MCD Internal By-Pass Shock System Maintenance and Assembly

Another Ground-Breaking Innovation by MCD
Developed in two years and approved in 2017 European Championship the new Two Way Internal By-Pass Shock System is now ready to meet our enthusiasts. Our new coilover shock system is the first manufactured design in large scale off-road category.

During compression the main piston moves all amount of oil to the transfer tunnel, the oil than moves through the compression needle valve and recirculates between the two cylinders and move back behind the piston. The particular piston only allows oil flow through the shim during high speed compression. This allows precise control over damping. During rebound the main piston moves all amount of oil to the transfer tunnel, the oil than moves through the rebound needle valve and recirculates between the two cylinders and move back above the piston. The compression and rebound circuit feature auto-adaptive dual-way check valves that allow the oil to by-pass freely on each other independently.

It is two-way adjustable providing a wide range of easy adjustment possibility. By CNC machined billet alloy valve block two-way valves you can adjust the shocks while on the car. These adjustments provide optimum driving capabilities and great handling. Due to usage of super light-weight oil, the driver secures a constant performance in diverse wheather conditions whether hot or cold.
The shocks are available in three different length. 64mm, 47mm and 26mm stroke depending on the car type.
