Motion Control Suspension | Motorsport & Premium Dampers


The MCS 2W damper is a double-adjustable damper with external reservoirs which allow for adjustment of the gas pressure in the damper. Both compression and rebound damping forces are independently adjustable with the compression adjuster located on the reservoir head and the rebound adjuster located on the shaft-end.

Compression damping forces are controlled by a large blow-off valve located directly on the reservoir main piston for the most precise and accurate damping control, and not a needle valve with a smaller effective adjustment range before the needle is too far out of the orifice to influence flow.

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. Utilizing orifices introduces the ability to have a wide operating range, avoiding pesky re-valves, consistency in damping adjustment per click, and virtually eliminates fatigue with usage.

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.

Remote reservoirs give superior fluid temperature control and are available (or standard depending on application) with Staubli dry-breaks for easy installation.

The MCS 2W damper is a double-adjustable damper with an adjustment range of 18 clicks of compression and 18 settings of rebound. Application specific valving covers a wide range of spring rates and eliminates the need to constantly revalve every time you want to increase or decrease your spring rate. MCS has engineered its adjustment mechanisms so each click can be felt, but never feels like you’ve gone too far. 2W dampers are built standard with a linear piston and a digressive piston option is available.

18 Clicks of Compression Adjustment

Compression damping is easily manipulated on the 2W damper. With 18 clicks of compression control, the user can easily introduce more platform to the vehicle to make better use of their mechanical contact patch, resulting in faster lap times.

18 Clicks of Rebound Adjustment

With 18 clicks of rebound adjustment, the user can easily introduce more spring control or change the balance of the car.

Gas Pressure Adjustment

Schrader valves are fitted on the ends of the reservoirs. This introduces a valuable tuning tool – the ability to increase or decrease the nitrogen pressure in your damper, 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 generates large loads or to allow more weight transfer to generate more traction in low grip scenarios.

Compression Adjuster Knob.

Connected to the internal compression adjustment mechanism. Allows user to change compression damping forces easily.

Compression Main Piston Assembly

Contains proprietary internal adjustment mechanism for compression damping forces.

Dividing Piston

Separates the gas cavity from the oil cavity.

Schrader Valve

Make gas pressure changes easily with a shock tool.

Rebound Adjustment Mechanism

Proprietary adjustment mechanism to manipulate rebound damping forces.

Main Piston Assembly

Generates overall valving range. Valving can be manipulated by changing the non-preloaded shim stack configuration on the compression and rebound sides of the piston.

Support Piston

Provides additional lateral support on piston end of shaft assembly.

Shaft Guide

Creates additional lateral support on shaft-end side of shaft assembly.


Also known as piston rod. Responsible for displacing fluid in the damper body to be controlled by piston assembly and adjustment mechanism. We utilize 22mm diameter shafts for strut applications and 16mm diameter for shock applications on the 1WNR damper system.

Rebound Adjuster Knob

Connected to the internal rebound adjustment mechanism and allows user to change rebound damping forces easily.

Buyer's Guide

We have a broad range of damper systems available, ranging from a single adjustable system, to a triple adjustable system with remote reservoirs. No matter which MCS system you choose, you can expect to achieve faster lap times, better tire wear and a system that will grow with you as both driver and car progress. MCS provides consultation for consumers, allowing them to make an educated decision as to which damper system will best fit their goals.
