PERRIN 93-14 Subaru Impreza (Incl. 02-14 WRX) / 04-21 STI Lightened Crank Pulley - Blue

This Perrin lightened crank pulley is made from a solid billet aluminum core, then precision-machined to reduce rotational mass. By shedding weight from the crankshaft, you'll notice an improved engine response, especially when you get on the throttle. It's a popular choice for Subaru owners looking to free up a little extra pep from their engine without going too deep into internal modifications.

The pulley is anodized blue for a clean look under the hood and features laser-etched Perrin branding. It's designed as a direct replacement for your factory crank pulley, making installation straightforward for those comfortable working around the engine bay. Reducing the inertia of the rotating assembly means the engine can spin up and down more freely, which can make the car feel a bit more eager to accelerate.
