Lightweight SFI 1.1 Approved Chromoly Steel Flywheel

The Exedy Lightweight Flywheel (HF01) is engineered to significantly reduce rotational mass and inertia, leading to quicker engine revving and improved throttle response for drag racing, autocross, rally events, and street use. It is constructed from a robust, solid one-piece billet chromoly steel forging, ensuring superior strength and durability compared to other materials. The design incorporates special features to enhance airflow, which helps to keep the clutch operating cooler. Unlike some aluminum flywheels, the Exedy HF01 has integrated ring gear teeth, eliminating the risk of separation due to differing expansion rates. This flywheel has undergone rigorous engineering tests and is rated to withstand speeds between 15,000 and 18,000 RPM, guaranteeing its integrity up to these limits. It proudly carries SFI 1.1 approval, signifying its certification for use in competitive motorsports. Key features include a billet chromoly steel construction, a product weight of 9.5 lbs, and a high RPM rating. Benefits translate directly to a more responsive engine, quicker revving capabilities, and a cooler-operating clutch thanks to the integrated fins for enhanced airflow. This product is specifically designed as a lightweight replacement for vehicles originally equipped with OE dual mass flywheels. Applications for this specific model include the 1999-2000 Honda Civic, 1990-2001 Acura Integra, and 1994-1997 Honda Civic del Sol. The product comes with a 60-Day Limited Warranty from Exedy.
