Description

The OEM Subaru Alternator Pulleys may fail over time. Help prevent this from happening with the PERRIN Alternator Pulley.

The OEM Subaru Alternator Pulley 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.

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.

Designed to match the PERRIN Crank Pulley, the precision-machined grooves tightly sync with all OEM and aftermarket belts.

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.
