Exedy HF01 Chromoly Lightweight Flywheel for 1990-2001 Acura Integra and Honda Civic/del Sol

Fits 1990-2001 Acura Integra and select 1994-2000 Honda Civic Si and del Sol VTEC models. This Exedy HF01 lightweight flywheel is engineered to significantly reduce rotational inertia, delivering sharper throttle response and faster revving for street, autocross, and drag racing applications.

Unlike multi-piece aluminum flywheels with pressed-on ring gears that can separate under extreme thermal stress, Exedy flywheels are manufactured from a solid piece of billet chromoly steel or high-strength forgings. This monolithic design ensures the ring gear teeth remain an integral part of the flywheel for maximum safety and reliability. Each unit features a specialized design to enhance airflow, helping to cool the clutch assembly during aggressive driving. Every Exedy racing flywheel is SFI-certified and has passed rigorous engineering tests up to 15,000–18,000 RPM.
