6 Inch Lift Kit | Diesel | 4-link | No Ovld | V2 | Ford F-250/f-350 Super Duty (17-22)

Built for diesel Super Duty owners who want a 6-inch lift without sacrificing factory drivability — this 4-Link lift kit replaces your factory control arms with Rough Country's fixed upper arms and adjustable lowers, plus radius arm drop brackets that preserve proper caster geometry. You'll gain up to 37-inch tire clearance and improved suspension travel while the specially designed anti-wrap rear blocks keep your ride planted and smooth.

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