About this kit
6-Inch Lift Kit with Vertex Coilovers for Super Duty 4WD (2017–2022), fitment-checked
Rough Country 50356 is a 6-inch lift kit for 2017–2022 Ford F-250/F-350 Super Duty 4WD models, built around a coilover conversion using Vertex 2.5 adjustable front units and a V2 monotube shock pair out back. It only suits trucks with rear factory contact overload springs, and it rules out gas engines, dually axles, manual-shift transfer cases, and the Tremor factory trim package.
This 6-inch lift kit for the 2017–2022 Ford F-250 and F-350 Super Duty 4WD covers XL through Limited trims, including King Ranch, Lariat, Platinum, and XLT. The box carries left and right Vertex 2.5 adjustable front coilovers, a V2 monotube shock pair, a transfer case clocking kit, and a 6.5-inch rear block and U-bolt package. Radius arm drop brackets keep caster where the factory intended, so steering feel stays predictable, and the fabricated rear blocks are shaped to resist axle wrap. Confirm your engine, axle, and transfer case type against the exclusion list first. Shipping weight: 258.3 lb.
