About this kit
6-Inch Vertex Lift Kit, fitment-checked
Rough Country 50756 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. Diesel applications only — it does not fit gas engines, manual-shift transfer cases, dually models, or the Tremor factory trim package.
This 6-inch lift kit for the 2017–2022 Ford Super Duty 4WD covers F-250 and F-350 trims from XL through Limited. The box carries Vertex 2.5 adjustable front coilovers rated for the 4.5-6in range, a V2 monotube shock pair, upper and lower control arms, a transfer case clocking kit, fabricated rear blocks with U-bolts, and radius arm drop brackets that let caster be set correctly. Trucks with the 10-speed transmission need the dial pin removed. Check the exclusion list against your build, then work from the downloadable Rough Country installation guide.
