I have a 2006 LE Off Road 4X4. I am running 275/60/20's Cooper Discoverers. I am about to throw on the Cooper Zeons same size. I want to level out the truck or maybe do a mini lift. Keep in mind I may want to go bigger on tires in the future. I tow a car hauler loaded with a mower and landscape equipment in the summer. I have read through some of the other posts and can't decide what to do. I only want to do this once and be happy with it. What is the difference between a 2.5" leveling kit and a 3" mini lift? Do I need anything in the rear? Any help will be greatly appreciated.
