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. A plurality of circumferentially arranged flexible fingers define an opening in a base of the bumper, and are snap-fitted over the enlarged top of the post which extends into the opening and seat inter an annular undercut formed in the post beneath the enlarged top. The snap-fitted plastic bumper replaces the heretofore used elastomeric bumper.
