6 Inch Lift Kit | 4-link | Ovld | D/s | V2 | Ford F-250/f-350 Super Duty (17-22)

Built for Super Duty diesel owners who want 6 inches of lift without compromising factory geometry, this 4-Link lift kit pairs fixed upper arms with adjustable lowers to give you proper caster correction and maintained handling. You'll gain up to 37-inch tire clearance and the aggressive stance that comes with a true coil-spring lift — all while keeping the truck drivable on pavement and capable off-road.

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

• Box Kit — replaces the factory-equipped lift block with a fabricated unit engineered to prevent axle wrap while maintaining stock ride quality.
• 4.5–6in Up Arm Kit & Lower Arms — fixed upper control arms paired with adjustable lowers allow you to dial in proper caster and geometry after the lift is installed.
• Radius Arm Drop Brackets — hold the radius arms at the correct angle to preserve factory handling characteristics and keep caster angles where they belong.
• 6.5 In Block U-Bolt Kit — secures the rear springs and blocks with stainless-steel hardware.
• CV Front Drive Shaft — factory-length diesel-rated shaft accommodates the lift without binding or vibration.
• Lifted Coil Springs — engineered for 6 inches of height and balanced on-road/off-road performance.
• V2 Monotube Shock Absorbers (pair front & rear) — valved for smooth highway cruising and controlled off-road articulation, backed by Rough Country's Lifetime Replacement Warranty.
• Extended Stainless Steel Brake Lines & Brackets — ensures proper brake-system reach and safety after lift height changes.
