About this kit
6-Inch Radius Arm Lift Kit, V2 Shocks — Super Duty 4WD (2017-2022), fitment-checked
Rough Country 51270 is a 6-inch lift kit built around a radius arm upgrade for 2017-2022 Ford F-250 and F-350 Super Duty 4WD diesel trucks. Two V2 monotube shock pairs, a 6-inch coil box, a 6.5-inch block and U-bolt set with overloads, and a transfer case clocking kit fill out the carton. Gas engine, dually, manual shift transfer case, and Tremor Factory Trim Package trucks are not covered.
What sets this 6-inch lift kit for the 2017-2022 Ford F-250/F-350 Super Duty 4WD apart is the pair of radius arm upgrade boxes shipped alongside the standard radius arm kit — drop brackets bring caster back into range so steering stays predictable after the lift. Rear ride height comes from a 6.5-inch fabricated block and U-bolt set with overloads, and two V2 monotube shock pairs handle damping front and rear. Confirm your truck is diesel, single rear wheel, and free of a manual shift transfer case, then follow the downloadable Rough Country installation guide.
