Abstract

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