So ive got 3.07 gears and 33" tires and a 4"lift.. this is the way i bought the jeep. It dont really seem doggie..i haven't done much off roading yet and probably wont start till i pay off the jeep...with that being said,.. its a manual 4.0 with 85k.. should i be concerned with the rear end in this thing? And if so, i see alot about the ford 8.8? Is this a good conversion and what would you do to the front end to make it work??
