The supercharger isolator is part of the supercharger drive assembly and is located in the supercharger snout. The OEM isolator installed at the factory contains a spring mechanism and is notorious for noise and a short service life. The spring in the original isolator wears a groove on the supercharger shaft, creating debris that will eventually cause the shaft seal to fail. This replacement coupler is manufactured by the Eaton Corporation for GM, and as an OEM part that installs as a direct replacement for the original.
