Replace the original supercharger pulley on your CTS-V with this precision-made 2.55″ overdrive unit to make an additional 3-4 pounds of boost and more horsepower and torque.

This pulley is a one-piece unit that is CNC-machined from high grade steel.  The center bore is sized for the appropriate interference fit and no pinning or drilling is necessary for installation.  The finished pulley is powdercoated in a semi-gloss black for long lasting surface protection.

We recommend the installation of Metco MIP-100V idler pulley on applications using overdrive (smaller) supercharger pulleys. We also recommend the installation of the Metco solid supercharger drive isolator LSA0001.

Note:  A shorter supercharger belt is necessary when this overdrive supercharger pulley is installed when using the factory idler, if using the MIP-100V idler the stock length belt can be used.
