Overview

The Perrin Lightened Crank Pulley is a precision-engineered upgrade designed to reduce rotational mass on a broad range of Subaru models, including the WRX, WRX STI, Legacy, Forester, Forester XT, Impreza, and Outback. By replacing the heavier OEM crank pulley with this lightweight alternative, Subaru enthusiasts can achieve quicker throttle response and faster engine revving, resulting in a more engaging and responsive driving experience. This pulley is ideal for drivers seeking improved performance without the need for complex modifications or tuning.

Crafted from durable 6061T6 aluminum and finished with a hard anodized black coating, the pulley offers excellent corrosion resistance and long-lasting reliability. Perrin Performance’s focus on quality and fitment ensures this pulley is a direct replacement for most Subaru EJ engines, compatible with OEM belts and pulleys. The design philosophy centers on delivering tangible performance gains through weight reduction while maintaining OEM-level durability and ease of installation.

For Subaru owners, this lightened crank pulley translates to a noticeable improvement in engine feel and acceleration responsiveness both on the street and track. The reduction of 3.7 pounds compared to the stock pulley decreases parasitic drag on the crankshaft, freeing up horsepower and enhancing throttle control. This upgrade complements other performance modifications and is a practical step toward maximizing the potential of your Subaru’s EJ engine platform.
