Product Fitment:
2022-2025 Subaru BRZ
2022-2025 Toyota GR86
Upgrade your BRZ or GR86 with a lightweight, durable alternator pulley from PERRIN. This performance-focused upgrade reduces rotational mass, sharpens throttle response, and eliminates common failure points—all with precision craftsmanship and stylish anodized finishes.
Features:
-
Reduces Rotational Mass
Weighing in at only 0.20 lbs—significantly lighter than the OEM clutch-style pulley—this upgrade sharpens throttle response and may boost horsepower and torque. -
Eliminates Common Failure Point
OEM clutch-type alternator pulleys are known to fail over time, causing belt issues, knocking noises, and charging problems. The PERRIN pulley is engineered to remove this weak link for improved reliability. -
Precision-Machined Design
Crafted from robust 6061-T6 billet aluminum, available in anodized black, blue, or red. Laser-etched grooves ensure a secure, OEM-like belt engagement and lasting belt life. -
Stylish Finish Options
Anodized color choices let you match engine bay aesthetics: black, blue, or red. -
Includes Necessary Hardware
Comes with a flange nut and installation instructions, backed by PERRIN’s 5-year warranty. -
Quick & Simple Installation
Typically takes around 30 minutes for a DIY install.
