Your 2002 has a 3-speed automatic, 4.56 would be too low for 33" tires if you drive it on the highway. You'd be doing 3000 rpms at 60 mph. I'd go for 4.10 with that transmission and tire size if it were me.

rketr X2 4.10's or, if you offroad any, 4.56's.

Jerry Bransford Well, your engine isn't running all that efficiently (rpms are below the power band) and odds are you could boost its mpg a tad by regearing it to the correct ratio. But how long would it take to recoupe the approx. $1200 cost to regear by a couple mpg improvement?

That said, I would regear anyway. With your 3-speed automatic and 33" tires, 4.10 would be a very good all-around ratio.

jgano23 i don't really think much can be done for the poor mpg's. 05GT-O.C.D said it best:

4Jeepn What are your stock gears? As for MPG figures I had 35's and 4.56's, 5spd and got about 12-14 mpg.

Question about regearing

i have a 2002 sahara with stock gears and auto trans. Im am currently running 33's on a 4" lift and was wondering if i should regear it. I dont care about getting more power, i just want more mpg. Would regearing to 4.56's benefit my mileage?
