Abstract: A suspension system includes a shock absorber body, a piston rod that projects upwardly from the upper end of the shock absorber body, and a mount that is provided on the projecting end portion of the piston rod to attach the projecting end portion to a vehicle body. The mount includes a first mounting member that is attached to the piston rod, a second mounting member that is attached to the vehicle body, and a rubber mount member that is provided between the first and second mounting members. The rubber mount member has a pair of thick- and thin-walled diametrically opposing portions. The suspension system further includes engagement members to which a retainer is disengageably attached to retain the thick-walled portion of the rubber mount member in a compressed state.
