Gear Setup

Before I slap all of the axles back together. I am wondering how my CJ will roll down the road with a 232, T5 trans, AMC 20 with 2.72 gears??

I wanted to run 30" tires on it???

The jeep will be a daily driver on the highway, with some occasional off-roading (mild)

Well, being that I have a jeepspeed racer xj.. No not the ones that kids put a nerf bar and larger tires on and call it a jeepspeed.

Mine is SCORE and BITD approved.. Gearing is so important. In my opinion, I would get your gears to 3:73 or 4:10. You want to run 30's and at some point if you get larger tires, it will help.

I am running 33x10.50. Had 4:56 but finally went to 5:13 and feels fantastic. But again, mine is built for racing.

Good luck.

Rather than guessing or letting other people guess for you, plug your information into the below link and determine what your engine RPMs will be at a given speed and determine if that will work for you.

Gear Ratio Calculator

For mostly highway driving the 30" tires and 2.73s will probably work well. You may not be able to use fifth gear on inclines, but it isn't a terrible combination.

Racing is quite different and so is the torque curve of the 232 vs. the 4.0 found in an XJ.

With a T-5 and that tire size, the motor will be more comfortable in the 3.31-3.54 range.
