Your auto trans has such a deep overdrive that you can't possibly gear your Jeep too low. 5.13 is the lowest gears you can get for your Dana 30, and with 33" tires that is going to be just right. I've got 5.38 gears in my auto two door, with 35" tires, and I think it could stand to be geared even a little lower, if they made a lower gear set. These things are such DOGS that you need the low gears. You'll even get better gas mileage with lower gearing, because your tranny wont be downshifting to second gear every time you need to go over a freeway overpass.
