The MCS 4W is quadruple-adjustable damper with an external reservoir. High speed compression, low speed compression, high speed rebound, and low speed rebound damping forces are independently adjustable. Gas pressure is also adjustable. The high speed compression and low speed compression adjusters are located on the remote reservoir head. High speed rebound and low speed rebound damping forces are independently adjustable from one very clever knob. With the knob in the “down” position, high speed rebound forces are adjusted. With the knob in the “up” position, low speed rebound forces are adjusted.
High speed compression damping forces are precisely controlled by a large blow-off valve located directly within the piston assembly in the remote reservoir head. Low speed compression damping forces are controlled through orifices located directly within the piston assembly in the remote reservoir head and allow for precise hydraulic control of damper oil.
High speed rebound damping forces are precisely controlled by a blow-off valve located directly directly within the piston assembly inside the damper body. Low speed rebound damping forces are controlled through orifices located at the main piston assembly in the damper body and allow for precise hydraulic control of damper oil through the main piston assembly
Gas pressure can be adjusted through a schrader valve located at the end of the remote reservoir, allowing you to increase or decrease the overall support to the vehicle. Reservoir pressure can be adjusted between 100 – 275 PSI to help support the platform in fast cornering that generate large loads or allow more weight transfer to generate more traction in low grip scenarios.
These dampers are packed with technical features but with an elegantly clean execution. The monotube design is very stable with more oil capacity and better heat dissipation than twin tube dampers. Large shafts give extremely high, low-friction side-load support unmatched by shocks inverted and converted for strut applications. The large main piston gives quick, accurate damper response and the divider piston separates oil and gas, eliminating cavitation which often causes noise and sloppiness. Utilizing orifices introduces the ability to have a very defined operating range, consistency in the damping force adjustment per click, and virtually eliminates fatigue with usage. Blow-off valves effectively manage high speed forces to maintain maximum mechanical grip.
