March Performance Chevy Small Block "Ultra Drive" custom serpentine kits are designed for mounting accessories below the valve covers and in-between the width of the heads. These kits are a low-cost alternative to the Deluxe and Ultra Series that give up nothing in performance. Their 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 * GMB aluminum reverse rotation 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 * Power steering and tensioner pulleys * Wing cross emblem * Air conditioning line fittings * Grade 8 mounting hardware * Some models include power steering pump
