What's included

• Box Kit for Ford Super Duty (11-14) — structural foundation for the lift assembly.
• 4.5-inch Block U-Bolt Kit with No Overloads — rear support blocks designed to eliminate common lift-block problems while maintaining stock ride quality.
• 4.5-inch Coilover Conversion Box — replaces the factory independent coil-shock setup.
• Vertex 2.5-inch Adjustable Front Coilovers (Left & Right) — nitrogen-charged, 8-stage adjustable monotube shocks with 56% greater fluid capacity than average reservoir shocks, precision-fit radius arm drop brackets for proper caster correction.

Important notes

• This kit does not fit F-350 models, gas engine models, or dually configurations.
• Trucks equipped with a 2-piece rear driveshaft require a carrier-bearing drop bracket (sold separately).
• Installation requires cutting and drilling; 6–10 hours of labor is recommended for full completion.
