Product Details

If you're looking to give your 1980-1996 Ford F-150 a 4-inch lift, this Skyjacker SYS Box kit is a comprehensive solution. It starts with precisely engineered 1-piece strut spacers that have a specific offset to maintain proper CV axle extension within factory tolerances. This attention to detail helps prevent premature wear on your driveline components.

The kit ties the front crossmembers together with a differential skid plate, offering both rigidity and protection for your steering and driveline. You'll find everything needed for a complete installation, including front and rear brake line relocation brackets, a differential vent tube extension, and a CNC machined 6061-T6 aluminum front driveshaft spacer. For the rear, it comes with cast ductile iron blocks and longer Grade 8 U-bolts with lock nuts. All metal fabricated brackets are precisely CNC laser cut and formed, showcasing expert workmanship. The components are powder coated or zinc plated for a durable, corrosion-resistant finish.

Included are Skyjacker's Nitro Shocks, which feature a twin-tube design with 150 psi pressurized nitrogen gas for quicker response and reliable ride control. They utilize a variable 9-stage valving system for consistent oil flow and have a larger 1-3/8 inch bore piston with a leak-proof seal. The chromed piston rod offers superior corrosion resistance, and the base valve helps maintain a comfortable ride while improving tire contact with the road for better control and safety.
