So... I'm about to add 35's to my '09 JKU Sahara auto w/ 3.73's, and from what I've read here, I will probably want to regear. My plan initially is to try it without, but I'm guessing it will be sluggish with 3.73 and auto. I should note that its my DD, and sees very little mud (occasional dirt roads hunting) and absolutely no rocks (its NW Florida). I may go to 37's or bigger eventually (may be quite a while), so I'm thinkin' 5.13's. I have no plans to do the regear myself. Should I find a shop and let them get the gears or should I buy gears and have them installed? If I buy, what else will I need to buy for regearing besides gears? Its only got 38k miles and probably never seen mud (I just bought it used) so I'm guessing I don't need master overhaul kits.

Any thoughts, recommendations, advice, etc.?

I had an 09 with 35's in Tallahassee with 3.73 gears and had no problems. I kept OD off on the interstate and it was fine. Only other mods were an intake and superchip. Now I run a 2013 Rubicon with 410's and 35's. both were fine. If you need 4th gear then go 513's. I didn't travel to far so it was never a big deal.
