Chrome Steel Water Pump Pulley Long SBC 6.3 Dia

The Chrome Steel Water Pump Pulley Long SBC 6.3 Dia is a precision-engineered component designed for small-block Chevrolet (SBC) engine builds where reliable coolant circulation and durability are non-negotiable. This single-groove V-belt pulley serves as the driven component that transfers engine rotation to the water pump, maintaining optimal cooling system performance in street, bracket racing, and restoration applications. Whether you're rebuilding a vintage 350 or upgrading a modern SBC swap, this pulley ensures consistent water pump engagement and thermal management.

Manufactured by Racing Power Co-Packaged, this water pump pulley features a full chrome plating over steel construction, delivering both corrosion resistance and a professional appearance under the hood. The 6.3-inch diameter and long-style design accommodate standard SBC water pump configurations and integrate seamlessly with serpentine or traditional V-belt drive systems. Chrome plating protects against rust and oxidation while the steel core maintains structural integrity under the repeated stress of belt tensioning and rotational forces, ensuring years of reliable service without slippage or premature wear.

SBC enthusiasts, engine builders, and restoration specialists rely on this pulley for stock-replacement or performance cooling upgrades. It is compatible with long-style water pump housings common to small-block Chevrolet applications and works with both carbureted and fuel-injected configurations. Installation is straightforward: simply bolt the pulley to your water pump shaft, align with the harmonic balancer and alternator pulleys, and adjust belt tension for optimal contact. The compact 8.8 x 2.1 x 12-inch footprint and light 1.28-pound weight make handling and installation efficient, while the single 1-groove design ensures compatibility with standard SBC serpentine or V-belt packages.
