6 Inch Lift Kit | 4 Link | Ovld | Vertex | Ford F-250 Super Duty 4wd (15-16)

Built for F-250 Super Duty owners who want serious ground clearance and improved handling without sacrificing factory ride quality, this 6-inch 4-Link lift kit replaces your factory rear arms with Rough Country's durable, adjustable setup while adding up to 37-inch tire clearance. Radius arm drop brackets preserve caster geometry—critical to maintaining factory handling and driveability—while anti-wrap rear blocks eliminate common lift-kit binding issues.

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