About this kit
6-Inch Lift Kit with V2 Shocks, fitment-checked
Rough Country 55670 is a 6-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD trucks, built around front coils, radius arm drop brackets, fabricated 4.5-inch rear blocks with U-bolts, a transfer case clocking kit, and two pairs of V2 monotube shocks. It does not fit gas-engine trucks, dually axles, manual-shift transfer cases, or trucks with the Tremor factory trim package.
This 6-inch lift kit for the 2017–2022 Ford F-250/F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, Platinum, and Limited trims listed in the fitment section. The radius arm drop brackets reset caster so steering and handling stay close to factory, while the fabricated rear blocks are shaped to limit axle wrap. Bolt-on installation raises ride height and evens out the front-to-rear stance. Confirm your engine, axle, and transfer case against the exclusion list first, then work from the downloadable Rough Country installation guide before you start.
