Clutch Masters Flywheel Friction Lock Tool

The Clutch Masters Flywheel Friction Lock (FFL) is a thin friction shim, also called a flywheel surface lock. It installs between the flywheel and the crankshaft flange to help keep the flywheel from loosening. This matters most in high-horsepower street and racing engines.

Key Features:

• Diamond-grip construction: A nickel-coated steel substrate holds partially embedded diamond particles. The particles bite into both the flywheel and the crank flange.
• Crankshaft protection: A flywheel that comes loose can fret (weld) itself to the crank and damage it. The FFL adds a hard steel layer that helps prevent this.
• Higher torque capacity: Clutch Masters states that the FFL can handle up to 5x higher shear forces and transmit up to 5x higher torque than conventional systems, with no other modifications.
• Minimal added thickness: The installed thickness is about .006"-.009", so it does not significantly change assembly spacing.
• Easy to install: It goes in during flywheel installation and can be reused after disassembly.

Clutch Masters is a well-known clutch and drivetrain brand. This tool is a simple, cost-effective way to add security to a flywheel and crank interface. It suits performance builds, track cars, and tuned daily drivers.
