Just run your numbers through a gear calculator like the grimm jeeper one. Get it close to stock or deeper if you actually plan to wheel it.

I run 4.88's in my off road toy and wish I had 5.13's .

I would go with 4.56's if you are concerned about daily driving and gas mileage. However, it all depends on what your future plans are. If you get 37's down the road then you will wish you chose 4.88's.

I have got the same setup as you and went with 4.56s a week ago. Love my new gears. If you do a lot of highway,as i do, then go 4.56s, if not go 4.88s. As for the mpgs, my fuel consumption is much improved now!

The chart in the FAQ section has been fairly accurate from what I have seen and experienced.

4.56s for me too. Night and day difference from 3.21s. A fairly good crawl speed and decent torque for steep technical stuff Good power on the highway now too as u can actually pass people! My rig is my DD but sees a lot of trail usage and some highway commutes to get to trails in the lower mainland.

It was a toss up between 4.56 and 4.88s. I'm very pleased with my choice.

This chart is jk specific and 100% accurate. Helped me with my gear choice!
