4.5 Inch Lift Kit | C/o V2 | Ford F-250/f-350 Super Duty 4wd (2017-2022)

Built for Super Duty owners who demand serious lift without sacrificing ride quality, this 4.5-inch coilover conversion suspension lift kit replaces your factory independent coil-shock setup with adjustable Vertex 2.5-inch monotube shocks — letting you run 33–35-inch tires while maintaining factory-correct suspension geometry and handling.

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

• Kit Box — brackets, fasteners, and structural components engineered to fit your 2017–2022 Super Duty frame.
• Block U-Bolt 4.5-inch Kit — fabricated blocks (stronger and longer-lasting than cast) support the rear axle under the new ride height.
• Coilover Conversion Kit Box — conversion hardware to transition from OE coil-shock to coilover geometry.
• Transfer Case Clocking Kit — re-indexes the transfer case to maintain proper driveline angles and prevent vibration.
• Radius Arm Drop Brackets (left and right) — precision-fit to factory mounts; maintain caster correction and factory-like suspension angles for true handling and driveability.
• Vertex 2.5-inch Monotube Shock Pair — 8-stage adjustable, nitrogen-charged, with external reservoir and 56% greater fluid capacity than average; delivers optimal damping control and ride quality.
• Universal 3/4 x 4 1/2 x 12-inch U-Bolt Kit — secondary fastening for rear axle security.
