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

Built for diesel F-250/F-350 Super Duty owners who want 6 inches of lift, better geometry, and aggressive stance — this 4-Link lift kit replaces your factory control arms with Rough Country's fixed upper and adjustable lower arms, then pairs them with lifted coil springs, radius arm drop brackets, and fabricated anti-wrap rear blocks. You'll gain ground clearance, improved handling, and the ability to run 35"–37" tires while keeping factory driveline geometry intact.

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