Built for Super Duty diesel owners who want 6 inches of lift without sacrificing factory ride quality, this Rough Country coilover conversion kit transforms your truck's suspension geometry while letting you run 35"–37" tires safely. The precision-engineered radius arm drop brackets and 2.5-inch Vertex Coilovers preserve the factory angles that keep your truck handling and driving like it should.

What's included

  • 6" Lift Kit Box — structural core of the suspension system, engineered for Ford Super Duty 2017–2022 models.
  • Coilover Conversion Kit — replaces the factory independent coil shock setup with a modern coilover platform.
  • Vertex 2.5 Adjustable Coilovers (pair) — nitrogen-charged, 8-stage damping adjustment with 56% greater fluid capacity than average shocks; monotube design with external reservoir for superior damping control.
  • Radius Arm Drop Brackets (pair) — precision-fit to factory mounts, correcting caster geometry for proper handling and driveability.
  • CV Front Drive Shaft — diesel-specific, engineered for 4WD Super Duty models to maintain proper driveline angles.
  • 6.5" Block U-Bolt Kit — reinforces rear suspension with fabricated blocks that outlast cast alternatives.
  • Anti-Axle Wrap Rear Blocks — specialty-designed to eliminate lift block problems while maintaining stock ride quality.
  • Universal 3/4" x 1.5" U-Bolt Kit — fastening hardware sized for Ford Super Duty (2017–2022) applications.

Important notes

  • Rough Country's lifetime replacement warranty backed by local technicians who know these kits inside and out.
  • Professional alignment performed in-house as part of every lift install — critical for diesel Super Duty trucks.
