4.5-Inch Vertex Coilover Lift Kit for Ford Super Duty 4WD (2017–2022)

4.5-Inch Vertex Coilover Lift Kit, fitment-checked

Rough Country 55056 is a 4.5-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD models, built around adjustable Vertex 2.5 front coilovers and a V2 monotube rear shock pair. It only suits diesel trucks with factory rear contact overload springs. Gas, dually, manual-shift transfer case, and Tremor Factory Trim Package trucks are outside the fitment.

This 4.5-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. Left and right Vertex 2.5 adjustable front coilovers handle the front lift, a V2 monotube pair goes in back, and fabricated anti-axle-wrap rear blocks ship with matching U-bolts to keep the factory ride manner intact. Radius arm drop brackets reset caster so steering feel stays close to stock, and a transfer case clocking kit is part of the package. Trucks with the 10-speed transmission need the dial pin removed. Confirm the exclusion list before ordering.
