Description: The NS4-HDR4 kit features ACT's popular Heavy Duty pressure plate. 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 4-pad rigid race disc, made with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. This lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. The 4-pad rigid race disc provides aggressive engagement and increased gear rattle, making it well-suited for smaller engines.

Features:

  • 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, 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.

Wears out more quickly than standard versions

While my puppy loved this bone and it was a good starter toy, it didn't last long. Our lab puppy loves to chew - especially when we stuffed the ends on this bone. After about 1.5 months of moderate use, she ended up chewing off and swallowing a small chunk of this bone, which she thankfully passed without issue. The material of this bone is intentionally softer than other kong toys, so it breaks down easier, and you will need to inspect it for wear more frequently. We have since upgraded to the large super chewer version for her, and she still loves it.
