ACT Xtreme Clutch Kit 2004-2021 STI

ACT makes some of the best aftermarket clutches in the business, and we use them in our own Mach V project cars.

An ACT clutch package delivers significantly better power handling AND durability over the stock clutch, with minimal driveability trade-offs (at least in the full face models). All ACT clutches use new, not rebuilt, parts.

Here at Mach V Motorsports, we have used ACT products for years and have nothing but good experiences with them.

Each kit includes a throwout bearing, pilot bearing, and an alignment tool — everything you need for installation. Xtreme Duty pressure plate, full-face clutch disc. Rated at 566 ft-lbs of torque.

Tech Tip : Torque Clutch cover bolts to 11.8 ft lbs in a crisscross method

Fits 2004+ STI, including 2015-2021.
