About this kit
4.5-Inch Lift Kit with Vertex Shocks, fitment-checked
Rough Country 55050 is a 4.5-inch lift kit for compatible 2017-2022 Ford Super Duty 4WD trucks, built around Vertex 2.5 front and rear shocks, a coil, a fabricated block and 4.5in U-bolt package, and a transfer case clocking kit. Read the exclusion list closely: it rules out F-350, gas engine, manual shift transfer case, and dually trucks.
This 4.5-inch lift kit for the 2017-2022 Ford Super Duty 4WD ships as a bolt-on package: two Vertex 2.5 front shocks, two Vertex 2.5 rear shocks, a front coil, fabricated rear blocks with a 4.5in U-bolt kit, and a transfer case clocking kit. Radius arm drop brackets keep caster where the factory geometry wants it. Confirm your truck before ordering, since trucks with a gas engine, a manual shift transfer case, dual rear wheels, a 4" rear axle tube, the Tremor trim package, or a 2020 10-speed transmission are not covered. A downloadable installation guide is available.
