Depends on tire size, if you are running 35" or taller id look into 4.88's or taller. If under 35" i think 4.10 or 4.30 if you can find them. Also depends if you tow alot. If you do i would run a short gear. A locker in the front would work better than gears if you just want to impress some snobbie LR folks! ��
I would go 3.73 or higher. I got the 3.73 and in hindsight, I should have gone with the 4.10 just because I read an article that said the gas mileage would have been within 1 mpg of each other. But I am happy with the 3.73.
