Six inches of lift transforms a 2017-2022 F-250 or F-350 Super Duty diesel into a capable, aggressive rig ready for larger tires and serious terrain. Rough Country's all-inclusive suspension lift kit delivers the hardware needed for a complete front-to-rear transformation, with radius arm drop brackets, lifted coil springs, fabricated rear blocks, and your choice of shock absorber upgrade, all engineered to preserve factory ride geometry and drivability.
Radius arm drop brackets keep caster in check. Proper caster angle is critical to maintaining factory handling feel after a lift. Rough Country's radius arm drop brackets bolt directly into the factory mounts, preserving the correct suspension geometry so the truck drives predictably on-road and holds up off-road without wandering or excessive tire wear.
Fabricated anti-wrap rear blocks outperform cast alternatives. The included rear blocks resist axle wrap under load and during acceleration, a common problem with lifted trucks running block-style lift. The fabricated construction offers greater strength and a longer service life than comparable cast blocks, and the anti-wrap geometry keeps the rear suspension behaving as close to stock as possible.
Multiple shock options let you tune the build to your use case. This kit is available with Rough Country's N3 series shocks for balanced on- and off-road performance, M1 monotube shocks, V2 monotube shocks, or Vertex adjustable reservoir shocks for serious off-road or performance-oriented builds. The shock absorbers are application-valved for the Super Duty's weight and suspension travel, not generic units pulled off the shelf.
Room for up to 37-inch tires. The 6-inch lift provides the clearance needed to run 37-inch tires without cutting or modifying the body, opening up a wider selection of all-terrain and mud-terrain rubber suited to the truck's intended use.
