The PERRIN Lightweight Crank Pulley (PSP-ENG-100RD) is designed for Subaru EJ-series engines to reduce rotating mass and free up usable power. By replacing the heavy factory crank pulley with a precision-machined aluminum unit, throttle response improves immediately and the engine revs more freely—something you can feel with every blip of the throttle.
Finished in a bold red anodized coating, this pulley delivers both performance gains and a clean visual upgrade to your engine bay.
