About this kit
6-Inch Lift Kit with Vertex Shocks, fitment-checked
Rough Country 51350 is a 6-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD diesel models, built around four Vertex 2.5 shocks, a coil package, fabricated anti-axle-wrap rear blocks, and a transfer case clocking kit. It does not fit gas engine, dually, manual-shift transfer case, or Tremor Factory Trim Package trucks.
This 6-inch lift kit for the 2017–2022 Ford F-250 and F-350 Super Duty 4WD covers XL through Limited trims, including King Ranch, Lariat, Platinum, and XLT. Radius arm drop brackets keep caster where it belongs, so factory steering feel and driveability carry over. Fabricated rear blocks are paired with a U-bolt kit and designed to resist axle wrap, while front and rear Vertex 2.5 shocks handle damping on pavement and off it. Confirm your truck against the exclusion list first, then work from the downloadable Rough Country installation guide, which also covers the clocking ring.
