I have an ARB locker in the front and will be installing one in the back in a couple of weeks. I don't want to change the gears due to the cost and lack of experience with gear install and setup.


Since you are all ready have lockers(rear soon) I would just run the 4.88's and mod the engine some.

More than tread lightly. Leave it like you were never there, nor anyone else.
