You'll gain up to 37" tire clearance and maintain the balanced, predictable handling that makes the Super Duty legendary.

What's included

• 6in Upper Arm Kit — Engineered to work with factory mounts for a direct bolt-on fit and proper caster geometry.
• 6in Lower Control Arms — Adjustable at the axle to dial in caster after install, ensuring factory-like handling and tire wear.
• 6 Inch Coil Box — Lifted coil springs that support the new ride height while balancing on and off-road performance.
• 3 Inch Block & U-Bolt Kit — Rear lift block and hardware for leveling the truck bed with the front.
• Add-A-Leaf — Supplemental leaf to maintain rear spring rate and payload capacity.
• M1 Monotube Shock Pair (Front & Rear) — Rough Country's N3 series shocks deliver balanced ride quality for daily driving and light off-road use, with integrated valving tuned to this kit's geometry.
• Track Bar Relocation Bracket & Drop Pitman Arm — Repositions steering and tracking components to maintain factory angles and prevent bump steer.
• Brake Line Relocation Brackets — Keeps brake lines clear of suspension movement and new driveshaft angles.

Important notes

• Does NOT fit diesel engine models, dually models, or vehicles equipped with rear overload springs.
• Requires exhaust modification to clear the front driveshaft — coordinate this before or as part of your install appointment.
• Caster adjustment at the lower control arms is necessary and included as part of professional installation to ensure proper geometry and tire wear.

Why customers pick this at Road Runner

• Radius arm drop brackets hold factory-correct caster angles — the difference between a truck that drives like stock and one that pulls to the side.
• Adjustable lower control arms let our techs dial in caster on the hoist, so you leave with perfect geometry and predictable handling.
• Backed by Rough Country's Lifetime Replacement Warranty and installed by technicians who do this lift every week.
• Alignment performed in-house as part of every lift install — no separate trip to a chain shop.
• 100% bolt-on design — no cutting, drilling, or fabrication needed, so most trucks roll out the same day.
