6 Inch Lift Kit | Diesel | 4 Link | Ovld | Vertex | Ford F-250/f-350 Super Duty (17-22)

Built for diesel F-250 and F-350 Super Duty owners who want 6 inches of lift without sacrificing geometry or handling, this 4-Link kit replaces your factory control arms with Rough Country's durable fixed uppers and adjustable lowers. Gain the ground clearance and aggressive stance you want while maintaining proper caster through radius arm drop brackets — that means factory-like steering response and driveability, not a truck that wanders on the highway.

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