Chevrolet Performance 19421448 Accessory Drive System:
- Fits most non-LSA and non-LS9 (non-supercharged) engines
- The high-mount compressor bracket is an original Chevrolet Performance component but was not part of Corvette production usage
- This package is designed to provide a complete serpentine belt accessory drive system that will clear most frame rails
- This kit is loosely based on the accessory drive system from 2005-2013 Chevy Corvettes
- Uses factory-engineered brackets and a GM belt tensioner to maintain proper belt tension during operation
