Abstract
An air spring for air suspension system comprises a piston assembly and a damper assembly where the piston assembly is spaced apart from the damper assembly to at least partially define an air chamber. A seal is molded with piston walls to form an integrated piston assembly. The seal includes at least one sealing lip extending radially inward from the piston assembly at an angle that is non-perpendicular to an axis of the damper and the at least one sealing lip contacts the damper assembly when the piston assembly and the damper assembly are assembled together to seal the air chamber.
