Pulley Crankshaft HTD 20 Tooth 1in Wide

The Jones Racing Products Pulley Crankshaft HTD 20 Tooth 1in Wide is a precision-engineered serpentine pulley system designed for marine and automotive engine synchronization. Built from aluminum with black anodized coating, this HTD pulley delivers reliable belt tension control and repeatable timing in high-vibration environments where consistent crankshaft engagement is critical to engine performance.

The 20-tooth HTD profile with 8mm pitch indexing ensures positive power transmission without slippage, essential for applications requiring stable accessory drive performance. The 1-inch mandrel diameter accommodates standard crankshaft mounting hardware, while the 1/8-inch keyway provides positive rotational lock. Weighing just 0.16 lbs, this pulley minimizes rotating mass and inertial stress on bearings—a critical factor in high-RPM marine engines where even small weight reductions improve responsiveness and reduce fatigue loads on the crankshaft.

This HTD crankshaft pulley is engineered for builders and technicians working on engine swaps, racing applications, or marine propulsion systems where OEM pulleys don't fit custom configurations. The universal mounting interface allows integration into non-standard engine builds without modification. Black anodized aluminum resists saltwater corrosion better than bare aluminum—important for offshore installations—while maintaining the lightweight properties required for high-performance setups.

Jones Racing Products is recognized for precision-ground pulleys used in both street and competition environments. The HTD 20-tooth specification is a workhorse profile offering broad compatibility with aftermarket belt systems and serpentine configurations.
