Description: The NS4-HDR6 kit features ACT's popular Heavy Duty pressure plate paired with a 6-pad rigid race disc. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. These pressure plates undergo a four-stage heat-treating process for unparalleled performance and feature precision cover stampings for rigidity and consistency.

Paired with the Heavy Duty pressure plate is ACT's 6-pad rigid race disc, made with high-quality ceramic friction materials and a chrome-moly hub heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth service, although engagement may be harsher. This setup is recommended for larger clutch sizes to absorb more heat, making it suitable for race use.

Features:

• Feel: Light to moderate pedal effort, aggressive engagement, increased gear rattle
• Life: Moderate friction life, extended by ACT's exclusive diaphragm design, although rigid design may increase spline wear
• Quality: Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance
• Recommended Use: Recommended for race use only
• ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

Vehicle Fitment: Compatible with 1989-1990 Nissan 180SX Type I and Type II [JDM] models equipped with a 1.8L I4 FI engine.
