first off you will not fit 35's without at least 6inchs of lift. 7-9 is better for offroading and rub. I don't think you would want to go over three inchs in body lift(unsafe and illegal in many states). you can go with a three inch coilover or 3inch coilspacer and a three inch body lift, pinch weld mod and trim the bottom of the bumber and run 8inch wide wheels and be okay. But your truck will be a dog with stock gearing and new gears are not cheap. red
