6 Inch Lift Kit | Diesel | No Ovld | M1 | Ford F-250/f-350 Super Duty (17-22)

Built for F-250 Super Duty diesel owners who want maximum ground clearance without sacrificing ride quality, this 6-inch radius arm lift kit raises your truck while preserving factory suspension geometry. You'll clear up to 37-inch tires and maintain smooth, predictable handling — the result of precision-engineered drop brackets that keep caster angles factory-close.

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

• 6-inch coil springs — engineered to handle the weight of your diesel while maintaining ride compliance.
• Radius arm drop brackets — precision-fit to factory mounts for easier installation and proper caster geometry.
• Fabricated anti-wrap rear blocks — stronger and longer-lasting than cast alternatives; designed to prevent axle wrap and binding.
• Transfer case clocking kit — re-indexes the transfer case to maintain proper driveline angles after the lift.
• M1 Monotube shock pair (front and rear) — N3-series valved absorbers tuned for balanced on- and off-road performance.
• 4.5-inch block U-bolt kit — secures the rear blocks and suspension components.

Important notes

• Not compatible with models equipped with rear factory contact overload springs.
