The CVF Racing Reaper supercharged serpentine system is a billet aluminum dual-belt drive for the Chevy LT4 with its OEM supercharger. A dedicated 10-rib belt drives the supercharger, while a separate 8-rib belt runs the water pump, alternator, power steering and A/C.
The system uses billet brackets, billet spacers and stainless steel hardware, is CNC machined in the USA, and carries a CVF lifetime warranty. This version is finished in Stealth Black.
