Go Big with BDS 9" System for your Ford Super Duty
Stepping up to the 9", these systems use a heavy duty front 4-link control arm conversion to upgrade the factory stamped steel radius arms for improved strength, handling, and caster control. This setup is based off BDS's tried and true 4-link setup keying off the factory radius arm frame mount and ties into the frame rail and transmission crossmember for an extremely rigid control arm mount. The brackets are build from high strength 1/4" steel, come fully welded and finished in a durable textured black powdercoat with riveted BDS nameplates. The upper and lower control arms are built from heavy wall 2" OD DOM steel tubing with massive 2-1/2" greaseable frame mount bushings and reinforced clevis mounts to attach at the axle.

This kit uses full length ProRide coil springs to provide the lift an eliminate any potential coil bowing. Pairing with the springs are your choice of BDS NX2 or FOX 2.0 IFP performance gas shocks enhance damper performance for a smooth ride on any terrain. Steering correction come in the form of a forged drop pitman arm and heavy duty track bar relocation bracket. This brings the drag link angle closer to factory and keeps the steering angles in line with the relocated track bar for improved drivability and a recentered front axle. Also supplied for the front are bump stop extensions to limit suspension compression, sway bar drop brackets to correct the sway bar positioning, replacement NX2 steering stabilizer and extended length braided stainless steel brake lines. The new front driveline design requires correction when installing the 8" lift to retain use of 4WD at any speed. To do this BDS supplies a high strength transfer case indexing ring specific to the 9" systems to rotate the front output of the transfer case down to improve the front driveline operating angle. The indexing ring uses ARP studs and includes new mounting hardware. BDS also supplies a heavy duty replacement transmission crossmember and new transfer case mounting bracket for additional clearance.

In the rear of these 9" systems BDS supplies full replacement Glideride leaf springs to provide full lift height and increased capacity with a built in overload spring. Finishing off the rear of this kit is a rear brake line relocation bracket as well as a pair of matching NX2 or FOX 2.0 gas shocks to compliment the front setup for all around impressive performance. These new 9" 4-link systems allow for clearance of up to 40" tires. Take your 2020-2022 Ford Super Duty to the next level with BDS Suspension and FOX.
