Default Gears

I just re-geared my 2 door with 5.13's. If you look around you can find some deals for around 1000.00 installed (in SOuthern California)

Check out Off Road Evolution in Fullerton. I'm pretty sure they still have their $1000 gear special.

i would say 4.88
unless you do some towing or live in hilly areas, then 5.13. and also a superchip to program engine better.
if you have a manual though, 4.88 would be the way to go.
i got the auto. no towing, not much hills. other then off roading. but i do drive alot so im trying to keep rpms down a little so i have better gas milage. but it would help if i can get the better performance. and i have been looking for a re programer and have been looking at the superchip. but still have a hard time to commit. trying not to spend more money then i need to.

I have a 07 X with manual. It came with 4.10 gears vise the stock 3.86. I was running 2800 RPMS at 65. I just lifted my jeep and put 35in BFGOODRICH all terrains. I used the AEV PROCAL module, now I am running 65 at 2300 RPM. Using a little less gas and hills well have to drop to 5th on long hills.

I disagree

Since, OP does not have a Rubi, this is a non-issue for this thread

I have 35’s and went with the 4.88’s because I do a lot of highway miles. The most common is the 4.88’s and the 5.13’s both are better than what you have now. You can use 5.38’s just don’t drive 90+ mph on the freeway.
