EXEDY Racing Clutch Lightweight Racing Flywheel (EF502A)

EXEDY Racing Clutch Lightweight Racing Flywheel (EF502A)Exedy flywheels combine low weight, low inertia and high thermal capacity. They are designed for lightly tuned racing cars and drag racing, autocross and rally events, as well as street usage. They are made from solid one piece billet chromoly steel or chromoly steel forgings. They are specifically designed to reduce weight and inertia for better engine response. Most incorporate special design features to enhance airflow and cooling of the clutch.

Exedy flywheels combine low weight, low inertia and high thermal capacity.  They are designed for lightly tuned racing cars and drag racing, autocross and rally events, as well as street usage. They are made from solid one-piece billet chromoly steel or chromoly steel forgings. They are specifically designed to reduce weight and inertia for better engine response. Most incorporate special design features to enhance airflow and cooling of the clutch. The ring gear teeth are integrated onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel and has the possibility of separating due to different expansion coefficients of aluminum vs. steel. Exedy steel billet and forged steel flywheels have passed engineering tests to 15,000-18,000 rpm and guaranteed not to fail to the said rpm and are all SFI approved.

Notes:

• SFI 1.1 Approved - Certified for use in Competitive Motorsports.

Features:

• Improve throttle response
• Allow the engine to rev more quickly
• Allow the clutch to operate cooler
• Burst tested and SFI approved
• No modification
• Accepts stock clutch disc and pressure plate
• Rated to 15000-18000 RPM
• Upgrade from OEM dual-mass flywheels
• Fins to enhance airflow and cooling

Removing weight from the flywheel is the single thing that will improve acceleration and throttle response more readily than any other single modification. Inertia is not your friend, and reducing rotational inertia will also improve critical throttle response, especially for road racing, rallying and autocrossing.

EXEDY's lightweight flywheels are made from a solid chromoly forging, with the ring gear machined as an integral part rather than being a separate piece that's pressed on. So there's no ugly possibility of the ring gear coming apart at speed, causing massive damage. That's why EXEDY Stage 3, 4 and 5 clutch kits include one of these flywheels. While most vehicles can benefit from a lightened flywheel, if your vehicle has a heavy, cumbersome dual-mass flywheel, you can replace it with an EXEDY lightweight flywheel. And save money at the same time, because replacing that dual-mass flywheel is an expensive item.
