Perrin Crank Pulley Black 15-18 WRX / 14-18 Forester XT / 13-14 Legacy / 13-21 BRZ / 12-14 Impreza | Lightweight 6061T6 Aluminum | Performance Crank Pulley
Overview
The Perrin Lightweight Crank Pulley is a precision-engineered upgrade designed to reduce rotational mass on Subaru FA engine platforms, including the WRX, Forester XT, Legacy, BRZ, and Impreza models. By replacing the heavier OEM crank pulley with this lightweight alternative, Subaru enthusiasts gain sharper throttle response and quicker engine revving characteristics without compromising reliability or requiring engine tuning. This pulley is ideal for drivers seeking a direct bolt-on performance enhancement that improves engine feel both on the street and track.
Manufactured from durable 6061T6 aluminum and finished with a hard anodized coating, the Perrin crank pulley combines strength with corrosion resistance to withstand demanding driving conditions. Its CNC-machined construction ensures exact OEM fitment and long-lasting durability. Perrin’s design philosophy focuses on delivering tangible performance benefits through weight reduction while maintaining OEM compatibility and ease of installation.
Reducing the crank pulley’s weight by over 3.7 pounds compared to the stock unit significantly decreases rotational inertia, allowing the engine to accelerate more freely. This translates into more immediate throttle response and a livelier driving experience that Subaru owners will appreciate. The pulley maintains compatibility with OEM belts and accessories, making it a practical upgrade for those looking to enhance their Subaru’s performance without extensive modifications.
