Suspension system of a vehicle and a shock absorber assembly of the suspension system, the shock absorber assembly includes a top mount and a jounce bumper. The jounce bumper includes a main body made of an elastic material, such as a foam elastomer or rubber and a fixing element made of a second harder material. The fixing element has a wall portion that extends around the outermost upper part of the main body and at least one elastic retaining area cooperating with a respective protuberance arranged in the top mount to fix the jounce bumper to the top mount. Between the outermost upper part of the main body and the fixing element there is a gap that enables the main body to expand radially also in the area covered by the wall portion of the fixing element when the main body is compressed during use.

A spring element, in particular a jounce bumper, for a vehicle suspension contains a longitudinal axis, a base body extending along the longitudinal axis, and an end portion positioned on a base end of the base body. The base body is elastically deformable between an uncompressed basic state and a compressed state in which the base body is at least partially compressed in the direction of the longitudinal axis. The end portion is configured for mounting the base body in a mounting cap. It is suggested that the end portion contains a plurality of at least two radially extending retention elements that are spaced apart from one another in the direction of the longitudinal axis, and each of the retention elements are configured to engage a mating retention element provided on the mounting cap.
