6-Inch Lift Kit with Vertex Shocks for Ford Super Duty 4WD, Part 51750

6-Inch Lift Kit with Vertex Shocks, fitment-checked

Rough Country 51750 is a 6-inch lift kit for 2017-2022 Ford F-250 and F-350 Super Duty 4WD models, built around four Vertex 2.5 shocks, a coil package, fabricated rear blocks with U-bolts, and a transfer case clocking kit. Diesel-only fitment: it does not fit gas engine, dually, manual-shift transfer case, or Tremor Factory Trim Package trucks, and the truck must have factory rear contact overload springs.

This 6-inch lift kit for the 2017-2022 Ford F-250 and F-350 Super Duty 4WD covers XL through Limited trims listed in the fitment section. The box pairs Vertex 2.5 front and rear shocks with a coil package, a 6.5-inch block and U-bolt set, and a transfer case clocking kit, with radius arm drop brackets to keep caster where the factory geometry wants it. Confirm your truck before ordering: rear factory contact overload springs are required, and trucks with a 3.5-inch rear axle tube are excluded. A downloadable installation guide is available.
