6 Inch Lift Kit | Diesel | No Ovld | Fr D/s | M1 | Ford F-250/f-350 Super Duty (23-26)

Built for Ford Super Duty diesel owners who want 6 inches of lift without sacrificing factory handling, this Rough Country suspension lift kit raises your truck while preserving the smooth, predictable geometry that makes these trucks work. Run up to 37-inch tires and keep factory ride quality — that's the difference radius arm drop brackets make.

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 box — replaces the factory coil spring perch to support the new ride height.
• 4.5-inch rear block kit with U-bolts — levels the rear axle and eliminates common lift-block problems with anti-axle wrap geometry.
• Front CV driveshaft — accommodates the new suspension angles and maintains proper driveline geometry under load.
• Radius arm drop brackets — bolt to factory mounts and preserve caster angle for factory-like steering response and tire wear.
• M1 Monotube shock pair (front) — valved N3 series shocks deliver balanced on and off-road performance.
• M1 Monotube shock pair (rear) — matched to the front for consistent damping and ride quality across all four corners.
• Installation hardware and kit box — all fasteners, brackets, and components needed for a complete bolt-on install.

Important notes

• Does NOT fit gas engine models — diesel engines only.

• Does NOT fit dually models.
• Does NOT work on models equipped with Tremor Factory Trim Package.
• Models equipped with a 10-speed transmission must remove the dial pin during installation.
