    Question Who is running 4.56 gears on 32's??????

    I want to know who out there is running 32" tires on 4.56 gears.

    After you put on your tires and gears, did you notice more low end power than you had before?


    I am going to be adding a 3.5" lift and 32" tires. To go with the tires, so I am going to be getting new gears all around.

    --What I want from changing the gears is more low end power than what I have with stock tires and 3.73's on a V8.


    Please give me some input.

    Torque wise the 4.56's and 32's will put you back to factory. Maybe 100rpm higher on the highway.

    my friend is running 4.56 gears with 33 SSR(more like 34in) and he seem to have the same power if not a bit more then when his Zj was stock. He has a 4.0 liter. if yours is a 5.2 v8 you will be fine. i plan on running 4.10 with my 32's or 33's and i have a V8. hope this helped.

    I'm running 33s and 4.56. I can't see why people would want anything less. This seems to bring it right back into range. BTW: My speedo is dead on - no change needed.

    4.56's do well for 32" tires and steel rims. When I ran my 32" Swamper SX's and steel rims, it almost felt like I lost some power over stock, but then again those tires weigh a lot. I wouldn't go with less than 4.56 for 32's or higher. I do run quite a bit of RPM's on the highway with 4.56's and 31's though.

    My 32"'s measure more like 31", and with the added weight of the armor and bumpers, roof rack etc, and a 4.0L, the 4.56 make it bearable. I wouldn't settle for anything less than 4.56 for 32".

    Your crawl in low range will impress you for an automatic.
