March Performance 4120-08 Black Aluminum Alternator & Crank Performance Series Pulley Kit
March Performance 4120-08 Black Aluminum Alternator & Crank Performance Series Pulley Kit Fits 1984-1987 Chevy Corvette Small Block
March Performance 1984-91 Corvette serpentine pulley kits eliminate belt throwing and create about 12-15 HP at the rear wheels by reducing accessory drag. They're available in 2 or 3-piece steel or aluminum kits with performance series pulleys for increased horsepower, or power and amp series pulleys for high amperage needs. Aluminum pulley kits are precision CNC-machined to run perfectly true and designed for daily street driving. They are made from 6061-T6 aluminum for extra strength and wear, and finished with a maintenance-free clear powdercoat. Steel pulley kits are precision CNC-machined from high-carbon billet steel, coated with iron phosphate, and then covered with a high-gloss black polyester powdercoat for maximum rust prevention.
