EXEDY Racing Flywheels are made from solid one piece billet chromoly steel forgings. They are specifically designed to reduce weight and inertia for better engine response. Most incorporate special design features to enhance air flow to improve the cooling of the clutch. The ring gear teeth are milled onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel and have the possibility of separating from the flywheel.

Increased clamp loads give the necessary capacity to handle modified engines. This is the preferred clutch for street and light horsepower track use. Driveability is similar to the stock clutch. Pedal efforts will be slightly higher because of the higher clamp loads. All of our clutch discs have spring center dampers to reduce drivetrain shock.
