A support ring used as part of an air spring assembly, where the support ring provides support for a top cap against radial forces applied by a clamping ring. The support ring is made of a plastic material which is less costly than a metal support ring. The plastic material is a high creep resistance plastic material, which provides increased strength and improved creep resistance, to withstand the compressive radial forces of the clamping ring. Once the support ring is formed, the top cap, which is also made of plastic, is overmolded such that a portion of the top cap is overmolded around the support ring. The high creep resistance plastic material is oriented during the injection molding process around the entire circumference of the support ring, to provide sufficient strength to withstand the radial forces from the clamping ring.
