About this kit

6-Inch Lift Kit with M1 Shocks, fitment-checked

Rough Country 51341 is a 6-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD diesel trucks, built around two M1 monotube shock pairs, a front CV driveshaft, a 6-inch coil package, and a 4.5-inch rear block and U-bolt set. It does not fit gas engine or dually trucks, manual shift transfer cases, trucks with a 3.5-inch rear axle tube, factory contact overload springs, or the Tremor package.

This 6-inch lift kit for the 2017–2022 Ford F-250/F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, Platinum, and Limited trims listed in the fitment section. Radius arm drop brackets set caster back where the factory geometry wants it, and the fabricated rear blocks are designed to resist axle wrap. Read the exclusion list closely first — engine, axle tube, transfer case, overload spring, and Tremor qualifiers all apply. A downloadable Rough Country installation guide is available for planning the job. Shipping weight: 258.3 lb.
