About this kit
6-Inch Lift Kit with Vertex Coilovers, fitment-checked
Rough Country 50458 is a 6-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD diesel models, built around adjustable Vertex 2.5 front coilovers and a V2 monotube rear shock pair. It does not fit gas-engine trucks, dually axles, manual-shift transfer cases, or trucks with the Tremor Factory Trim Package, and the truck must have rear factory contact overload springs.
This 6-inch lift kit for the 2017–2022 Ford F-250/F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, Platinum, and Limited trims listed in the fitment section. The coilover conversion uses left and right Vertex 2.5 adjustable front units rated across the 4.5-inch to 6-inch range, with a V2 monotube shock pair and a 4.5-inch fabricated rear block and U-bolt kit out back. Radius arm drop brackets set caster back where the factory geometry wants it. Confirm engine, axle, transfer case, and overload-spring configuration before ordering, then work through the downloadable Rough Country installation guide.
