The Drop Beam Set is the best way to lower your truck. The unique tubular design of these beams makes them the easiest and most accurate available. Beams are made from 1/4" minimum thickness heat-treated steel with a powder coated finish. Beams include performance urethane suspension bushings. Installation is simple, just remove your factory beams and replace them with the Drop Beam Set. New king pins should be installed with your Drop Beams.
