Re: What gear ratio with 33\'s
I run 4.56's with my 78 CJ5 304 D20. It is just a little under geared, like I need to shift one more time (no overdrive). I plan on putting a Tera kit(3.15)into the D20 so I can put a little taller set of gears in the axles to regain some of the lost highway speed/rpm. My 94 YJ 2.5 came with 4.10's but it has an overdrive and 31's.
I would recommend that you look at the entire drive train as well as the tire size and then decide what gears to run.
