Going to be putting on 35s I have a 2010 sport with Dana 44 in the rear and Dana 30 in the front, I want to keep close to the stock mpg 18 to 19 on highway. Os what gears do I need and what else do I need to do to what I have ATM. I will upgrading the axles at a later date. Thanks all

 

I see you have a 6-speed.

You say you are going with 35s and are concerned with MPG.

Find some 4.56s if you can, but they are near impossible to find. If not, do not go lower than 4.88.
