IAG Spec Exedy Triple Disc Clutch Kit (24 Spline) 2004-2021 STI

The IAG Spec Exedy Triple Disc Clutch was developed in a collaborative partnership with Exedy, known as the undisputed world leader of performance sports and racing clutches. This specially designed clutch was engineered for high-powered 2004-2021 Subaru STIs with OEM 6 speed (24 spline input shaft) manual transmissions. While this clutch is streetable, it has the ability to handle an impressive 923 ft/lbs of torque, which makes it ideal for track days, drag racing, or just straight-up aggressive driving. This torque rating is over 150 ft/lbs higher than the standard FM023SB Exedy triple disc clutch. The IAG Spec Exedy Triple Disc Clutch is the perfect balance of street functionality, combined with the capacity to stand up to high-power modified engines.

The stock Subaru clutch is equipped with a single disc, which is sufficient to handle the lower power output of an unmodified engine. Engines with significant power upgrades require a more powerful clutch that can take on considerably higher torque and heat levels in comparison to the OEM version. The three-disc design in the IAG Spec Exedy Triple Disc Clutch effectively triples the overall grip and increases power transfer efficiency without slipping. With three discs to share in the torque load and heat distribution, excessive heat issues that can lead to clutch fade and reduced performance are eliminated. Please be aware that some level of “rattling” noise is expected when the clutch is depressed or the vehicle is in neutral.
