I apologize, since I’m sure this question has been asked thousands of times, but I get mixed answers and I’m gathering as many resources as I can. Just bought a 98 Sahara with the 4.0 and AX15 5spd manual. Dana 35 rear end just blew on it. Since it needs a rebuild anyways, I’m definitely considering re gearing it. My Jeep expert says for the 31s that are on it, and the daily driving I do with it, I should get 4.10 gears. However I’m getting mixed answers from others. I’ve even used Spicer’s engine RPM calculator for different gearings.
I will be daily commuting about 15 minutes one-way on the interstate, and I want the capability to do some light off-roading (beach sand, gravel/dirt trails at Uwharrie etc). Have two kids under 2, wife and dogs and we all wanna enjoy cruising in it! Without sacrificing too much fuel efficiency, but gaining a little torque on the highways, what do you guys think I should run? Thanks in advance!
