Description

Supercharger Pulley

2009 & Newer CTS-V, 2012 & Newer Camaro ZL1

Replace the original supercharger pulley on your CTS-V or ZL1 with one of our precision-made overdrive units to make as much as 5.5 pounds of additional boost for more more horsepower and torque.

Our LSA supercharger pulleys are a three-piece design, utilizing a precision-machined steel pulley hub and an interchangeable aluminum ring and front cover.  The center bore of the pulley hub is sized for the appropriate interference fit and no pinning or drilling is necessary for installation.  The pulley ring and stock-appearing front cover are black-anodized for long lasting surface protection, and the steel pulley hub is nickel-plated (not shown).

Like other Metco Motorsports supercharger pulleys, the interchangeable design allows for easy boost level changes.  Once the pulley hub is installed on the supercharger, the pulley rings (and pulley covers) can be purchased separately and easily changed.

We recommend the installation of our MIP-100V idler pulley (listed elsewhere in this section) on applications using overdrive (smaller) supercharger pulleys.

Note 1:  While the original belt can be re-used with the 2.85″ pulley, a shorter supercharger belt is necessary when the 2.40″ or 2.50″ overdrive supercharger pulley is installed.  The Gates or NAPA 080653 in the premium Greenstripe line, is recommended (0.7″ shorter than stock).  If this pulley is installed in conjunction with our MIP-100V idler and the 9.55″ pulley ring, a 68.5″ belt is recommended.

Note 2:  The end of the supercharger shaft on the LSA application is not threaded like it is in other applications, so a standard pulley removal and installation tool cannot be used.  The supercharger snout must be removed from the supercharger case and the original pulley must be removed and the new pulley installed using a press or a suitable pulley tool.  No gaskets need to be replaced and generally no lubricant is lost during this procedure.  As part of this changeover, we highly recommend replacing the original snout isolator, which is problematic and prone to make noise.  Our solid isolator is precision-machined from very high grade materials and installs as a direct replacement for the original.
