Odds are you'll rub. I ran a straight 5" CST with waay too much crank and rubbed on 35x12.50/17 rubber. Also currently running a 5" CST and 3" Body lift with a set of 285/75/18 rubber. I'm probably under cranked an inch on my TB's and I can hit my inner fender on larger drops. So yeah, you'll hit.
Hey I was told to ask you about tires and fitting sizes ... I have a 35/12.5r20 with a 4 inch suspension lift and I have a 3 inch body lift I want to put in but I'm worried the rims/tires are not gonna work not sure where to start
