About this kit
6-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 55830 is a 6-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD models, built around coil springs, radius arm drop brackets, fabricated rear blocks, and N3 series shocks. Diesel applications only — it does not fit gas engines, dually axles, manual-shift transfer cases, a 3.5 in rear axle tube, factory contact overload springs, or the Tremor trim package.
This 6-inch lift kit for the 2017–2022 Ford Super Duty 4WD covers F-250 and F-350 trims from XL through Limited, including King Ranch, Lariat, Platinum, and XLT. The boxed kit pairs new front coils and radius arm drop brackets — which reset caster so steering feel stays close to factory — with anti-wrap fabricated rear blocks, U-bolts, a transfer case clocking kit, and application-valved N3 shocks. Work through the exclusion list first, since gas, dually, manual-shift transfer case, and Tremor trucks are outside the fitment. A downloadable Rough Country installation guide is available.
