Skyjacker F8451KS-N 4 in. Suspension Lift Kit with Nitro Shocks for Ford F-250 4WD Diesel

The Skyjacker F8451KS-N is a complete 4-inch suspension lift system engineered specifically for the 2008 Ford F-250 Super Duty 4WD diesel. This is a true suspension lift — not a spacer kit — meaning your truck gains real suspension travel, improved axle articulation, and enhanced traction on uneven terrain, all while maintaining factory-like ride quality on the street.

At the core of this kit are front lift coil springs and rear lift springs, purpose-built for the heavy-duty demands of a diesel-powered Super Duty. The springs are tuned with dynamic rate balancing to deliver a smooth, controlled ride whether loaded or unloaded. This complete pallet kit is assembled and boxed at the factory with every required component included — nothing extra to source separately.

Key Features:

• 4-inch lift front and rear for increased ground clearance and the ability to run larger aggressive tires
• Nitro 8000 Series nitrogen gas-charged shock absorbers included front and rear for enhanced damping performance and stability
• Front lift coil springs specifically rated and tuned for diesel engine weight
• Rear lift springs for a level, aggressive stance
• Complete component kit with all necessary mounting hardware, brackets, and hardware for installation
• Maintains factory geometry angles, alignment specifications, and structural integrity
• Pallet kit design — all pieces boxed together at the factory to ensure nothing is missing at install time
• Limited Lifetime Warranty for the original purchaser

Skyjacker has been engineering suspension systems since 1974, and this kit reflects decades of refinement in ride quality, durability, and off-road capability. All components bolt to factory mounting locations for a straightforward installation process. Professional installation is recommended.
