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

Built for Super Duty diesel owners who want aggressive ground clearance and factory-corrected geometry — this 6-inch lift kit combines a 4-Link control arm setup with fabricated rear blocks and radius arm drop brackets to deliver the height you want without sacrificing driveline angles or handling. Run 35"–37" tires confidently with properly maintained caster and a suspension tuned for both highway comfort and off-road performance.

What's included

• N3 Shock Kit — nitrogen-charged shock absorbers engineered for Super Duty geometry, balancing off-road compliance with highway composure.
• 6.5" Block U-Bolt Kit with overloads — fabricated rear lift blocks stronger and longer-lasting than cast alternatives, designed to eliminate axle wrap while maintaining stock ride quality.
• Coil Box — lifted coil springs that raise the front end in line with the rear for level stance and balanced suspension travel.
• Upper and Lower Control Arms (4-Link upgrade) — fixed upper arms and adjustable lower control arms replace factory geometry with a tuned 4-Link setup for improved articulation and control.
• Radius Arm Drop Brackets — hold proper caster angles to preserve factory handling and driveability after the lift is installed.
• CV Front Drive Shaft — constant-velocity driveshaft engineered for diesel models to maintain smooth power delivery at lifted angles.
• Extended Brake Lines & Brackets — stainless steel lines and mounting hardware route brake hoses safely through the new suspension geometry.
• U-Bolt Kit — secures the lift components and manages suspension articulation.
