4.5-Inch Lift Kit with Vertex Shocks for F-350 Super Duty 4WD with Transfer Case Clocking Kit

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

Rough Country 55950 is a 4.5-inch lift kit for compatible 2017–2022 Ford F-350 Super Duty 4WD trucks, built around Vertex 2.5 front and rear shocks. It does not fit gas engine models, single rear wheel models, manual shift transfer cases, trucks with the Tremor factory trim package, or 2020 models running the 10-speed transmission. Dually wheel spacers may be needed at the rear.

This 4.5-inch lift kit for the 2017–2022 Ford F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, Platinum, and Limited applications listed in the fitment section. The box holds Vertex 2.5 shocks front and rear, a front coil, fabricated rear blocks with 4.5-inch U-bolts, and a transfer case clocking kit. Radius arm drop brackets set caster back toward the factory figure, so steering feel stays predictable. Read the exclusion list closely (diesel and dual rear wheel only) then pull the downloadable Rough Country installation PDF before you start.
