    What engine do you have? If its a v8 I'd recommend for 4.56 for a v6 maybe 4.88.

    i would say 4:56 or 4:88 if not too much freway driving as most charts show the 4:56 is a great 35" tire gear...mike

    Need more info, What engine, Manual or Auto, Aluminum or steel wheels. That chart does not allow for weight of vehicle or wheels. To play it safe, I'd go with 4.88 (assuming that its an auto tranny).

    Just did my brother's jeep this past weekend he put 35" tires, and we geared it to 4.88.

    My 2003 Jeep 4.0 I6 5 spd is geard with 4.56 running on 33's and its my DD
    My 1976 Jeep CJ5 is on 38's and geard with 5.13's -- it's only used as a trail rig

    ****VERY IMPORTANT****
    IF IT IS A 4x4 YOU MUST GEAR THE FRONT AXELTHE SAME AS THE REAR

    If not, bye bye Transfer Case

    PS: When you buy the gars, do yourself a favor, and spend the extra $$ on Yukon Gears -- they are a lot better thatn Genuine Gear, Alloy USA, or Superior Axel and Gear. Trust me, I have broken just about every ring gear out there and the yukons do not break
