About this kit
6-Inch Lift Kit with Vertex Shocks, fitment-checked
Rough Country 55650 is a 6-inch lift kit for compatible 2017-2022 Ford F-250 and F-350 Super Duty 4WD trims, built around four Vertex 2.5 shocks, a coil package, radius arm components, and a 4.5-inch rear block and U-bolt set. Read the exclusion list closely: dually, gas-engine, manual-shift transfer case, and Tremor Factory Trim Package trucks are called out as non-applications.
This 6-inch lift kit for the 2017-2022 Ford Super Duty 4WD ships as a full box set: front coils, radius arm drop and upgrade brackets, a transfer case clocking kit, a 4.5-inch fabricated rear block and U-bolt kit, and two front plus two rear Vertex 2.5 shocks. The radius arm drop hardware is what lets caster be set back into range after the lift. The factory note excludes dually trucks, gas engines, manual-shift transfer cases, 4-inch rear axle tubes, factory contact overload springs, the Tremor Factory Trim Package, and carries an F-350 caveat — confirm your configuration first, then pull the downloadable installation guide.
