I just got my first truck. It is a 2006 super crew, 4x4 F150 and I want to get a 4 inch Rough Country lift on it. I want to know if 35s will fit without rubbing or if I will have to use 33s (post pictures of your lifted trucks). Also, do any of you have a Gibson split rear exhaust on you truck. If you do, is it worth getting?
