About this kit
6-Inch Lift Kit with Vertex Coilovers, fitment-checked
Rough Country 51357 is a 6-inch lift kit for the 2017-2022 Ford F-250 and F-350 Super Duty 4WD, built around a Vertex 2.5 coilover conversion up front and Vertex 2.5 rear shocks. It does not fit gas engine models, dually axles, 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 Super Duty 4WD covers F-250 and F-350 trims from XL through Limited in the fitment list. The box pairs adjustable Vertex 2.5 front coilovers, left and right, with two Vertex 2.5 rear shocks, a 4.5-inch fabricated rear block and U-bolt set, a universal U-bolt kit, and a transfer case clocking kit. Radius arm drop brackets set caster back where the factory geometry wants it, and the rear blocks are shaped to resist axle wrap. Confirm the engine, axle, and transfer case qualifiers first, then work from the downloadable installation guide.
