3 Inch Lift Kit | Coilover Conversion | Ford F-250 Super Duty 4wd (2005-2007)

Built for F-250 Super Duty owners who want more ground clearance and tire size without sacrificing factory ride quality — this 3-inch coilover conversion lift kit replaces your factory independent coil-shock setup with durable adjustable Vertex Coilovers and radius arm drop brackets engineered to preserve suspension geometry. You'll run 33–34 inch tires while maintaining proper caster angles and smooth highway manners.

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-inch Adjustable Coilovers (front pair) — nitrogen-charged monotube shocks with 8-stage damping adjustment, external reservoir design, and 56% greater fluid capacity than standard reservoir shocks for superior control and ride quality.
• Radius Arm Drop Brackets — fabricated to bolt into factory mounts and maintain proper caster angles, preserving factory handling and driveability.
• Track Bar Drop Bracket — corrects geometry and prevents binding as the suspension cycles.
• 2-inch Lift Blocks (rear) — fabricated steel blocks that are stronger and longer-lasting than cast alternatives.
• U-bolts — heavy-duty fasteners for secure rear block installation.
• Monotube Shock Pair — matched set tuned to work with the front coilover assembly.
• Complete Hardware Pack — all bolts, fasteners, and brackets needed for a complete installation.

Important notes

• This kit is designed for 2005–2007 F-250 Super Duty 4WD models only. Does not fit F-350, gas engine, or dually variants.
• Trucks equipped with a 2-piece rear driveshaft require an additional carrier-bearing drop bracket.
• If your truck is equipped with factory rear overload springs, u-bolt kit 7649 will be needed.
• Installation requires cutting and drilling; plan for 5–6 hours to complete the full job.
