6-Inch Coilover Conversion Lift Kit for Super Duty 4WD (2017–2022)

6-Inch Coilover Conversion Lift Kit, fitment-checked

Rough Country 50757 converts the front of a 2017–2022 Ford F-250 or F-350 Super Duty 4WD to Vertex 2.5 adjustable coilovers at 6 inches of lift. Diesel engines only. Gas models, dually models, manual-shift transfer cases, and trucks with the Tremor Factory Trim Package are all outside this kit's fitment.

Coilover conversion is what sets this 6-inch lift kit for the 2017–2022 Ford Super Duty 4WD apart: left and right Vertex 2.5 adjustable front units valved across the 4.5-inch to 6-inch range replace the factory front setup, paired with Vertex 2.5 rear reservoir shocks. The box also carries matched upper and lower arm kits, a transfer case clocking kit, a universal U-bolt kit, and a fabricated 4.5-inch rear block that takes over from the factory block. Fitment covers F-250 and F-350 trims from XL to Limited. On 10-speed transmission trucks the dial pin comes out during the build.
