About this kit
6-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 50340 is a 6-inch lift kit for compatible 2017-2022 Ford Super Duty 4WD trucks, built around two M1 monotube shock pairs, a 6-inch coil package, a 6.5 in block and U-bolt set, and a transfer case clocking kit. Read the exclusion list first: it rules out dually trucks, gas engines, manual-shift transfer cases, and the Tremor factory trim package.
This 6-inch lift kit for the 2017-2022 Ford Super Duty 4WD covers XL, XLT, Lariat, King Ranch, Platinum, and Limited trims shown in the fitment section. Radius arm drop brackets set caster back where the factory geometry wants it, and the fabricated rear blocks are shaped to limit axle wrap. Rough Country lists this as a bolt-on install, and the exclusions are strict: no F-350, dually, gas-engine, or manual-shift transfer case trucks, nothing with a 4-inch rear axle tube, and rear factory contact overload springs must already be present. A downloadable installation guide is available.
