2022-2026 Subaru BRZ
2022-2026 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.
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.
