March Performance Chevy Big Block Ultra Drive Custom Serpentine Kits

March Performance Chevy Big Block "Ultra Drive" custom serpentine kits are designed for mounting accessories below the valve covers and in-between the width of the heads. They're a low-cost alternative to the Deluxe and Ultra Series that give up nothing in performance. These components are precision CNC-machined from 6061-T6 aluminum for strength and perfect fit. The pulleys will not fracture like common cast pulleys, since they have high tensile strength for much longer wear—and are hard-coated for extra durability. Custom kits feature: * Sanden air conditioning compressor * 140 amp alternator * Edelbrock aluminum reverse rotation short water pump * Maval Type 2 power steering pump (except where noted) * Dayco spring loaded tensioner * Air conditioning bracket * Alternator bracket * Billet power steering bracket (except where noted) * Crank pulley * Hard-coated water pump pulley with fairing * Alternator pulley with machined fan * Billet power steering and tensioner pulleys * Wing cross emblem * Air conditioning line fittings * Grade 8 mounting hardware * Most components available in clear or black powdercoat finish Show Less
