A damping air spring for heavy-duty vehicle axle/suspension systems. The damping air spring includes a piston chamber and a bellows chamber and at least one opening between the chambers to provide restricted fluid communication between the chambers. A relationship between a cross-sectional area of the at least one opening in square inches to a volume of the piston chamber in cubic inches to a volume of the bellows chamber in cubic inches to a mean effective area of the air spring in square inches or of the at least one opening in square inches to a volume of the piston chamber in cubic inches to a volume of the bellows chamber in cubic inches to a unitless ratio of the volume of the bellows chamber to the volume of the piston chamber provides damping characteristics to the air spring over a first and second critical range of frequencies.
