About this kit
6-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 50740 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. Gas-engine, dually, manual-shift transfer case, 3.5-inch rear axle tube, factory contact overload spring, and Tremor package trucks are outside its fitment.
M1 monotube damping is what sets this 6-inch lift kit for the 2017-2022 Ford F-250 and F-350 Super Duty 4WD apart: two M1 shock pairs ship alongside the 4.5-6in upper and lower arm assemblies, a 6-inch coil box, a 4.5-inch fabricated block with no-overload U-bolt kit, a universal U-bolt kit, a transfer case clocking kit, and a hardware box. Radius arm drop brackets restore caster so steering feel stays close to factory. Coverage runs XL, XLT, Lariat, King Ranch, Platinum, and Limited. Verify engine, transfer case, and rear axle details first, then follow the downloadable Rough Country installation guide.
