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

Built for F-250 Super Duty owners who want a level stance with room for bigger tires, this 4.5-inch lift kit raises the front to match the rear, delivering the aggressive look and improved ground clearance diesel owners demand. You'll gain up to 35-inch tire capability while maintaining factory-correct caster geometry for predictable handling on and off the road.

What's included

• Lifted coil springs — Front springs engineered to raise the front end while preserving ride quality and load capacity.
• Block and U-bolt assembly — Fabricated steel blocks stronger and longer-lasting than cast alternatives, paired with properly sized U-bolts for secure axle mounting.
• CV driveshaft — Front driveshaft engineered for diesel F-250/F-350 4WD models to maintain proper angles and durability after the lift.

• Sway bar drop brackets and track bar — Keep suspension geometry optimized for balanced on-road and off-road performance.
