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. Rated to 660 lb/ft of torque.

About this Heavy Duty six-puck kit, ACT says: "A low to moderate pedal feel; aggressive engagement with stock to low to moderate gear rattle. Monoloc provides uniform loading on the bearing and pressure plate to assure proper alignment, regardless of driver influence or vehicle modifications."

Tech Tip : Torque Clutch cover bolts to 26 ft lbs in a crisscross method.

Fits all 2004-2021 Subaru WRX STI.
