ACT MS1-XTR6 Clutch Kit

The ACT MS1-XTR6 Clutch Kit is engineered for the performance driver who demands reliability and responsiveness in high-stress situations. This kit features an Xtreme pressure plate designed with an exclusive diaphragm configuration that increases clamp load while minimizing deflection, ultimately enhancing clutch longevity.

Construction and Design

The pressure plate undergoes a rigorous four-stage heat-treating process, ensuring superior performance under extreme conditions. Precision cover stampings provide the necessary rigidity and consistency, critical for maintaining performance in competitive environments. The 6-pad rigid race discs are crafted from high-quality ceramic friction materials, which are designed to withstand high temperatures and provide consistent engagement.

Performance Characteristics

• Weight: 15.2 lbs
• Torque Capacity: 565 ft/lbs, with a 1.3x increase over OEM specifications
• Disc Diameter: 9.4 in (240 mm)
• Input Spline Quantity: 23
• Input Shaft Diameter: 1 in

The lightweight and rigid design of the MS1-XTR6 allows for quicker shifts, making it ideal for racing applications. However, note that the engagement can be harsher, which may lead to increased gear rattle. This clutch kit is recommended for larger clutch sizes, as it can absorb more heat effectively.
