6 Inch Lift Kit | Diesel | Ovld | Ford F-250/f-350 Super Duty 4wd (2017-2022)

Built for F-250 and F-350 Super Duty diesel owners who demand ground clearance and tire capacity without sacrificing drivability, this 6-inch lift kit transforms your truck's stance while preserving factory suspension geometry. Run tires up to 37 inches and gain the clearance you need — all while keeping the smooth, predictable handling that made your truck stock-ready.

What's included

• 6" Coil Box — lifted coil springs engineered to raise the front end and level the truck with the rear, delivering even ride height across the chassis.
• Radius Arm Drop Brackets — precision-fit mounts that preserve proper caster angle, crucial to maintaining factory handling and driveability on- and off-road.
• Fabricated Anti-Wrap Rear Blocks — durable, specially designed blocks that prevent axle wrap and binding while maintaining stock ride quality; stronger and longer-lasting than cast alternatives.
• N3 Shock Kit — application-valved monotube shocks tuned for balanced on- and off-road performance, delivering controlled articulation without bottoming.
• 6.5" Block U-Bolt Kit with Overloads — reinforced hardware and factory-contact overload springs that stabilize the rear axle under load.
• Transfer Case Clocking Kit — ensures proper transfer-case indexing after the lift, maintaining driveline geometry and long-term reliability.
