Jones Racing Products Serpentine Water Pump Pulley Diameter

Jones Racing Products Serpentine Water Pump Pulleys are lightweight, billet aluminum pulleys made for high-performance and racing engines that use a serpentine (poly-V) belt drive. Each pulley is a universal-style water pump pulley that fits 5/8 in or 3/4 in water pump shafts. It works well for engine builders who want to fine-tune water pump speed, cut rotating weight, and keep belt drive performance consistent.

Key Features:

• Billet aluminum construction keeps rotating weight low while staying strong
• Black anodized finish helps resist wear and corrosion
• Serpentine (poly-V) rib profile for smooth, reliable belt engagement
• Extra groove on the pulley helps with belt alignment during installation
• 4-bolt mounting pattern
• Fits 5/8 in or 3/4 in water pump shafts
• Each pulley is sold individually
