Description

The Perrin Alternator Pulley is crafted to enhance the performance and reliability of your 2022+ Subaru BRZ or Toyota GR86. Unlike OEM clutch-style alternator pulleys that are prone to failure over time, leading to knocking noises, battery charging problems, and belt wear, the PERRIN Alternator Pulley offers a robust solution. Constructed from 6061 T6 billet aluminum, this pulley is precision machined for a perfect fit and features tightly synced grooves compatible with both OEM and aftermarket belts. Its anodized finish is available in black, blue, or red, and it is laser etched for increased belt life and a refined aesthetic under the hood. Weighing only 0.20 lbs, it significantly reduces rotational mass compared to the stock component. This easy-to-install part not only prevents future failure but also contributes to noticeable improvements in throttle response, horsepower, and torque. It comes with the pulley and a flange nut, backed by Perrin's Standard 5-Year Limited Warranty.
