PERRIN 15-18 Subaru WRX / 13-20 BRZ / 14-18 FXT / 13-16 Crosstrek Lightened Crank Pulley - Blue

If you're looking to get a little more responsiveness out of your engine, a lightened crank pulley is a solid option. This Perrin pulley is designed to reduce rotational mass on the crankshaft, which means the engine can rev up and down more quickly. It's a popular modification for drivers who want to feel a more immediate connection to their engine's power, especially during spirited driving or track use.

This pulley is made from well-built aluminum and features a blue anodized finish for a clean look under the hood. Reducing the weight here helps the engine's internals spin up faster, making throttle inputs feel more direct. While it's a relatively simple part, it can make a noticeable difference in how the engine feels when you get on the gas or lift off.

When installing, remember that this part replaces the stock crank pulley. It's a good idea to check the manufacturer's installation instructions for any specific details or tool requirements.
