2022+ Subaru BRZ & Toyota GR86
PSP-ENG-122BK / PSP-ENG-122BL / PSP-ENG-122RD
Overview:
The Perrin Alternator Pulley is a precision-engineered upgrade designed specifically for the 2022 and newer Subaru BRZ and Toyota GR86 models. This pulley replaces the OEM clutch-style alternator pulley, which is known to fail over time, causing issues such as knocking noises, battery charging problems, and premature belt wear. By eliminating this failure point, the Perrin Alternator Pulley enhances reliability while also reducing rotational mass for improved engine response.
Ideal for enthusiasts seeking a durable, lightweight component that also adds a clean, performance-oriented look to their engine bay, this pulley offers a straightforward installation and compatibility with both OEM and aftermarket belts. It’s a practical upgrade that supports better throttle response, horsepower, and torque without compromising daily drivability.
Key Features:
Engineered for performance and reliability, the Perrin Alternator Pulley offers the following benefits:
Construction & Design:
The Perrin Alternator Pulley is crafted from premium 6061 T6 billet aluminum, a material known for its excellent strength-to-weight ratio and resistance to corrosion. The pulley undergoes a meticulous CNC machining process to achieve precise dimensions and groove profiles that perfectly match OEM and aftermarket belts. Its anodized finish not only adds visual appeal but also provides a durable protective coating that resists wear and environmental damage.
Designed with both aesthetics and function in mind, the pulley’s lightweight construction reduces rotational inertia, allowing the engine to rev more freely and respond quicker to throttle inputs. The laser etching ensures consistent belt grip and longevity, contributing to overall drivetrain reliability.
Performance & Sound
By replacing the heavier OEM clutch-style alternator pulley with a lightweight, solid pulley, the Perrin Alternator Pulley reduces parasitic drag on the engine. This reduction in rotational mass translates to improved throttle response and a modest increase in horsepower and torque. Additionally, the removal of the failing clutch mechanism eliminates associated knocking noises, resulting in a smoother and quieter engine operation.
Installation & Fitment:
Installation of the Perrin Alternator Pulley is straightforward and designed to be a direct replacement for the OEM pulley on 2022 and newer Subaru BRZ and Toyota GR86 models. No modifications to the alternator or belt routing are required. The pulley comes with a flange nut for secure mounting, and detailed installation instructions are included to guide you through the process. This upgrade is suitable for enthusiasts of all skill levels looking to enhance reliability and performance.
What's Included:
Ideal For:
This alternator pulley is perfect for Subaru BRZ and Toyota GR86 owners who want to prevent common OEM pulley failures while gaining a lightweight, durable upgrade that improves engine responsiveness. It is especially suited for enthusiasts who have or plan to install other performance components such as the Perrin Crank Pulley, or those seeking a reliable, maintenance-free pulley solution for daily driving and spirited driving alike.
PERRIN Performance is an enthusiast-focused brand known for bolt-on performance and chassis upgrades for platforms like Subaru and other sport compacts. Their catalog spans intake and turbo support, drivetrain and shifter feel, and handling accessories—built for drivers who want tighter response and track-ready reliability without sacrificing daily drivability.

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
