6-Inch Lift Kit with N3 Shocks for 2017–2022 Ford Super Duty 4WD, Part 55830

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.
