Built for diesel Ford Super Duty owners who want maximum lift without sacrificing ride quality, this 6-inch 4-Link Coilover Conversion Lift Kit replaces your factory independent coil setup with a beefy 2.5-inch piston Vertex Coilover system. You'll gain impressive ground clearance, proper front-to-rear level, and factory-correct caster geometry — all while running 35–37 inch tires.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

What's included

  • Box Kit | Ford Super Duty (17-22) — the structural foundation for the coilover conversion, engineered to mount and support the new suspension geometry.
  • 4.5–6in Up Arm Kit | Ford Super Duty (17-22) — durable fixed upper control arms that replace factory components and maintain proper suspension geometry.
  • 4.5–6in Lower Arms | Ford Super Duty (17-22) — adjustable lower control arms that allow fine-tuning of suspension angles and caster correction.
  • 4.5 In Block U-Bolt Kit No Overloads — rear lift blocks constructed from fabricated steel — stronger and longer-lasting than cast alternatives — designed to prevent axle wrap and maintain stock ride quality.
  • 6" Kit Box | Coilover Conversion | Ford Super Duty (17-22) — coil-over mounts and top-mounted reservoir brackets cut from 1/4-inch steel to handle the weight and movement of the new system.
  • Transfer Case Clocking Kit | Ford Super Duty (17-24) — allows proper re-indexing of the transfer case to maintain driveline angles after lift installation.
  • Vertex 2.5 Adj FR Coilovers (Left & Right, 4.5–6.0 inch) — twin monotube shocks with external reservoirs, nitrogen-charged, 8-stage adjustable damping, and 56% greater fluid capacity than average reservoir shocks for superior ride control.
  • Radius Arm Drop Brackets — maintain proper caster angle and factory handling characteristics throughout the lift range.
  • U-Bolt Hardware Kit — fasteners and backing plates for secure rear block installation.

Important notes

  • Diesel engine models only — does not fit gas Super Duty trucks.
  • 10-speed automatic transmission models must have the dial pin removed during installation.
  • Does not fit manual shift transfer cases or dually configurations.
  • Incompatible with the Tremor Factory Trim Package.
  • Installation requires cutting and drilling — plan for 6–10 hours of labor. Radius arm drop brackets and transfer case re-indexing are critical to correct caster and driveline preservation.

Why customers pick this at Road Runner

  • Professional installation by technicians who perform these 4-Link conversions weekly — no guesswork on caster correction or driveline geometry.

  • Rough Country lifetime warranty on structural and workmanship defects — backed locally and honored in person.
  • Transfer case clocking and radius arm setup done right the first time, preventing premature wear and steering issues.
  • Same-day or next-day scheduling for most installs — get lifted without losing weeks of truck time.
