Overview
The Perrin Lightened Crank Pulley is a precision-engineered upgrade designed to reduce rotational mass on a wide range of Subaru models including the WRX, Subaru WRX STI, Legacy, Forester, Outback, and Impreza. By replacing the heavier OEM crank pulley with this lightweight alternative, Subaru enthusiasts gain quicker throttle response and faster engine revving, resulting in a more engaging and responsive driving experience. This pulley is ideal for drivers seeking a straightforward performance enhancement without the need for complex modifications or tuning.
Crafted from CNC-machined 6061T6 aluminum and finished with a durable hard anodized red coating, the pulley combines strength, corrosion resistance, and lightweight design. Perrin Performance’s engineering approach focuses on maintaining OEM-level reliability while delivering tangible performance benefits. The pulley’s direct bolt-on fitment ensures compatibility with most Subaru EJ engines and works seamlessly with OEM belts and pulleys, preserving factory reliability and ease of installation.
Reducing the crank pulley’s weight by 3.7 lbs compared to stock significantly decreases rotational inertia, allowing the engine to accelerate more freely. This translates to improved throttle response and quicker engine spool-up, which benefits both spirited street driving and track use. For Subaru owners, this upgrade enhances the driving experience by making the engine feel more lively and responsive without sacrificing durability or requiring additional tuning.
