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.
Application: 1988-1991 Chevy Corvette Small Block. Kit includes: 4101-08 6-rib Crank Pulley (5.875") 4102-08 Non-rib Water pump Pulley (6.5") 110-08 6-rib Alternator Pulley (1.75") All Mounting Hardware.
