Gears for 35's ?
i have an 03 4.7 with the towing pkg and limited slip so the current gearing is 3.21 if im not mistaken.. i am running 35's now. What is the best gear ratio for 35's? this is my daily driver and i drive city and highway mainly, so i dont want to lose alot of MPG . i get about 8-9mpg now, how much less mpg would with gears ?
