2009-2015 CTS-V, 2012-2015 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 high-grade 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 rear of the pulley hub incorporates the same raised flange as the original pulley to facilitate the proper 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 as shown. The pulley cover is machined to accept the original plastic pulley cap (not included) for a completely stock-appearing installation.
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. Machining of the snout is not required for the installation of our supercharger pulleys, including the 2.40" size.
Important Note: Our pulley hub is a unique design that allows the installation of the stock-appearing front pulley cover. However, if removal of this pulley hub becomes necessary for some reason, it cannot be removed without damage to the hub. Pulley hubs can be purchased separately if necessary.
Note 1: 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).
Note 2: For proper installation, the upper portion of the supercharger must be removed from the vehicle and the blower snout separated from the case. A dedicated pulley tool can be used to remove the original pulley, but a press is required for the installation of the replacement pulley. As part of this changeover, we highly recommend replacing the original supercharger coupler if your vehicle is still equipped with the problematic spring-loaded unit. Our isolator is the same solid unit offered by GM in the upgraded LSA superchargers.
