out my G80 for something better. I was wondering what to go with? An Eaton Tru-Trac, EZ Locker, or the LSD. I'm going with 4.56s and want to get some info for later as well. When I upgrade my transmission what stall speed should I go with to compliment everything else? Thanks guys, everyone has been super helpful.

    I'm sure any of the mentioned diffs are good. I've had pretty good success with the Auburns. They eventually wear out though, cones and not rebuildable. For $125 they send you a new unit if you burn it up in the first four years from purchase.

    What i really need to know i guess, is what is the difference between limited slip differentials, and automatic lockers?
