4.5 Inch Lift Kit | Fr D/s | Ford F-250/f-350 Super Duty 4wd (2017-2022)

Built for Super Duty owners who want a leveled stance with room for bigger rubber, this 4.5-inch lift kit raises the front of your truck to match the rear for a factory-proportioned look. Rough Country's coil-spring design, caster-corrected radius arms, and N3 shocks preserve ride quality while clearing up to 35-inch tires with proper wheel backspacing.

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