A suspension system including an integrally formed axle seat provides reduced suspension system maintenance, increased reliability, reduced number of parts, reduced stress on axles, reduced manufacturing cost, and more convenient assembly as compared to conventional suspension systems. In a preferred embodiment, a suspension system has a hanger attachable to a vehicle frame, a bushing received in the hanger and fastened thereto, a spring beam pivotably attached to the bushing, an integrally formed axle seat coupling the spring beam to an axle, and an air spring mounted between the axle seat and the vehicle frame.
