Abstract
An air spring has a pair of spaced end members for mounting the spring at spaced locations on a structure. A flexible sleeve of elastomeric material is sealingly engaged with the end members and forms a pressurized fluid chamber therebetween. A post is mounted on one of the end members and extends into the fluid chamber. A shock absorbing bumper formed of a high strength plastic is snap-fitted on an enlarged top of the post. One or more bumper extensions are stackable and matable on top of the bumper so as to allow for height adjustment without bumper removal.
