This March Performance pulley kit replaces the factory crank, water pump and alternator pulleys with a matched set CNC-machined from 6061-T6 billet aluminum. Matched diameters keep the accessory drive working together, and the billet construction is lighter and stronger than stamped steel or cast pulleys. It is a straightforward bolt-on upgrade that also dresses up the front of the engine.
Kit includes: 4351-08 6-rib Crank Pulley (5.835") 120-08; Single 6-rib Alternator Pulley (2.625") All Mounting Hardware.
