The heart of this system is the 4-link conversion that replaces the factory radius arm. Benefits include increased stability, wheel travel, and improved handling across all terrains. Included are a pair of massive frame-mounted brackets precision welded and engineered to locate the new upper and lower control arms to create the optimal suspension geometry. Removal of the factory radius arm brackets is not required and allows the brackets to stay intact to speed up the installation time and make these kits reversible. The additional front height comes from a pair of specially designed progressive rate ProRide coil springs. The 4in coils have been engineered and tested to improve the ride quality and performance across all terrains while holding up to the rigors that 3/4-ton truck owners demand. A heavy duty track bar relocation bracket is included to recenter the front axle once lifted as well as a forged drop pitman arm to correct steering angles. Sway bar relocation brackets are used to reposition the front sway bar assembly and the supplied brake line brackets allow for the easy adjustment for the stock lines to be reused with the lift kit. In the rear, 1/4in steel, 3.5in tall gusseted air bag spacers are used along with a rear track bar bracket to correct axle positioning, extended length sway bar links, and bump stop extensions. BDS supplies new air ride leveling sensor brackets to position the ride height sensors at the stock angle. This allows the rear suspension to perform just like it does at factory ride height and maintain full air bag range of motion.
