IF you don't plan on wheeling it hard you might want to look at 5.38s. With the 42RLE auto trans in the 3.8 powered JK having such a tall overdrive gear, even 5.13s can be unbearable when you get into hilly terrain. 5.38 gears have a really small pinion gear though and can be a weak point if you intend to wheel it hard on 37s. It'll be a pretty rough 6 months driving on 37s and stock gears for 6 months. You can make it work, but it'll suck. Do you have 3.73 gears or 3.21?
