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.
Pullies available in 2 sizes:
2.40" - +4.5-5.5PSI Boost
2.50" - +3.5-4.5PSI Boost
2.50 / 2.85 - K080653
