March Performance 1994-95 5.0L Mustang pulley kits provide approximately 12.5 HP at 5,000 rpm and exude 13.6 ft.-lbs. of torque at 3,900 rpm. These 3-piece pulley kits are available in steel or aluminum. The steel sets are precision-machined to run perfectly true. They consist of high-carbon steel coated with iron phosphate, which is then covered with a high-gloss black polyester coating for maximum rust prevention. The aluminum sets are machined from 6061-T6 billet aluminum for extra strength. Then they are hand-polished, covered with a "no polishing" clear powdercoated finish, and hard-coated in high wear areas.
