Built for Super Duty owners who demand 35–37 inch tires without sacrificing ride quality, this 6-inch coilover conversion lift kit transforms your truck's suspension geometry while preserving factory handling. You get adjustable Vertex coilovers with 56% greater fluid capacity than standard shocks, radius arm drop brackets that maintain proper caster angles, and anti-axle wrap rear blocks that keep ride quality smooth — all in one bolt-on system.

What's included

  • 6" Lift Kit Box — foundational components for the 6-inch raise on 2017–2022 Super Duty models.
  • 4.5" Block U-Bolt Kit (No Overloads) — rear blocks engineered to prevent axle wrap while maintaining stock ride quality.
  • Coilover Conversion Kit — replaces factory independent coil shock and coil setup with the upgrade path to Vertex coilovers.
  • Vertex 2.5" Adjustable Front Coilovers (Left & Right) — monotube design with external reservoir, nitrogen-charged, 8-stage adjustable damping for up to 6-inch lift and 35–37 inch tire clearance.
  • Vertex 2.5" Rear Coilovers (Pair) — matched rear units deliver consistent damping control and suspension geometry preservation.
  • Radius Arm Drop Brackets — precision-fit to factory mounts, maintain proper caster angle for factory-like handling and driveability.
  • Transfer Case Clocking Kit — repositions the transfer case to preserve driveline geometry during the 6-inch lift.
  • Universal U-Bolt Kit — additional fastening hardware for secure installation.

Important notes

  • Does not fit gas engine models — diesel-only fitment.
  • Does not fit dually models.
  • Does not fit manual shift transfer cases — automatic transfer case required.
  • Requires rear factory contact overload springs — vehicles without OE overloads are not compatible.
  • Does not work with the Tremor Factory Trim Package.
  • Installation requires cutting and drilling; plan 6–10 hours for completion.

Why customers pick this at Road Runner

  • Geometry-corrected from day one — radius arm drop brackets and transfer case clocking preserve factory caster angles and driveline angles, so your truck handles and steers like stock despite the 6-inch raise.
  • Vertex coilovers tuned for comfort and control — 2.5-inch monotube design with 8-stage adjustability and 56% greater fluid capacity than average shocks means you dial in your own ride.
  • Rough Country's lifetime warranty backed locally — structural and workmanship defects covered for as long as you own the truck, honored right here.
  • Professionally installed by Super Duty specialists — our technicians perform these conversions weekly and know every fitment detail and torque spec.
  • Alignment included after install — we perform in-house alignment as part of every lift, so your truck drives straight and your tires wear evenly.
