LIVERNOIS MOTORSPORTS 2.55" 8 RIB SUPERCHARGER PULLEY 2009-2015 CTS-V & ZL1
- Product Information
- Vehicle Fitments
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.
