Perrin Alternator Pulley for FA / FB Engines (Black) - Subaru BRZ / Toyota GR86 2022+

Description

Decrease rotational mass and dress up your engine bay with the PERRIN Alternator Pulley!

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.
