The Clutch Masters 725 Series twin-disc street/race kit for 2008–2010 Chevy Cobalt SS ships with an aluminum flywheel and is a conversion that will not work with the OEM flywheel. It is built to be used exclusively with the Clutch Masters flywheel, providing a twin-disc solution for higher clamping capacity in demanding street or track applications where the correct flywheel is fitted.
