PERRIN 22-25 Subaru WRX/BRZ & Toyota GR86 / 20-25 FXT/OBXT Lightweight Crank Pulley - Black

This product is a PERRIN lightweight crank pulley, finished in black. It's designed to replace the factory crank pulley on specific Subaru and Toyota models. The main goal of this part is to reduce the rotational mass at the end of your engine's crankshaft.

By using a lighter-weight pulley, you're lessening the inertia the engine has to overcome to spin up and slow down. This can lead to a more responsive feel from the engine, especially noticeable during acceleration and deceleration. The pulley is made from aluminum and anodized black for a clean look. It's a direct replacement for the stock unit, meaning it bolts on without needing modifications to your existing setup.

When installing this, remember that while it reduces rotational mass, it doesn't add horsepower directly. The benefit comes from how quickly the engine can change its speed. Make sure to follow the manufacturer's installation instructions carefully for proper fitment and function.
