Matching our signature Crank Pulley design, the PERRIN Alternator Pulley decreases rotational weight while maintaining good looks.
Decrease Rotational Mass - PERRIN Alternator Pulleys weigh just 0.116 lbs., which is lighter than the OEM alternator pulley. Throttle response, horsepower, and torque are all increased with this easy-to-install part.
Design - Designed to match the PERRIN Crank Pulley, the precision-machined grooves tightly sync with all OEM and aftermarket belts.
Construction and Finish - The PERRIN Alternator Pulley is machined from 6061T6 billet aluminum, anodized black, blue, or red, and laser etched for increased belt life and a precision fit.
