6 Inch Lift Kit | Diesel | 4 Link | Ovlds | C/o Vertex | Ford F-250/f-350 Super Duty (05-07)

Built for diesel Super Duty owners who demand ride quality and geometry-correct lift without compromise, this 6-inch 4-Link Coilover Conversion Lift Kit replaces your factory independent coil setup with adjustable Vertex coilovers and a properly-engineered control-arm geometry. You'll clear 35–37 inch tires while maintaining factory handling through radius arm drop brackets that preserve correct caster — the difference between a truck that drives like stock and one that wanders.

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