About this kit
6-Inch Lift Kit with Vertex Coilovers, fitment-checked
Rough Country 50459 is a 6-inch lift kit for supported 2017-2022 Ford F-250 and F-350 Super Duty 4WD trucks, built around a Vertex 2.5 adjustable coilover conversion up front and Vertex 2.5 reservoir shocks at the rear. Diesel models only. It does not fit gas engines, dually axles, manual shift transfer cases, or the Tremor factory trim package, and the truck must have rear factory contact overload springs.
This 6-inch lift kit for the 2017-2022 Ford F-250 and F-350 Super Duty 4WD converts the front end to Vertex 2.5 adjustable coilovers and matches them with a pair of Vertex 2.5 reservoir rear shocks. Radius arm drop brackets bring caster back toward the factory setting so steering feel stays familiar, while fabricated rear blocks and a 4.5-inch block U-bolt kit handle axle wrap. A front CV driveshaft is part of the package. Confirm your truck is diesel, single-rear-wheel, and equipped with factory contact overload springs before ordering. A downloadable installation guide is available.
