About this kit
6-Inch Lift Kit with Vertex Shocks, fitment-checked
Rough Country 50850 is a 6-inch lift kit for compatible 2017–2022 Ford F-250 and F-350 Super Duty 4WD trucks, built around four Vertex 2.5 shocks — two front, two rear. It does not fit gas-engine trucks, manual-shift transfer cases, dually models, trucks with a 3.5 inch rear axle tube, or the Tremor factory trim package, and it requires factory rear contact overload springs.
This 6-inch lift kit for the 2017–2022 Ford F-250 and F-350 Super Duty 4WD covers XL through Limited trims listed in the fitment section. The box carries upper and lower radius arm components, a coil package, a 6.5 inch fabricated rear block and U-bolt hardware, a transfer case clocking kit, and four Vertex 2.5 shocks. Drop brackets let you reset caster so steering geometry stays close to factory. Confirm your engine, transfer case, axle tube, and overload spring setup against the exclusion list first, then work from the downloadable Rough Country installation guide.
