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: Black. Application: 1988 - 1997 Chevrolet C/K 2500 & 3500 Trucks (7.4L V8 454 ci); Crank Pulley Retained by 3 Bolts Only. Kit includes: 4361 6-rib Crank Pulley (5.9") 4012 Non-Rib Water Pump Pulley (5.7") 112; Single 6-rib Alternator Pulley (2 11/16") All Mounting Hardware.
