RPC’s super lightweight Chromoly flywheels are made from 4140 one-piece billet Chromoly steel. They are specifically designed to reduce weight and inertia for better engine response, leading to faster overall gear changes and throttle blips. This flywheel incorporates special design features to enhance the airflow which improves the cooling of the clutch and flywheel.

The ring gear teeth are milled onto the flywheel, unlike an aluminium flywheel where the ring gear is pressed onto the flywheel which has the possibility of separating from the flywheel. All RPC Chromoly flywheels have passed engineering tests to 12,000 rpm. After professionally installed the flywheel requires a 500 mile break-in period. Ultra heavy-duty and meets or exceeds SFI 1.1 specification Made from 4140 forged Chromoly steel, making this roughly 2 times stronger than billet steel.
