6 Inch Lift Kit | R/a | Ovlds | C/o Vertex | Ford F-250/f-350 Super Duty (17-22)

Built for Ford Super Duty owners who want serious clearance and a smooth ride without compromise, this 6-inch Radius Arm Coilover Conversion Suspension Lift transforms your truck's geometry while preserving factory-like handling. Run up to 37" tires, and the precision-fit radius arms keep suspension angles as close to factory specs as possible — a critical detail that protects ride quality after you lift.

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

• 6.5 In Block U-Bolt Kit (Overloads) — Fabricated steel rear blocks stronger and more durable than cast alternatives, engineered with anti-axle wrap geometry to eliminate common lift block issues while maintaining stock ride quality.
• 6" Kit Box (Coilover Conversion) — Top-mounted reservoir brackets and coil-over mounts constructed from 1/4-inch steel, designed to accept the Vertex coilovers and integrate into factory suspension points.
• Radius Arm Kit Box — Structural brackets and hardware to mount the upgraded radius arms into factory locations for an easier, more factory-like install angle.
• Radius Arm Upgrade Box (qty 2) — Ultra-durable 27 lb. each radius arms with rubber bushings for vibration absorption, precision-fit to bolt into factory mounts and preserve suspension geometry.
• Transfer Case Clocking Kit — Repositions the transfer case output to correct driveline angles after the 6-inch lift, preventing binding and ensuring smooth drivetrain geometry.
• Vertex 2.5" Adjustable Front Coilovers (Left & Right) — Monotube design with external reservoir, nitrogen-charged, 8-stage adjustable for tuning ride and handling. The 2.5-inch piston delivers 56% greater fluid capacity than typical reservoir shocks for improved damping control.
• Vertex 2.5" Rear Coilovers (qty 2) — Match-pair rear shocks with the same monotube, reservoir design for balanced suspension response across all four corners.

Important notes

• Models equipped with a 10-speed transmission require removal of the dial pin before installation.
• Does NOT fit gas engine models — diesel Super Duty only.
• Does NOT fit manual shift transfer cases.
• Does NOT fit dually models.
• Does NOT work on models equipped with the Tremor Factory Trim Package.
• Installation requires cutting and drilling; plan 6–10 hours for completion. Professional installation at Road Runner includes alignment performed in-house as part of the lift install.
