High-Friction Diamond-Embedded Shims: A Breakthrough for Crankshaft Connection Integrity in High-Output Engines
Designed for high-performance powertrains, these precision-engineered interface components solve the critical problem of micro-slip and torque loss at the crankshaft-to-flywheel/flexplate joint under extreme loads.
Utilizing a proprietary process that uniformly embeds diamond micro-particles into the substrate, the shim achieves a step-change in surface friction within an ultra-low profile of just 0.005 inches. This technology delivers a 3 to 4x increase in both static and dynamic coefficients of friction compared to conventional bare metal contacts.
This dramatic increase in frictional capacity significantly enhances the joint's safety margin, making it indispensable for high-performance engine builds where peak torque exceeds 500 ft-lb or RPM surpasses 9,000. It is the ideal solution for race-tuned engines, forced induction upgrades, and track-day durability. Engineered for broad compatibility, the shim integrates seamlessly with both manual and automatic transmission systems without any modifications to OEM mounting hardware or fastening specifications—a truly "install and drive" solution.
Currently validated for the DSM platform (1990–1999 Mitsubishi Eclipse, Eagle Talon, Plymouth Laser) , it installs directly between the factory crankshaft and flywheel/flexplate, serving as the critical link for maximum drivetrain reliability.
