The ACT SB9-XTR4 is a high-performance clutch kit designed specifically for the most demanding drivers. With its Xtreme pressure plate, this kit delivers exceptional clamp load, reducing deflection and extending clutch life. Crafted with precision, the diaphragm undergoes a rigorous four-stage heat-treating process, ensuring top-notch performance even under extreme conditions.

One of the standout features of the SB9-XTR4 is its lightweight, rigid design. This allows for quicker shifts and a smoother driving experience. Many customers have noted that the engagement, while harsher than standard options, facilitates faster gear changes, making it ideal for those who thrive on the racetrack. One user shared, "I installed the ACT SB9-XTR4 on my WRX, and the difference was night and day. Shifting feels so much quicker!"

The 4-pad rigid race discs are constructed from high-quality ceramic friction materials, enhancing durability and performance. The chrome-moly hub is also heat-treated, adding to its strength. While the engagement may be aggressive, the benefits in speed and reliability make it worth it for serious racers. As another customer put it, "The SB9-XTR4 has transformed my driving experience. I feel more connected to my car during every shift."
