thanks for the info guys it makes sense now
, heres the story; I just put 35's on my '10JK w/3.73's-d30 front, d44 rear, I want to put 4.88's, the shop said they could use the exsisting carriers w/ a thicker cut gear, now my question is this- when I put a locker in the rear in the future, will I have to replace the gear again? I think I can get a locker that will accept the thick cut gear correct? I would like a tru-trac up front and a selectable in the rear, ideally i would do it all at once but i don't see the bank account agreeing with that...
