The Chrome-Molly Forging allows fewer opportunities for failure and promotes uniform, efficient heat transfer from the clutch disc. This is to prevent warped friction inserts or loose ring gears. It is strategically lightened, stronger, safer and has better thermal capacity than OE cast flywheels. With smooth operation at all RPMs, these flywheels meet the needs of both the enthusiast and the hardcore racer.
