Have searched and gave not come up with an answer that is specific enough. I am running a 2009 2dr X that I have a 2.5 inch lift, pro comp alloy wheels 17 x 9 with Mickey Thompson Baja claws that are 33 2.50 R17. I have stock Dana 30 front and stock Dana 44 in the rear. It's a DD that sees the highway twice a week 60 mile drive. I get 14.8 mpg on the highway. My question is would going to 4:53 or 4:1 help with my mpg? I have looked at chart and thought going 4:88 or would that be over kill?

 

Forgot to also include that its a 6 speed.

 

2dr, 6spd, 33s. I would go with 4.56 for that setup. Now you need to think if you will EVER go bigger than 33s. If you might go bigger consider more gear. Although, as long as you don't go bigger than 35s, the 4.56s will work.

 

I don't think I will get any larger than 35's since mostly a DD.
