I have a 77CJ with a 4" soft ride and 2 body lift and am running 33" BFG Muds. I am thinking about adding a shackle reversal kit. Will this cause problems with my Exhaust or fenders? I really do not want to trim my fenders or change my exhaust. I have heard you get better handling and articulation with these kits. I spend most of my time playing in the sand at Silver Lake Michigan but have been crawling in Colorado. And am looking at Utah this spring. What would happen if I ever tried to run 35" tires? At the truck show that run the CORR trucks they sell the tires (35" x 12.5")that have been run for $60 a piece.
