Description: The NS4-HDSS kit features ACT's popular Heavy Duty pressure plate paired with their most popular street 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 superior performance. Precision cover stampings provide rigidity and consistency.

Paired with the Heavy Duty pressure plate is ACT's Performance Street disc, featuring premium organic materials with a high copper content for improved heat transfer and a steel-backed lining for greater burst strength and durability. These discs have reduced marcel for faster shift action to complement ACT pressure plates, offering increased strength and reliability.

Features:

  • Feel: Light to moderate pedal effort, smooth positive engagement, OE to mild gear rattle
  • Life: Longer friction life, extended by ACT's exclusive diaphragm design
  • Quality: Carefully engineered, precisely assembled, accurately balanced, with premium organic friction materials for heat tolerance and reduced fade
  • Recommended Use: Recommended for street and race use
  • 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.
