Pulley Water Pump HTD 36 Tooth Deep

The Pulley Water Pump HTD 36 Tooth Deep from Jones Racing Products is a precision-engineered cooling system component designed for high-performance engine builds and racing applications. Built for users who demand reliability in demanding thermal management scenarios, this HTD pulley delivers consistent power transmission between the water pump and engine crankshaft, ensuring optimal coolant circulation under extreme operating conditions. Whether you're running a modified street engine or a full competition build, proper pulley synchronization is critical to preventing thermal stress and extending engine longevity.

This water pump pulley features a HTD (High Torque Drive) tooth profile with 36 teeth, designed to mesh securely with matching HTD belts and maintain precise timing under load. The deep groove design accommodates 2-1/4 inch wide belts, providing increased contact surface area and grip compared to standard pulleys—essential for high-horsepower applications where belt slip cannot be tolerated. Constructed from aluminum and finished in black anodize, the pulley resists corrosion while maintaining a professional appearance; the anodized coating also improves heat dissipation properties. The 4-bolt mounting pattern ensures universal compatibility across most engine platforms, and the shaft accepts both 5/8 inch and 3/4 inch diameters, eliminating guesswork during installation. Weighing just 0.48 lbs, this compact component (4.45 x 3.1 x 5.25 inches) integrates seamlessly into tight engine bays without adding unnecessary mass.

Experienced engine builders and performance technicians rely on Jones Racing Products pulleys for consistent synchronization in serpentine and dedicated cooling belt systems. This HTD 36 Tooth Deep pulley works best in applications requiring predictable gear ratios and positive belt engagement—particularly LS-based engines, small-block builds, and racing platforms where thermal management directly impacts performance. Installation requires confirming shaft diameter (5/8 or 3/4 inch) before ordering; verify your current water pump shaft specification and belt width compatibility to ensure proper fitment. The universal 4-bolt pattern accommodates most standard water pump housings, though fitment verification is recommended for exotic or heavily modified platforms.
