4.5 Inch Coilover Conversion Upgrade Kit | Vertex/v2 | Ford F-250/f-350 Super Duty (05-22)

Built for Ford Super Duty owners who want coilover-level adjustability and damping control without a full lift replacement, this 4.5" Coilover Conversion Kit swaps your factory independent coil-shock setup for a 2.5-inch nitrogen-charged Vertex Coilover with an external reservoir — delivering 56% greater fluid capacity and 8-stage adjustment. You'll gain ride height adjustability, superior damping sensitivity, and the ability to fine-tune your suspension to match your driving style and load.

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

What's included

• Vertex 2.5" Coilovers (pair) — Nitrogen-charged monotube design with external reservoir bracket, 8-stage damping adjustment, and 2.5-inch piston for increased oil capacity and damping control.
• V2 Monotube Secondary Shock (pair) — Complements the coilover system to provide optimal damping across the full stroke and improved suspension responsiveness.
• Upper & Lower Coilover Mounts (pairs) — 1/4-inch steel fabricated mounts engineered to secure the coilover assembly to your frame and control arms.
• Brake Line Relocation Brackets (pair) — Repositions factory brake lines to clear the new coilover geometry and maintain proper clearance during suspension articulation.
• Hardware & Installation Kit — All fasteners, brackets, and components needed to complete the conversion.

Important notes

• This conversion kit requires cutting and drilling during installation — it is not a bolt-on upgrade.
• Only fits models already equipped with a 4.5" Rough Country lift kit installed. This is a secondary upgrade to an existing Rough Country lift system.
• Recommended tire range is 33.0"–35.0" for optimal suspension geometry and driveline clearance.
