6-Inch Lift Kit with M1 Shocks for 2017-2022 Ford Super Duty 4WD for Trucks without Overloads

6-Inch Lift Kit with M1 Shocks for 2017-2022 Ford Super Duty 4WD, fitment-checked

Rough Country 50440 is a 6-inch lift kit for 2017-2022 Ford Super Duty 4WD trucks, built around two pairs of M1 monotube shocks, front coils, a 4.5 in rear block and U-bolt set, and a transfer case clocking kit. It does not fit dually trucks, gas engines, manual-shift transfer cases, factory contact overload springs, a 4 in rear axle tube, or the Tremor package.

This 6-inch lift kit for the 2017-2022 Ford Super Duty 4WD ships as a kit box with a 6 inch coil box, a 4.5 in block and U-bolt kit without overloads, a transfer case clocking kit, and two M1 monotube shock pairs. Radius arm drop brackets keep caster set close to factory so steering behavior stays predictable, and the rear blocks are fabricated with anti-axle-wrap geometry. Read the exclusion list closely: the feed notes also flag F-350 models even though F-350 rows appear in the fitment table, so confirm your configuration first.
