6-Inch Lift Kit with Vertex Shocks for Super Duty 4WD (2017–2022) with Front CV Drive Shaft

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

Rough Country 56051 is a 6-inch lift kit for compatible 2017–2022 Ford Super Duty 4WD trucks, built around Vertex 2.5 front and rear shocks, upper and lower arm kits, a coil box, a 6.5-inch block and U-bolt package, and a front CV driveshaft for diesel applications. Read the fitment qualifiers first: gas engines, dually trucks, manual shift transfer cases, 4-inch rear axle tubes, and Tremor Factory Trim Package trucks are all outside this kit's coverage.

This 6-inch lift kit for the 2017–2022 Ford Super Duty 4WD covers XL through Limited trims listed in the fitment section, and the BOM pairs 4.5–6in upper and lower arm kits with two Vertex 2.5 front and two Vertex 2.5 rear shocks. Radius arm drop brackets set caster back where it belongs, and a fabricated rear block replaces the factory lift block. The kit only suits trucks with factory rear contact overload springs, and F-350, gas-engine, dually, manual-shift-transfer-case, and Tremor Factory Trim Package trucks are excluded. A downloadable Rough Country installation guide is available.
