Description: The ZM4-HDG4 kit by ACT comprises their most popular Heavy Duty pressure plate matched with a 4-pad spring-centered race disc. ACT Heavy Duty pressure plates employ an exclusive diaphragm design to augment clamp load, diminish deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for exceptional performance. Precision cover stampings ensure rigidity and consistency.

The 4-pad spring-centered race disc features a spring-center to appropriately damp torsional vibrations for quieter operation and resist failure even under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. Engagement with the 4-pad spring-centered race disc is harsher, but shifting is faster. It's well-suited for smaller disc sizes in smaller engines.

Key Characteristics:

  • 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, where quick, aggressive shifts are necessary.

ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability.

Vehicle Fitment: Compatible with various Mazda MX-5 Miata models from 2006 to 2015, including Grand Touring, Sport, Touring, GT, Special Edition, Club, and GS. All models equipped with the 2.0 L4 GAS FI 2000cc engine.

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

Great quality and built to last. My dog really enjoys playing with it and stays entertained for quite a while. The material is strong yet safe, and the included drawstring bag is a convenient extra for easy storage. Is colorful and my become my puppy’s favorite.

If you love your dog…don’t buy this.
Color: Orange
We have a nonaggressive English cocker. She opened the ball every time she played with it. And yes, we are closing it as hard as we can. I do not recommend this toy for any dog! This is a dangerous toy for a dog that is not supervised.
