March Performance Late GM serpentine pulley kits reduce accessory drag, which creates about 12.5 hp at the rear wheels and eliminates belt throwing. These pulley kits are designed for normal street driving. They're available in either 2-piece steel or 3-piece aluminum kits. The aluminum sets are precision CNC-machined from 6061 T-6 billet for extra strength, long wear, and to run perfectly true. They are hand-polished and covered with a maintenance-free clear powdercoated finish. They're also hard coated and reinforced in areas of high stress and wear. The steel sets are precision CNC-machined from high-carbon billet steel, coated with iron phosphate, and then covered with a high-gloss black polyester powdercoating for maximum rust prevention.
