should i change gears?
hi, i have a 01 f150 supercrew 5.4L 4x4 w/ 6in suspension and 3"BL. i'm not much of a mechanic or anything but, i'm wondering what kinda gears should i get in my truck. right now i'm only running 315/75/16's with 3.55's in the back. hopefully i'll get bigger tires soon. right now i only get like 9-10 mpg and that's me baby'ing it. And i'm wondering how much will my mpg change if I get like 4.10's or 4.56's. I don't really do any highway miles, mostly to and from school, like 10 miles. Oh, and one more question, how much damage will 2.55's in the front and 3.55's in the back do to my truck, when mudding of course... I was told that as long as all the tires are spinning it would'nt hurt TOO much... Thanks alot for looking. ~ Mitch

i would go to 4.56 especially if your going to go w/ bigger tires, your torque converter will thank you. , how could you have 2.55 in the front and 3.55 in the rear. i would not run any ratio that far off in the mud or not Tcases are expensive.

No rubbing as of yet. I could have gone with 38's and trimmed a little on the front valance. I could probably make them rub if I get it arched up to much though.
