Pulleys

Shop Subaru engine pulleys at IAG Performance, including ATI Super Damper crank pulleys, Gates idler and cam timing pulleys, and Kartboy, GReddy, and Perrin accessory pulleys for EJ20, EJ25, and FA20 engines. Upgraded pulleys help manage harmonics and improve reliability in higher-RPM, higher-boost builds, and a quality crank pulley in particular can reduce the risk of harmonic-related failures that plague stock pulleys under sustained high load.
