8″ 4-Link Lift Kits | 2020-2022 Ford F250/350 | NPA #460

Coldwater, MI: The latest addition to BDS Suspension's lineup for the 2017 Ford Super Duty are new 8" 4-link coilover systems allowing Ford owners to take their trucks to new heights with clearance for up to 40" tires. These new 8" 4-link coilover systems join the current 1", 2", 2.5",  4", 6" and 8" lift options offering a wide range of lift systems and accessories to outfit your late model Super Duty These new 8" coilover 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.

The standard kit uses full length ProRide coil springs to provide the lift an eliminate any potential coil bowing. The upgrade option utilizes a pair of specially tuned FOX 2.5 factory series remote reservoir coilovers to take your Super Duty to the next level. The coilovers feature a smooth bore and honed seamless alloy 2.5" body with threaded exterior for preload adjustment, 7/8" hardened steel carbon shaft, Eibach coil springs, black anodized machined 6061-T6 billet aluminum mounts and FOX's DSC (dual speed compression) adjustment technology built into the remote reservoir. DSC allows for easy adjustment of the vehicle's suspension compression dampening so you can dial in the ideal ride performance to soak up the bumps, both large and small. The DSC has 12 adjustment points for the high speed compression as well as 10 adjustment points for the low speed compression allowing you to make large or small changes to further improve your performance. Adjustments can be made by simply twisting the "blue" high speed and "gold" low speed compression knobs located on the end of the remote reservoir of the FOX 2.5 coilovers. No tools or shop adjustments needed, allowing you to tune the suspension out on the trail. These coilovers come preset right out of the box to provide 8" of lift and are valved for optimal performance with the weight of the 6.7L Powerstroke diesel engine. Installation is a breeze using the supplied frame and axle mounting brackets. Paired to these FOX coilovers are a set of auxiliary FOX 2.0 IFP performance gas shocks to mount into the factory location to further enhance damper performance 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 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 8" 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 8" 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 FOX 2.0 gas shocks to compliment the front setup for all around impressive performance.  These new 8" 4-link systems allow for clearance of 38-40" tires. Take your 2020-2022 Ford Super Duty to the next level with BDS Suspension and FOX.
