A shock absorber for damping movement of a wheel suspension system of a vehicle can include a damper tube, a piston, a damping adjustment assembly, and a protective cover. The damper tube can contain a fluid. The piston can be located in the damper tube so as to accommodate relative movement between the damper tube and the piston. The damping adjustment assembly can be connected to the damper tube, and can include a reservoir, a solenoid valve, and a wire harness connection. The solenoid valve can be in fluid communication with each of the reservoir and the damper tube and configured to selectively open and close fluid communication between the reservoir and the damper tube. The wire harness connection can be in electrical communication with the solenoid valve. The protective cover can contain the wire harness connection.

Provided is an on-demand shock stiffening system. The on-demand shock stiffening system operates to immediately stiffen the shocks in response to a user activating the system. The system may include a main body with an oil flow aperture and a flow control system that operates to restrict the flow of oil between the reservoir and the shock. The on-demand shock stiffening system may be coupled between the reservoir and the bridge of the shock and operates to restrict flow of the oil in order to stiffen the shock immediately in an on-demand manner.

A damper with inner and outer tubes and a piston slidably disposed within the inner tube to define first and second working chambers. A fluid transport chamber is positioned between the inner and outer tubes. A collector chamber is positioned outside the outer tube. An intake valve assembly, abutting one end of the inner tube, includes first and second intake valve bodies and a divider body, which define first and second intermediate chambers in the intake valve assembly. An accumulation chamber is positioned between the intake valve assembly and a closed end of the outer tube. The first intermediate chamber and accumulation chamber are arranged in fluid communication with the collector chamber. A first intake valve controls fluid flow between the second working chamber and the collector chamber. A second intake valve controls fluid flow between the second intermediate chamber and the collector chamber.

An active control anti-yaw damper (100) is provided. When a piston (2) of the active control anti-yaw damper (100) reciprocates inside a hydraulic cylinder (1), an interior of the hydraulic cylinder (1) is divided into two cylinder blocks (PA, PB) which communicate with an oil reservoir through two main oil lines respectively to form a primary loop between the hydraulic cylinder (1) and the oil reservoir; a reversing valve (PV3) is installed between the two main oil lines and the oil reservoir and is configured to change a flow direction of the primary loop when the active control anti-yaw damper (100) is in an active mode and adjust a displacement of the piston (2) within the hydraulic cylinder (1).
