Ok I have been doing some research and the different gears and I am wondering if it would be a good idea to do this. My truck has the 3.36 gears I am wanting to drop it down to the 2.94 gears I do not tow and thing much and the 3.36 gears is killing me with gas millage. I have always wondered why some people get 15-17 mpg and some 9-12. I am currently getting 9mpg. Why are the advantages and disadvantages of swapping the gears like this? I know it would improve gas millage but would it hurt me in performance?
