6-Inch Lift Kit with Vertex Coilovers for Super Duty 4WD (2017–2022) with Control Arms

6-Inch Lift Kit with Vertex Coilovers, fitment-checked

Rough Country 50758 is a 6-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD models with a diesel engine. The kit pairs adjustable Vertex 2.5 front coilovers with a V2 monotube shock pair, upper and lower control arms, a front CV driveshaft, and fabricated rear blocks with U-bolts. It does not fit gas-engine, dually, manual-shift transfer case, or Tremor Factory Trim Package trucks.

This 6-inch lift kit for the 2017–2022 Ford Super Duty 4WD covers F-250 and F-350 trims from XL through Limited, including King Ranch, Lariat, Platinum, and XLT. The front converts to Vertex 2.5 adjustable coilovers rated for the 4.5–6in range, with 4.5-6in upper and lower arms and radius arm drop brackets that let you set caster back where the factory wanted it. Out back, a fabricated block replaces the factory block and works with the supplied U-bolts. Trucks with the 10-speed transmission require the dial pin to be removed. Confirm engine, transfer case, and rear axle configuration before ordering.
