All about the gears
I have a 07 Jk 2 door X edition on 35's, a 4 inch skyjacker lift,with 3:21 gears. What would be the best gear ratio to get back my fuel economy as it is an 80 percent daily driver, but still have the power to do some mild trail/rock crawling every now and then? Thanks

For an auto, the 5:13's are best for performance but I stayed with a 4:88 because of my concern about pinion gear size: It's relatively flat where I live and rarely tow anything.

Held up fine, I was just careful.
And yes it was tiny, you could see the bearing behind it.

In '07, the gear choices from the factory were 3.21 and 4.10. Since you haven't mentioned the lack of power now, is it possible you have 4.10s in it now?

I'm gettin' ready to do new tires and wheels next month and have been scouring the forums for input. I'm in an 09 6sp with 3:73's and have been tossing up 33's vs 35's .. Obviously, 35's is the choice that i WANT, but I also don't want to destroy my rig or the fun of driving it. I'd be tuning it up with a programmer immediately as i've seen where that helps some. Any of you guys running that set up?
I've seen it go both ways... Some people say it's horrendous, some say it's just fine.. Re-gearing at some point is almost always recommended from both points of view, of course... and i'd do that some day when money allows.. Just wanna make sure i'd be "ok" until then!!
