I have an 04 with a 6in lift. I am thinking about going from 37's to 35's. What gearing would work best? I am trying to improve my MPG. Other than gearing what else can I do to improve the MPG?

 

What kind of driving do you do most and what gearing do you have now? If city driving the 4.56 and 35s combo seems to work out for most. If you do a lot of highway driving, 4.10s may be better with the 35s. If you have 3.73s and do mostly highway driving, a switch to 4.10s probably won't make a big enough difference to justify cost.

 

honestly the large tires will get bad mileage no matter what. Just drive it very nice and get some MPG mods
