The Alternator Pulley 20T Radius Tooth by MOROSO is designed for builders and mechanics focused on optimizing serpentine belt drives in high-performance engine builds. This 20-tooth pulley serves as a replacement for OEM alternator pulleys in custom engine configurations and retrofit applications where alternator speed ratios need adjustment.
The radius tooth design ensures compatibility with serpentine belts and enhances load distribution, which helps reduce slippage and heat buildup during high-RPM operation. Weighing just 0.26 pounds, this lightweight pulley minimizes rotational inertia, improving throttle response and reducing parasitic drag on the crankshaft, making it particularly beneficial for naturally aspirated applications.
Engine builders and technicians can rely on MOROSO pulleys for various applications, including Chevrolet small-block and big-block platforms, Mopar applications, and Ford Windsor builds. The 20-tooth configuration allows for precise gear ratio selection when paired with compatible crankshaft and water pump pulleys, enabling users to fine-tune alternator output voltage and belt tension parameters.
