Built for Super Duty owners who demand 6 inches of ground clearance without sacrificing factory ride quality — this Rough Country lift kit transforms your 2017–2022 Ford F-250/F-350 4WD while preserving the geometry that keeps your truck handling smooth on-road and off. Run tires up to 37 inches with a kit engineered around radius arm drop brackets that hold caster angles true to factory spec.

What's included

  • 6-inch coil springs — front and rear lift to 6 inches with progressive spring rates that maintain factory-like compliance.
  • Radius arm drop brackets — precision-fit to factory mounts, these brackets correct caster angles to preserve handling and driveability after the lift.
  • Fabricated anti-wrap rear blocks — stronger and longer-lasting than cast alternatives, these blocks eliminate axle wrap while keeping stock ride quality intact.
  • V2 Monotube shock absorbers (2 pairs) — purpose-valved for on and off-road balance, engineered to work with the lifted geometry.
  • Transfer case clocking kit — recalibrates the transfer case output angle to suit the raised suspension.
  • U-bolt kits — 6.5-inch overload blocks and universal 3/4 × 1 1/2-inch hardware for rear attachment.

Important notes

  • Does NOT fit gas engine models — diesel engines only.
  • Does NOT fit dually models.
  • Does NOT fit manual shift transfer cases.
  • Does NOT work on models equipped with the Tremor Factory Trim Package.
  • Tire clearance tested to 37 inches; use within the 35–37-inch range for optimal fitment and geometry.
