The airspring piston of this invention in some of its aspects comprises a cylindrical center portion whose lower end defines a piston bottom including means for retaining a fastening means for attaching said piston to an unsprung portion of a vehicle, an annular dome portion extending radially outward from a top end of said cylindrical portion and ending at its outer periphery with a downwardly and outwardly arcuate bead retention portion which in turn concludes with a skirt portion which extends downwardly and flares outwardly and further downwardly to a point where the end of the skirt portion is a predetermined distance above said piston bottom. Thus, the piston, in some respect, comprises a plurality of circumferentially spaced ribs extending radially outward and axially upward from said cylindrical center portion to said bead retention portion and said dome portion and also a plurality of circumferentially spaced gussets extending radially inward from said cylindrical center portion to said fastening means retaining means.
