Abstract
An air suspension system for a load bearing vehicle which includes a pair of air springs fluidly connected to a pair of auxiliary air reservoirs and to a main air reservoir. The system includes control valves which permit the air in the air springs to be exhausted therefrom to lower the vehicle frame without exhausting the air from the auxiliary air reservoirs.
