About this kit

6-Inch Lift Kit with V2 Shocks, fitment-checked

Rough Country 55870 is a 6-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD models, built around radius arm drop brackets, a coil package, fabricated rear blocks, and two pairs of V2 monotube shocks. It does not fit gas engine trucks, dually axles, manual-shift transfer cases, or trucks with the Tremor factory trim package.

This 6-inch lift kit for the 2017–2022 Ford Super Duty 4WD covers F-250 and F-350 trims from XL through Limited, including King Ranch and Platinum. Radius arm drop brackets set caster back where the factory geometry wants it, while fabricated rear blocks with anti-axle-wrap design handle the back of the truck. Check the exclusions first: gas engines, dually axles, manual-shift transfer cases, and Tremor-equipped trucks are all out. Installation is bolt-on, and a downloadable Rough Country installation guide is available to walk the sequence before you start.
