Note: The installation of Metco Motorsports parts or any aftermarket parts may affect your vehicle's warranty, if applicable. Check with your dealer for details. Vehicles included in GM's supercharger recall (and vehicles with build dates 4Q 2014 and later) should already be fitted with this same solid isolator.
The supercharger isolator is part of the supercharger drive assembly and is located in the supercharger snout. The original isolator as 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. Our replacement coupler is manufactured by the Eaton Corporation for GM, and as an OEM part it installs as a direct replacement for the original. This isolator is not susceptible to the issues associated with the original unit.
We highly recommend replacing the original isolator with this upgraded unit when an overdrive supercharger is installed on the car.
Image 4 (above) shows an isolator (differs from actual) mounted to the blower shaft at the end opposite the supercharger pulley.
