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

Built for diesel F-250 and F-350 Super Duty owners who want serious ground clearance and better handling without sacrificing driveline geometry, this 6-inch 4-Link lift kit replaces your factory control arms with adjustable Rough Country components and adds lifted coil springs, radius arm drop brackets for proper caster correction, and anti-wrap rear blocks. You'll gain up to 37-inch tire clearance while maintaining the balanced on-road and off-road performance Rough Country is known for.

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