Upgrade your Small Block Chevy to a true serpentine pulley system. Our complete kits convert your engine to true serpentine function where a single 6-rib or 8-rib belt and tensioner work in unison. All system include modern brand name accessories. The result is more amps, better cooling, improved steering feel, modern air conditioning and improved reliability. All kits are compact, easy-to-install, and come loaded with features that will make your ride stand out from the crowd and perform like a champ. If you prefer old school adjustable brackets rather than true serpentine, check out our old school, dual belt Basic Series system.
