Alternator Drive Pulley 32 Tooth HTD

The Alternator Drive Pulley 32 Tooth HTD by JONES RACING PRODUCTS is a precision serpentine pulley system component engineered for high-performance engine builds and custom automotive applications. This HTD (High Torque Drive) 32-tooth pulley synchronizes power delivery from your crankshaft to the alternator, ensuring consistent belt tension and efficient charging system operation across the entire RPM band. Whether you're building a turbo application, upgrading to a larger displacement engine, or fine-tuning your accessory drive ratio, this pulley gives you the control to optimize both alternator output and parasitic drag.

HTD profile pulleys deliver superior grip and load transfer compared to standard V-belt designs, eliminating slip under boost or high-torque conditions. The 32-tooth profile is sized to work with complementary crank and water-pump pulleys in comprehensive serpentine kits, allowing you to dial in exact gear ratios for your charging and cooling demands. Manufactured to strict Jones Racing Products tolerances, this lightweight pulley—weighing just 0.26 lbs—minimizes rotational inertia while maintaining the rigidity needed for sustained high-RPM use. The compact 3.75-inch outer diameter integrates cleanly into modern and classic engine bays alike.

This pulley suits builders upgrading late-model LS, small-block Chevy, Ford, and Mopar platforms with aftermarket alternators or dual-serpentine configurations. HTD belt systems are increasingly favored in competition and street applications because they prevent the slippage that can occur in high-load scenarios—critical when you're running heavy electrical loads or a multi-belt drive arrangement. Installation requires a matching HTD crankshaft pulley (typically 54 to 72 teeth) and compatible belt; verify your entire accessory drive specification before ordering to ensure proper tension and alignment across all components.
