Fitment Notes

Installs between the flywheel and crankshaft; intended for use alongside a clutch installation or service

Features

Nickel-coated steel substrate with partially embedded diamond particles for extreme surface friction
Developed using 3M friction shim technology engineered specifically for flywheel applications
Helps prevent flywheel-to-crankshaft fretting (welding) if the flywheel comes loose
Capable of handling up to 5x higher shear forces than conventional setups
Transmits up to 5x higher torque without additional modification
Thin .006"-.009" installed thickness does not significantly alter assembly spacing
Easy to install and reusable after disassembly
Protects against costly crankshaft damage from a loose or fretted flywheel

Specifications

1x Flywheel Friction Lock

Product Description

The Clutch Masters CM-037-FFL Flywheel Friction Lock is a thin friction shim that installs between the flywheel and crankshaft to protect against one of the more costly failures in high-performance Honda and Acura applications: a flywheel coming loose and fretting (welding) itself to the crank. Developed using 3M friction shim technology specifically for flywheel use, it features a nickel-coated steel substrate with embedded diamond particles that bite into both surfaces for dramatically increased grip.

At an installed thickness of just 0.006"-0.009", it doesn't meaningfully change assembly spacing, making it a simple add-on during clutch or flywheel service. Rated to handle up to 5x the shear force and torque of a conventional setup, it's a relatively low-cost form of insurance for anyone running a tuned or track-driven engine where a loose flywheel could mean a destroyed crankshaft.
