An air spring (1700; 1800) includes a first body (1701; 1801); a first piston (1721; 1821) sealed against a first wall (1791; 1891) of the first body (1701; 1801); a cup (1702; 1802) having a second wall (1792; 1892); and a second piston (1722; 1822), wherein the cup (1702; 1802) and the second piston (1722; 1822) are configured such that: in an extended position, the second piston (1722; 1822) does not seal against the second wall (1792; 1892), in an intermediate position, the second piston (1722; 1822) seals against the second wall (1792; 1892), and as the first piston (1721; 1821) moves from the intermediate position to a compressed position, a spring rate of the air spring will increase at a higher rate than if the second piston (1722; 1822) were not sealed against the second wall.
