Water Pump Pulley - GM LS

The Edelbrock Water Pump Pulley for GM LS-series engines is a precision-engineered serpentine pulley designed to optimize coolant circulation and accessory drive efficiency. This pulley is essential for LS engine builders and restorers who require reliable water pump drive compatibility.

Constructed from lightweight aluminum, this pulley features a black anodized finish that resists corrosion while maintaining a clean engine bay appearance. Its smooth serpentine design reduces friction and heat generation compared to ribbed alternatives, translating to improved cooling system efficiency and reduced parasitic drag on the engine.

Whether upgrading a stock cooling system, rebuilding an engine, or standardizing accessory drives on a custom build, the Edelbrock pulley ensures reliable coolant flow without modification to existing brackets or tensioners. Its direct fitment on LS-series water pumps makes it the go-to choice for technicians and enthusiasts alike.
