March Performance 1979-93 5.0L Ford Pulley Kits

March Performance 1979-93 5.0L Ford pulley kits are designed for normal street driving. They reduce accessory drag, which typically creates about 12.5 HP at the rear wheels and eliminates belt throwing. These 3-piece pulley kits are available in both aluminum and steel sets. Aluminum sets are machined from 6061-T6 billet aluminum for extra strength. They are hand-polished and then covered with a "no polishing" clear powdercoated finish. They're also given a durable hard coating on the crank pulley to prevent oil seal leaks, and on the water pump pulleys to prevent premature wear. Steel sets are made from high-carbon steel, precision-machined to run perfectly true. They are coated with iron phosphate, and then given a high-gloss black polyester powdercoating for maximum rust prevention. Show Less
