Description: The MR1-HDG4 kit by ACT features their renowned Heavy Duty pressure plate paired with a 4-pad spring-centered race disc, designed for high-performance street and race applications. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to bolster clamp load, minimize deflection, and extend clutch lifespan. Each diaphragm undergoes a meticulous four-stage heat-treating process for exceptional performance. Precision cover stampings on ACT pressure plates ensure rigidity and consistency. The 4-pad spring-centered race disc is engineered with a spring-center to effectively damp torsional vibrations and withstand harsh operating conditions. ACT's spring retainers provide additional support, reducing stress concentrations and enhancing reliability. While engagement may be more aggressive, the 4-pad spring-centered disc allows for quicker shifting, making it suitable for smaller engines with smaller disc sizes.

Features:

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

Junk!
Color: 3675 ALL Silver
Good luck getting the back plate back in once you change the battery! You get what you pay for so spend the extra money and buy a better watch not made in China.
