For the 3.8 with auto and 35s the 5.13s are by far the most popular, 4.88s are the go to gears for 6spds. Youíll always find a few people that will break the mold; Iím just telling you what the vast majority use.

If you plan on doing a moderate amount of towing then perhaps 5.38s might be worth looking into. Do plenty of research as it isnít a cheap endeavor.
