Built for Ford Super Duty owners who demand maximum ground clearance without sacrificing ride quality, this 6-inch coilover conversion lift kit transforms your truck's stance while preserving factory-like handling geometry. You'll clear up to 37-inch tires and gain the adjustable damping control of Rough Country's 2.5-inch Vertex coilovers — engineered to maintain proper suspension angles through radius arm drop brackets that bolt to factory mounts.

What's included

  • 6" Kit Box — Main structural components for your 6-inch lift height.
  • Vertex 2.5 Adjustable Front Coilovers (Left & Right, 4.5"–6") — Nitrogen-charged, 8-stage adjustable shocks with monotube design and external reservoir for superior damping control and oil capacity.
  • Vertex 2.5 Rear Coilovers (qty 2, 6") — Matched rear units engineered for level ride and anti-axle wrap performance.
  • Coilover Conversion Kit Box — Everything needed to swap from factory independent coil-shock setup to the Vertex system.
  • CV Front Driveshaft (Diesel, 4WD) — Replaces factory shaft to maintain proper angles and eliminate binding at full lift height.
  • Radius Arm Drop Brackets — Preserve correct caster geometry for factory-like handling and steering response.
  • 6.5" Block U-Bolt Kit — Rear suspension fasteners for secure mounting.
  • Universal 3/4 x 4 1/2 x 12" U-Bolt Kit — Additional fastening hardware for complete assembly.
