Abstract: A valve assembly for a damper is provided. The valve assembly includes a housing defining a fluid cavity. The valve assembly includes a spool valve movably disposed within the housing. Further, the valve assembly includes a bumper disposed between the housing and the spool valve. At least the bumper, the spool valve and the housing together define an enclosed volume. The valve assembly further includes one or more bleed paths defined on at least one of the bumper, the spool valve and the housing, the one or more bleed paths fluidly communicating the fluid cavity with the enclosed volume.

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.
