BDS 4" 4-Link Coilover Conversion Systems:  The newest addition to BDS Suspension's lineup for the 2017-2018 Ford Super Duty are 4" 4-link coilover conversion systems adding to existing 1", 2" 4", 6" and 8" lift options. These new 4" systems use a heavy duty 4-link control arm conversion to upgrade the factory stamped steel radius arms for improved strength, handling, and caster control. This new setup is based off the tried and true 4-link designed to key off the factory radius arm frame bracket (no need to remove factory bracket) 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.

In place of the factory coil springs these system upgrade to a pair of specially tuned FOX 2.5 factory series remote reservoir coilovers to take your Super Duty to the next level in performance. Available with the standard remote reservoir as well as an optional DSC (dual speed compression) adjustable reservoir, these coilovers are preset right out of the box for optimal performance with the weight of the 6.7L Powerstroke diesel engine and are an easy install using the supplied frame and axle mounting brackets. The optional DSC allows for easy adjustment for the high-speed and low-speed compression dampening by rotating the knobs to dial in the ride to your performance and ride quality needs. Paired to these FOX coilovers are a set of auxiliary FOX 2.0 IFP performance gas shocks to further enhance dampening for a smooth ride on any terrain. For steering correction a forged drop pitman arm and heavy duty track bar relocation bracket are supplied. 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 brake line relocation brackets to allow the use of the factory brake lines to speed up installation.

In the rear of these 4" systems BDS offers a replacement 5" rear block kit to replace the factory block for a level stance. Rear kits are available for both the OE 2-leaf main spring pack and OE 3-leaf main spring pack equipped trucks. The blocks are built from high strength, fully boxed steel with an integrated bump stop wing. Both the blocks and u-bolts are finished in a durable black e-coat finish. Finishing off the rear of this kit are a pair of FOX 2.0 gas shocks to compliment the front setup for all around impressive performance.  These new 4" 4-link systems allow for clearance of up to 37" tires. Take your new Super Duty to the new level with BDS Suspension and FOX.
