6 Inch Lift Kit | Diesel | No Ovld | C/o Vertex | Ford F-250 Super Duty (15-16)

Built for diesel F-250 Super Duty owners who want maximum ground clearance without sacrificing factory ride quality, this 6-inch coilover conversion lift kit replaces your factory independent coil-shock setup with adjustable Vertex coilovers that preserve suspension geometry and let you run 35–37 inch tires while maintaining proper caster angles for predictable handling and driveability.

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