Description: The NA1-HDR4 kit by ACT features their renowned Heavy Duty pressure plate matched with a 4-pad rigid race disc, tailored for race-specific applications. ACT Heavy Duty pressure plates employ an exclusive diaphragm design to enhance clamp load, minimize deflection, and prolong clutch life. Each diaphragm undergoes a meticulous four-stage heat-treating process for exceptional performance.

Complementing the Heavy Duty pressure plate is ACT's 4-pad rigid race disc, constructed with high-quality ceramic friction materials and a heat-treated chrome-moly hub for robustness. Its lightweight, rigid design facilitates swift shifts and ensures smooth operation, albeit with a harsher engagement for faster shifting. Ideal for smaller disc sizes in compact engines.

Attributes:

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

Vehicle Fitment: Compatible with various Nissan Stanza models equipped with 2.4L L4 engines from 1990 to 1992.
