I have a 93 YJ with a stock 4.0/ax-15/np-231 drivetrain. I recently aquired 35" all terrains at a cheap price. What I want to know is if swapping a 4.10 rear end from a four banger will turn 35's? Will I need to regear the front as well? I won't be doing very much crawling but will be climbing hills and bogging as well as some road driving.
