3 Inch Lift Kit | Diesel Coilover Conversion | Ford F-250 Super Duty (23-26)

Built for F-250 Super Duty owners who want a commanding 3-inch lift without sacrificing factory ride quality, this coilover conversion kit replaces the factory independent coil-shock setup with premium Vertex 2.5-inch nitrogen-charged coilovers. The radius arm drop brackets preserve critical caster geometry, keeping your truck's handling and driveability as close to factory as possible — and you can run 33"–34" tires safely.

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 monotube shocks with external reservoir for 56% greater fluid capacity than average reservoir shocks, delivering superior damping control and ride quality.
• V2 Monotube Shock Pair — Premium damping units engineered for consistent performance across a wide range of terrain and load conditions.
• Radius Arm Drop Brackets — Precision-fit to factory mounts for proper caster angle preservation and easier installation while maintaining factory-like suspension geometry.

• Installation Hardware & Fasteners — All components needed for a complete bolt-on installation.

Important notes

• This kit is designed for F-250 Super Duty 4WD models only. Does NOT fit F-350 models, dually models, or diesel engine models.
• Trucks equipped with a 2-piece rear driveshaft require a carrier-bearing drop bracket (sold separately).
• Installation requires cutting and drilling; plan for 6–10 hours of labor.
