Action Clutch flywheels are designed and tested to ensure the best quality and performance. They are SFI certified, which meets the top performance standards in the automotive and motorsports industries. Engineered for street and race applications, Action Clutch chromoly flywheels offer three major benefits: Low weight, low inertia, and high thermal capacity. Made from durable one-piece billet chromoly steel or chromoly steel forgings, they are specifically made for light- to high-tuned racing cars that see drag racing, drifting, autocross, street use, and rally events, and specifically designed for a reduction in weight and inertia for better engine response. Each flywheel has gone through—and passed--engineering tests up to 15,000 to18,000 rpms, and are heat treated for extreme durability, saving you money by resurfacing multiple times.

Competition Clutch steel flywheels are made of 4140 forged steel and are one-piece designs, which helps significantly in reducing the chances of ring gear separation and friction surface warpage. Forged steel flywheels work with all performance and stock clutch assemblies, and can be resurfaced. Competition Clutch Ultra-lightweight steel flywheels are recommended for forced induction and/or track and rally racing applications. They are machined with less material to assist in quicker revving capabilities, and are well suited for Stage 3 and up clutch applications.

Exedy lightweight flywheels combine low weight, low inertia, and high thermal capacity. They're designed for light to moderately tuned racing cars for drag racing, autocross, and rally events, as well as street usage. The flywheels are made from solid one-piece billet chromoly steel or chromoly steel forgings. These replacements are specifically designed to reduce weight and inertia for better engine response. Most incorporate special design features to enhance the airflow, which improves the 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 from the flywheel due to the different expansion coefficients of aluminum and steel. Newly available are lightweight, solid replacements for vehicles fitted with OE dual mass flywheels. Exedy lightweight flywheels have passed engineering tests to 15,000-18,000 rpm. They're guaranteed not to fail to the said RPM, and are all SFI approved. * Material: All Exedu lightweight flywheels are made from either forged or billet chromoly steel. Chromoly is an abbreviation for "chromium-molybdenum steel" due to its property of incorporating alloy elements chromium and molybdenum. Thanks to this combination of materials, chromoly has an excellent strength to weight ratio and is considerably stronger and harder than standard 1020 steel or other aluminum flywheels on the market. * SFI certification: All Exedy Stage 1 Organic, Stage 2 Ceremetallic and Lightweight Flywheels carry SFI 1.1 Certification. Which means, when you buy these products, you can be confident they're certified for use in competitive motorsports. * Resurfacing Exedy flywheels: Resurfacing your Exedy lightweight flywheel during a clutch service is an ideal way to extend the life of your clutch and flywheel. Thanks to the nature and design of the Exedy flywheels, no special steps or tools are needed to perform the service. All you should do is follow the OEM service specifications to return your Exedy flywheel to "like new" condition.
