Underdrive Pulley Kit, 85-87 CamaroItem no longer available!!!
Billet Steel pulleys from March offer increased acceleration and gas mileage by underdriving the power steering, air pump, and the AC pump. The smaller crankshaft pulley in this kit slows down the rpm of these accessories to reduce the amount of energy they consume. An alternator pulley is also included with the kit to keep the charging system working at full capacity. This is a very easy and inexpensive way to gain 10-15hp. Kit fits 85-87 Camaro/Firebird.
