Built for Super Duty owners who want 6 inches of lift without sacrificing factory ride quality, this Rough Country suspension lift kit combines increased ground clearance with precision-engineered radius arm drop brackets that preserve proper caster geometry. You'll run up to 37-inch tires while maintaining the smooth, factory-tuned handling your truck was designed for.

What's included

• 6-inch coil springs — lifted springs engineered to work with the rest of the suspension geometry for balanced front and rear ride height.
• Radius arm drop brackets — bolted to factory mounts and precision-tuned to maintain proper caster angle, protecting factory handling and drivability.
• Fabricated anti-wrap rear blocks — stronger than cast blocks, specially designed to prevent axle wrap and binding while preserving stock ride quality.
• U-bolt kits (front and rear) — heavy-duty hardware for secure suspension fastening.
• Transfer case clocking kit — compensates for suspension geometry changes to protect driveline angles.
• M1 Monotube shock pair (front and rear) — valved for balanced on-road and off-road performance.
