6-Inch Vertex Coilover Lift Kit for 2017–2022 Ford Super Duty 4WD

6-Inch Vertex Coilover Lift Kit, fitment-checked

Rough Country 55659 is a 6-inch lift kit for the 2017–2022 Ford F-250 and F-350 Super Duty 4WD, built around adjustable Vertex 2.5 front coilovers and a pair of Vertex 2.5 rear shocks. Diesel drivetrains only: gas engines, manual shift transfer cases, dually axles, and the Tremor Factory Trim Package are all outside the fitment.

Two radius arm upgrade boxes set this 6-inch lift kit for the 2017–2022 Ford Super Duty 4WD apart from a plain spacer package: they ride alongside adjustable left and right Vertex 2.5 front coilovers, Vertex 2.5 rear shocks, a radius arm kit, and a transfer case clocking kit. At the rear, a fabricated 4.5-inch block and U-bolt set takes over from the factory block, with anti-axle-wrap geometry meant to hold factory ride manners. Trucks with the 10-speed transmission need the dial pin pulled during the job. Shipping weight: 326 lb.
