Abstract
In a shock absorber for a vehicle, a piston rod extends through a piston rod guide into a cylinder and its end within the cylinder is attached to a damping piston. A stop assembly is mounted on the piston rod close to the damping piston and spaced from the piston rod guide. The stop assembly includes an axially extending sleeve laterally enclosing the piston rod. The end of the sleeve can be secured directly to the piston rod or a support device can be secured to the piston rod and disposed in contact with the end of the sleeve. When the piston rod is displaced relative to and out of the cylinder, the stop assembly contacts the piston rod guide. The piston rod can be a solid rod member or a tubular member with solid end connections.
