I am getting a 3" Lift and am wanting to run 31's. will I need to regear or buy any extra parts? I am getting the RC aal 3" Lift kit. I will run 30's if the 31's will cause some problems.

IMO you dont need to regear i ran 31's on my stock 3.55's for a long time and i am still running 3.55's with 35's it just drives like a fat pig

I installed my cross breed RC/Rusty's 3" lift last weekend w 31s. You'll notice a little decrease in acceleration due to spinning more rubber. I just checked my first tank of gas.. lost 1 mpg (going from a 235/75 to the 31). I made a 1" TC drop & 2" sway bar drop brackets.

I am running 34s and stock 3.55s. Like the bumper stickers say "0-60 in 1-2 minutes!"

Did you change your drive gear in the t-case?

If not, your mileage is off b/c of the effective change in gear ratio caused by the larger tires.

I have 33s and 3.07 and I survive, I just hardly ever shift into 5th unless I am going downhill or going down a flat highway with little wind

I do want to go with some 3.73s eventually though
