Designed for the 1999 and newer Ford F-350/450/550 Chassis Cab, this air suspension system features two stages of suspension, allowing for a custom-tailored ride quality to match your specific needs. The system is engineered to withstand the toughest conditions and features high-quality components, ensuring reliable and consistent performance. The industrial-strength air springs are made from heavy-duty materials and are designed to provide a long-lasting, maintenance-free ride. This design has been proven successful with over 30+ years of service on heavy-duty trucks. The air suspension framework works in conjunction with your leaf springs to maintain the same capacity but with a greatly improved ride quality. We typically see a 40-50% improvement in ride quality once this kit is installed and THAT is the main reason we have used this design since 1990. Available with or without a 2.5″ hitch receiver. The base version of this kit includes the necessary hardware, air line, fittings, and a Schrader valve for inflation. Air control systems are sold separately .
