6 Inch Lift Kit | 4-link | Ovld | D/s | Ford F-250/f-350 Super Duty (17-22)

Built for Ford Super Duty owners who want 6 inches of lift, aggressive stance, and the ability to run 35"–37" tires — this 4-Link lift kit replaces your factory control arms with Rough Country's durable fixed upper arms and adjustable lower control arms, then adds lifted coil springs, radius arm drop brackets, and specially designed anti-wrap rear blocks. You gain ground clearance and improved handling while maintaining factory geometry and proper caster alignment.

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