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

Built for F-250 Super Duty owners who want a leveled stance and room for bigger tires — this 4.5-inch lift kit raises your front end to match the rear, delivering a factory-like ride with an aggressive appearance. You'll clear up to 35-inch tires with proper wheel backspacing, and Rough Country's radius arm drop brackets maintain correct caster geometry so your truck handles and drives like stock.

What's included

• Lifted coil springs (front) — engineered to raise your front end while preserving ride quality and maintaining proper suspension geometry.
• M1 Monotube shocks (set of 4) — 10-stage variable nitrogen-charged shocks with 18mm spring-loaded piston rods and 54mm bodies that deliver smooth highway ride and off-road control.
• Rear blocks and U-bolts — fabricated steel blocks that are stronger and more durable than cast alternatives, securing the suspension at the correct lift height.
• Radius arm drop brackets — allow proper caster angle to be set, maintaining factory handling and driveability after the lift.
• Sway bar drop brackets and track bar — keep suspension geometry optimized for a factory-like ride even at lifted height.
• Transfer case clocking kit — repositions your transfer case for correct driveline angles and optimal performance.
