The Maximum Motorsports Jo04B7 Water Pump Pulley Kit is an excellent upgrade for Chevy Big Block engines with crankshaft-driven water pumps, specifically those with displacements of 396, 427, and 454 cubic inches. This kit is manufactured by Maximum Motorsports, a well-known and trusted name in the automotive performance industry.

The Jo04B7 kit comes with a high-quality, billet aluminum pulley that replaces the factory plastic pulley. This upgraded pulley offers several benefits over the stock part. First and foremost, it is made of more durable material, ensuring a longer service life and improved reliability.
