a flexible bellows extending from a top end to a bottom end and enclosing an air-spring chamber between the top end and the bottom end, the top end fixable to a frame of a vehicle, the bottom end fixable to a wheel of the vehicle, a volume of the air-spring chamber varying with movement of the bottom end relative to the top end;
a first panel partially defining the air-spring chamber and movable in response to a pressure of the air-spring chamber;
an enclosure partially defining a working chamber fluidly isolated from the air-spring chamber;
a second panel partially defining the working chamber and movable relative to the enclosure, movement of the second panel changing a volume of the working chamber; and
a linkage member fixed relative to the first panel and to the second panel and defining a fixed distance between the first panel and the second panel.
