Abstract:
A shock absorber is disclosed having a secondary dampening assembly for dampening movement of an inner assembly within the shock absorber. The secondary dampening assembly includes a hydraulic stop piston and a hydraulic stop sleeve. The hydraulic stop piston is carried by an extender with a gap defined radially between the hydraulic stop piston and the extender to allow radial movement. The hydraulic stop sleeve has an open end for receiving the hydraulic stop piston and a flow groove that extends longitudinally along an inner surface of the hydraulic stop sleeve.
