A dust boot is attached to the jounce bumper and has an upper flange including a radially inwardly extending portion and an axially extending portion extending from an innermost portion of the radially inwardly extending portion. The axially extending portion has an inner diameter smaller than the outer diameter of the end portion of the jounce bumper. A rate ring secures the dust boot to the jounce bumper. The rate ring includes an inner diameter smaller than the outer diameter of the end portion of the jounce bumper.
