ACT EXTREME DUTY RACE SPRUNG 4-PUCK CLUTCH KIT WITH FLYWHEEL - 2006-2021 WRX, 2022+ WRX
SKU: ACTSB11-XTG4
If you have a built block with a rotated turbo setup, then it may be time to upgrade to the ACT XT Race 4 Pad Clutch. This clutch holds up to 94% torque capacity over the factory clutch, so it is suitable for those who are aiming to make all the power. This clutch features ACT's Xtreme Pressure Plate which use an exclusive diaphragm design which increases clamp load, reduces deflection, and promotes better clutch life. Additionally, these diaphragms have gone through a four-stage heat treating process for long lasting performance.
Included with the pressure plate is the 4 Pad Sprung Race Disc. This disc has been made with premium ceramic friction materials with high copper content for efficient heat transfer. This disc also has heavy duty torsional dampening springs which have been designed to be much stronger than standard springs. Other additionals include heat-treated spring street drive plates designed for smaller disc sizes.
Also included is the XACT Streetlite Flywheel. This flywheel is a forged and CNC machined one-piece flywheel that is lighter than the factory flywheel. This means less rotational mass will be had at the crank which will allow for faster revs, and more horsepower and torque. This flywheel can be utilized for both street and race use.
These are the main ingredients of this clutch. Other components include a new release bearing, new pilot bearing, and finally an alignment tool to help with installation.
FITMENT NOTE: Due to change in the flywheel and clutch disc size, the following models MUST use this clutch and flywheel together as they WILL NOT be compatible with the OE or other stock sized replacement parts.
