4.5 Inch Lift Kit | Fr D/s | M1 | Ford F-250/f-350 Super Duty 4wd (2017-2022)

Built for Ford Super Duty owners who want a leveled stance and room for 35-inch tires, this 4.5-inch lift kit raises the front to match the rear for a factory-balanced appearance while preserving proper caster geometry and driveline angles. You get lifted coil springs, radius arm drop brackets, a front CV driveshaft, and a pair of premium M1 monotube shocks tuned for both highway comfort and off-road capability.

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

What's included

• Lifted front coil springs — engineered for the 4.5-inch height gain while maintaining ride quality and load-carrying capacity.
• Radius arm drop brackets — preserve factory caster angles for proper steering feel and tire wear after the lift.
• Front CV driveshaft — accommodates the new suspension geometry and prevents binding at full articulation.
• Sway bar drop brackets and track bar — keep suspension geometry optimized and maintain factory-like handling.
• Rear fabricated lift blocks — stronger than cast alternatives and designed to outlast the vehicle.
• Pair of M1 monotube shocks — 10-stage variable high-pressure nitrogen-charged units with 18mm spring-loaded piston rods and 54mm shock bodies for highway smoothness and off-road performance.
• U-bolt kits — everything needed to secure the blocks and coils properly.

Important notes

• Does NOT fit gas engine models — diesel-only.
• Does NOT fit manual shift transfer cases.
• Does NOT fit dually models.
• Does NOT fit models with 3.5-inch rear axle tubes.
• Does NOT work with the Tremor Factory Trim Package.
