The Alternator Pulley HTD 24 Tooth by Jones Racing Products is a precision-engineered serpentine drive component designed for high-performance automotive applications where reliable belt synchronization and consistent power delivery are critical. This product is ideal for automotive enthusiasts and professional mechanics who require accuracy in engine accessory drive systems.
The HTD (Synchronous) pulley eliminates slip common to V-belt designs, ensuring your alternator charges at predictable rates under dynamic engine conditions. Utilizing a positive tooth engagement mechanism, this pulley prevents belt slippage that can occur during aggressive throttle application or high engine RPM operation. The compact design—measuring 3.2 x 1.55 x 4.5 inches and weighing only 0.21 lbs—minimizes inertia and heat buildup while maintaining the structural rigidity required for prolonged high-RPM service.
This 24-tooth configuration offers a specific gear ratio that optimizes belt tension and alternator shaft speed relative to crankshaft rotation. It is particularly beneficial for high-performance engines, LS swaps, and restomod projects, providing the repeatability needed for carburetor tuning, fuel injection calibration, and electrical load management.
