6-Inch Lift Kit with Vertex Coilovers for Super Duty 4WD (2017–2022), Part 50456

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

Rough Country 50456 is a 6-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD models, built around Vertex 2.5 adjustable front coilovers and a V2 monotube rear shock pair. It does not fit gas engine trucks, dually trucks, manual shift transfer cases, or trucks with the Tremor factory trim package, and the truck must have factory rear contact overload springs.

This 6-inch lift kit for the 2017–2022 Ford F-250 and F-350 Super Duty 4WD covers XL through Limited trims listed in the fitment section. The kit pairs left and right Vertex 2.5 adjustable front coilovers with a V2 monotube rear shock pair, adds a transfer case clocking kit, and uses a 4.5 inch fabricated rear block and U-bolt package designed to resist axle wrap. Radius arm drop brackets keep caster where it belongs so steering feel stays close to factory. Confirm engine, axle, transfer case, and overload spring details before ordering.
