Everything almost! Go to rough country and read about it and check it out, there is too much to list! I got the 4" lift, 1" boomerangs, steering stabilizer,shock boots and had some bigger tires. All sold seperately but bought at the same time. Got 5.5" outta it all! And plenty off flex!Any bigger lift and SYE kit and CV driveshaft is needed.. Any other/more Q's lemme know.
