Engineered for strength and safety, the MF04 flywheel has been tested to withstand up to 18,000 RPM and holds official SFI certification for motorsport-grade reliability.
Enhanced airflow and cooling features help maintain optimal clutch temperature, reducing wear and extending component lifespan. Easy to install with a 6-bolt configuration, this flywheel fits seamlessly with factory specifications while providing noticeable performance gains. Whether used for competitive motorsport or spirited daily driving, the Exedy MF04 flywheel offers dependable strength, reduced inertia, and precision-engineered performance.
