Help needed please. I am going to regear my 2013 JKU, it currently has 3.21 and was thinking 4.10 or 4.56. Running 35" BFG Mud, and an auto tranny. I do use the jeep as a daily driver, 60 miles round trip, so looking for the best and possibly a mpg increase. Like to hear your thoughts. New to the Jeep world, and want to enjoy the ride more than we already do.

scroll down to the section on Axels, Gears and Drivetrains. Good information as well as charts that will show you gear ratios for your engine/trans/tire size
