  • Gearing help

    I'm getting ready to upgrade to new ARB lockers f/b on my 01 jeep with Auto tran but still don't know which gear size I should drop in I have 3.73
    now on 33" tires so my question is:

    should I put 4.10 or 4.56 on a 3 speed auto tranny with D30 front, d44 rear

    Thanks for any opinion

    I use a manual tranny, but for the 33's I have on my jeep, the 4.10s are not deep enough (even with the 4:1 t-case). Automatics are a little more forgiving when it comes to gearing though.....

    It really depends on what you do with your jeep. If you spend alot of time on the freeway, the 4.10's are nice for fuel economy, particularly with the automatic. But if you don't spend much time there, 4.56's will give you more control off road (at the expense of fuel economy and top speed). Also look down the road....are 35's in your future? Even if you do the labor yourself, component costs add up if you have to do something more than once.
    olllllllo <--- If you can read that, roll me over!

    Price is soon forgotton, quality is not.

      I have a CJ with 33 and 3.73. I plan on regearing with 4.27, kind-of a trade off

        I have 33" and 4.56 but a 5spd in my 98 TJ. A bit of warning, my gas mileage sucks now but I love the power of the 4.56s.

        If you plan on going to 35s like goodtimes mentioned, then I would go with the 4.56.
