About this kit
6-Inch Vertex Coilover Lift Kit, fitment-checked
Rough Country 51759 is a 6-inch lift kit for compatible 2017-2022 Ford F-250 and F-350 Super Duty 4WD trucks, built around adjustable Vertex 2.5 front coilovers and Vertex 2.5 rear reservoir shocks. Diesel applications only: it does not fit gas engines, dually axles, manual-shift transfer cases, or the Tremor trim package, and the truck must have factory rear contact overload springs.
This 6-inch lift kit for the 2017-2022 Ford F-250 and F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, Platinum, and Limited trims. The kit box carries left and right adjustable Vertex 2.5 front coilovers, a pair of 6-inch Vertex 2.5 rear reservoir shocks, a front CV driveshaft, an overload block and U-bolt kit, and universal U-bolt hardware. Radius arm drop brackets keep caster set where the factory intended, and the fabricated rear blocks are shaped to resist axle wrap. Confirm the diesel, non-dually, non-Tremor qualifiers first, then work through the downloadable installation guide. Shipping weight: 320.3 lb.
