The ACT XT/Race Rigid 4 Pad Clutch Kit is a high-performance clutch assembly designed for demanding driving conditions. Featuring an Xtreme pressure plate with an exclusive diaphragm design, this kit increases clamp load, reduces deflection, and maximizes clutch lifespan. The pressure plates undergo a four-stage heat-treating process to ensure durability and consistent performance, while precision cover stampings enhance rigidity. The 4-pad rigid race discs are constructed with high-quality ceramic friction materials, providing excellent grip and heat resistance. The chrome-moly hub is heat-treated for added strength, making this clutch kit ideal for intense racing applications and high-stress driving scenarios.

This clutch kit is suitable for vehicles requiring a robust, race-ready setup, typically used in motorsport or high-performance street driving. It is engineered for applications where maximum clamping force and durability are essential, often in modified or heavily tuned vehicles. Installation involves a direct replacement of the stock clutch components, ensuring a secure fit and reliable operation. The kit includes all necessary components for a complete upgrade, designed to withstand extreme conditions and deliver consistent power transfer. Suitable for use in vehicles with high horsepower or torque demands, this clutch kit enhances performance and longevity in competitive and spirited driving environments.

Overview

NS1-XTR4 kit features an Xtreme pressure plate for the most demanding driver. ACT Xtreme pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.

Features:

  • Moderate to heavy pedal effort, aggressive engagement, increased gear rattle
  • Moderate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear
  • Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance
  • Recommended for race use only
