Abstract
A damper assembly for a vehicle suspension system includes a primary damper and a secondary damper. The secondary damper includes a housing having a wall that at least partially surrounds at least a portion of the primary damper, the volume between the wall and the primary damper defining a chamber, and the wall defines an aperture. The secondary damper also includes a piston positioned within the chamber, a conduit defining a flow path that includes the aperture, and a valve disposed along the flow path. The primary damper is configured to provide a base damping force and the secondary damper is configured to provide a supplemental damping force that varies based on the position of the piston within the chamber.
