Abstract
An air suspension system for a vehicle such as a pick-up truck, wherein an air spring is mounted directly on the leaf spring of the vehicle and the air spring and leaf spring support the weight of the vehicle frame and load, effectively in series. The combination of the air spring and leaf spring provides a reduction in ride vibration whereby the vehicle rides as smoothly when it is unloaded as when it is carrying a load.
