I have a 2001 F150 4x4 regular cab long bed with a 3" PA body lift. I was curious if 18x9.5 lightning wheels with 5.8" backspacing, with some type of 35/12.5/18 all terrain or mud would rub on the torsion bars. That 5.8 backspacing worries me, I currenty have 16x10 with 4.5 backspacing with 33" and no problems. Also, anybody from central Indiana know where to get gears changed out for a reasonable price? Thanks in advance!
