A molded piston for an air spring for a vehicle suspension has an outer shell, a non-cylindrical central column braced in its relation to the outer shell by outer radial webs, and an upper surface having a recessed lower end closure seating surface. The non-cylindrical central column may have a chordal surface and a mounting stud sleeve and hole for attachment to a vehicle suspension member. The mounting stud sleeve and hole may be braced in its relation to the non-cylindrical central column by inner radial webs. The non-cylindrical central column may further have a locating sleeve and hole. The outer radial webs may be provided with Y-shaped webs connecting the outer radial webs to the outer shell and/or web arches.
