6 Inch Lift Kit | Gas | Ovld | C/o Vertex | Ford F-250 Super Duty (11-14)

Built for Ford F-250 Super Duty owners who want commanding ground clearance and factory-smooth handling, this 6-inch coilover conversion lift kit replaces the factory independent coil setup with precision-tuned Vertex coilovers. Run up to 37-inch tires while preserving driveline geometry — radius arm drop brackets maintain proper caster angles so your truck rides and handles like it should, not like a lifted truck.

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

Important notes

• This kit does not fit F-350 or dually models.
• Confirm whether your truck's rear leaf springs are equipped with a factory contact overload spring — kit compatibility depends on this.
• Gas models may require exhaust modification to clear the front driveshaft during installation.
• Installation requires cutting and drilling; plan 6–10 hours for full completion.
