Designed for Small Block Chevy applications. 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.
This part number is configured as follows: Finish: Clear. Application: Chevy Small Block 5.625" Standard Rotation Short Water Pump. Kit includes: 6111 1 Groove Crank Pulley (7") 6012 1 Groove Water Pump Pulley (6 1/4") 137; 1 Groove Alternator Pulley (2 11/16") All Mounting Hardware.
