Clutch Masters CM-140-FFL Flywheel Friction Lock
The Clutch Masters CM-140-FFL Flywheel Friction Lock installs between the flywheel and crankshaft on compatible BMW vehicles. It uses a nickel-coated steel substrate with embedded diamond particles from 3M to bite into both surfaces and prevent loosening. This setup handles up to 5 times higher shear forces and transmits up to 5 times higher torque than standard setups without other changes.
