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

Built for Super Duty owners who want maximum ground clearance without sacrificing factory ride quality — this 4.5-inch coilover conversion lift kit replaces the factory independent coil setup with Rough Country's Vertex 2.5-inch adjustable coilovers, letting you run 33–35 inch tires while preserving proper suspension geometry and driveline angles.

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

• Vertex 2.5" Adjustable Front Coilovers (Left & Right) — nitrogen-charged, 8-stage adjustable shocks with monotube design and external reservoir, delivering 56% greater fluid capacity than average reservoir shocks for optimal damping control.
• Vertex 2.5" Rear Coilovers (Pair) — matched rear coilovers engineered to work in concert with the front units for balanced suspension response.
• Radius Arm Drop Brackets — precision-fit to factory mounts and designed to maintain proper caster angles, crucial for preserving factory handling and driveability.
• Fabricated Lift Blocks — stronger rear blocks with anti-axle wrap design that maintain stock ride quality while eliminating common lift-block issues.
• Transfer Case Clocking Kit — required for proper driveline geometry alignment on your model year.
• Installation Hardware & Fasteners — all bolts, brackets, and mounting hardware needed to complete the conversion.

Important notes

• 10-speed automatic transmission models must have the dial pin removed during installation.
• Does NOT fit gas engine models, dually models, or manual shift transfer cases.
• Only fits models equipped with rear factory contact overload springs.
• Does NOT work on vehicles equipped with the Tremor Factory Trim Package.
