A gas spring and gas damper assembly (110; 200; 400) can include a gas spring assembly (128; 202; 402) and a gas damper assembly (130; 204; 404). The gas spring assembly can include opposing end members (206, 208; 406, 408) and a flexible spring member (210; 410) secured there between that at least partially forms a spring chamber (212; 412). One of the end members (208; 408) can include an end member chamber (268; 468) that is separated into a plurality of damping chambers (292, 294; 492, 494). Damper pistons (300, 302; 500, 502) are disposed within the damping chambers (292, 294; 492, 494) and are connected to the other end member (206; 406) by way of a damping rod (276; 476).
