Weighing only a mere 3.2KG, RPC 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. Most incorporate special design features to enhance the air flow to improve the cooling of the clutch. 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 (2X stronger than billet steel).
RPC Lightweight Chromoly flywheels incorporate special design features to enhance the airflow for improved clutch cooling. RPC Lightweight Chromoly flywheels work with every clutch including Exedy, ACT, Fidanza, Clutchmasters, and other OEM clutch kits CAD designed, CNC machined and computer balanced.
