Abstract
An end closure (260) is dimensioned for securement to a gas spring end member (204). The end closure is dimensioned to form a substantially fluid-tight, friction-fit connection with a flexible spring member (206) that is in an at least substantially-cured condition. The end closure (260) can include an end wall portion (298), a first side wall portion (300) that extends from along the end wall portion (298) and a second side wall portion (304) that is disposed radially inward of the first side wall portion and is axially-offset relative to the end wall portion. The second side wall portion at least partially forms a mounting seat that is dimensioned to form a substantially fluid-tight, friction-fit connection between at least the second side wall portion of the end closure (260) and the flexible spring member (204). A gas spring assembly as well as a suspension system and methods of assembly are also included.
