Will a 315/75/16 fit on a 8" rim with a 3" body lift? Has any one installed a body lift on a 97 4x4? How hard is it? I know the bolts go from top to bottom.

 

Yes, they will fit. You may have to trim a little plastic off the front bumper's lower plastic valance to fit 35's, depending on your wheels backspacing. The body lift installation is not hard, but it is time consuming. There are a lot of small, tedious steps. Get the Performance Accessories kit, it contains everything you need to complete the lift.
