Chevy SB Water Pump Pulley Kit Serpentine

The Chevy SB Water Pump Pulley Kit Serpentine from MARCH PERFORMANCE is designed for small-block Chevy V8 engines that require a modern serpentine belt drive upgrade. This aluminum pulley kit replaces outdated mechanical systems with a more efficient, belt-driven design that enhances engine efficiency. Builders restoring or upgrading classic Chevy V8 applications will appreciate the reliable performance this kit delivers in street rods, muscle cars, and hot rods.

This water pump pulley features a 5.25-inch diameter with six-rib serpentine grooves, designed to work seamlessly with modern serpentine belt systems. Constructed from lightweight aluminum, the pulley resists corrosion while reducing rotational inertia on the water pump shaft. The clear powder coat finish protects against oxidation and ensures durability for continuous cooling system operation.

Enthusiasts performing serpentine belt conversions on small-block Chevy engines will find this kit compatible with standard V8 mounting points, making installation straightforward for both professional shops and experienced DIY builders. The compact design (6.3 x 4.6 x 6.4 inches) ensures fitment in tight engine compartments, and the lightweight 1.2-pound aluminum construction minimizes added weight.
