About this kit
6-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 50420 is a 6-inch lift kit for the 2017–2022 Ford Super Duty 4WD, built around a coil package, fabricated anti-axle-wrap rear blocks with a 4.5-inch block U-bolt kit, a transfer case clocking kit, and application-valved N3 series shocks. Read the exclusions first: it does not fit F-350, dually, gas-engine, manual-shift transfer case, or Tremor Factory Trim Package trucks, models with a 4-inch rear axle tube, or trucks with rear factory contact overload springs.
This 6-inch lift kit for the 2017–2022 Ford Super Duty 4WD covers XL through Limited trims, including King Ranch, Lariat, Platinum, and XLT. Radius arm drop brackets let you set caster back where it belongs so steering feel stays close to factory, and the fabricated rear blocks are shaped to resist axle wrap rather than trade away ride quality. Installation is bolt-on, and a downloadable Rough Country installation guide is available covering both the kit and the clocking ring. Work through the full exclusion list against your build sheet before ordering. Shipping weight: 228.3 lb.
