Prevent Future Failure

Subaru models with OEM clutch-style alternator pulleys may fail over time. This failure can lead to knocking noises, battery charging issues, belt wear, and cause belts to become extra jumpy. The PERRIN Alternator Pulley removes this future failure point.

Decrease Rotational Mass

PERRIN Alternator Pulleys weigh just 0.20 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 & 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.
