6 Inch Lift Kit | 4-link | No Ovld | M1 | Ford F-250/f-350 Super Duty (17-22)

Built for F-250 Super Duty owners who want maximum ground clearance without sacrificing driveline geometry, this 6-inch 4-Link lift kit raises your truck while maintaining proper caster angles and factory handling. The adjustable lower control arms and radius arm drop brackets let you dial in correct geometry — critical for steering feel and suspension longevity — and the kit supports 35"–37" tires, giving you serious capability on and off pavement.

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