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

Built for F-250 Super Duty owners who want a level stance and room for bigger tires, this 4.5" lift kit raises the front to match the rear, delivering a factory-like ride with improved ground clearance and a more aggressive appearance. You'll gain the ability to fit up to 35" tires with proper wheel backspacing while maintaining correct caster geometry and driveline function.

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