A molded piston (30) for an air spring (10) for a vehicle comprises an outer shell (32), a non-cylindrical central column (34) configured for providing lateral stiffness and strength to the outer shell (32) by being braced in its relation to said outer shell (32) by outer radial webs (46), and an upper surface (50) having a recessed lower end closure seating surface (52). The non-cylindrical central column (34) further includes a mounting stud sleeve and hole (40) braced in its relation to the non-cylindrical central column (34) by inner radial webs (44), wherein the mounting stud sleeve and hole (40) includes a spline (68) within the mounting stud sleeve and hole (40) having an inner diameter that remains constant along its length, and having an outer diameter that tapers inward along its length.
