Product Description: HD/Race Rigid 4 Pad Clutch Kit

The HD/Race Rigid 4 Pad Clutch Kit, designated as the ZM12-HDR4, embodies ACT's commitment to high-performance clutch solutions. Weighing 25.4 pounds, this kit delivers a remarkable torque capacity of 399 ft/lbs, surpassing OE standards by 87%. Crafted with a ceramic disc material, it features a clutch disc diameter of 8.8 inches (224mm) and an input shaft diameter of 0.9375 inches.

At its heart lies ACT's renowned Heavy Duty pressure plate, renowned for its exclusive diaphragm design. This design elevates clamp load, diminishes deflection, and maximizes clutch longevity. Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring unmatched performance. Precision cover stampings provide the necessary rigidity and consistency crucial for enduring performance under the most demanding conditions.

The clutch kit integrates ACT's 4-pad rigid race discs, engineered with premium ceramic friction materials. The chrome-moly hub is heat-treated for enhanced strength and durability. The lightweight, rigid design facilitates quicker shifts and ensures smooth, trouble-free operation. While engagement may be firmer with the 4-pad rigid race disc, shifting becomes noticeably quicker. This configuration is particularly well-suited for smaller disc sizes in smaller engines.

Key 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: Meticulously engineered, precisely assembled, accurately balanced, utilizing select ceramic friction materials for high heat tolerance and maximum performance.
  • Recommended Use: Designed for race use only, offering unparalleled performance in high-performance applications.
  • ACT Difference: Rigorously tested, ensuring 100% clamp load and dynamically computer balanced for smooth operation even at high RPMs.

Vehicle Fitment: This clutch kit is compatible with a range of Mazda MX-5 Miata models from 2016 to 2018, including various trim levels equipped with a 2.0 L4 GAS FI 1998cc engine. Compatible models include:

  • 2016-2018: Mazda MX-5 Miata Club, GS, GT, GX, Grand Touring, Sport
  • 2017-2018: Mazda MX-5 Miata RF Club, RF GS, RF GT, RF Grand Touring

Owners of these Mazda MX-5 Miata models seeking uncompromising performance can elevate their driving experience with the HD/Race Rigid 4 Pad Clutch Kit from ACT.

Shark dog approved
Size: Large, Color: Broccoli, Size: Large, Color: Broccoli
My new baby shark.... I mean puppy really enjoys chewing. I can't just give her a ton of pig ears or bully sticks all day, which she would definitely love, so I'm constantly looking for well made chew toys. I'd put this right up with Kong. Very durable and nice. I also love the different textures, she seems to also love it. She can gnaw at the top and chew on the stem. She wanted it as soon as I opened it - it does smell like bacon but I haven't taken a chomp at it to be able to write a complete review! My dog is about 23 lbs but I can see a 80 lb dog chew this, it's not small.

So cute
Size: Large, Color: Pumpkin
My French Bulldogs have really strong jaws and are aggressive chewers. These really are sturdy and last a good amount of time. They are a bit heavy and awkward for my dogs to hold onto but they do like them.

Cute toy and super tough!
Size: Small, Color: Lobster
My small dog is a serious chewer, and this lobster toy has been holding up great. Usually, he destroys toys within a day, but this one’s still going strong after a couple of weeks. The shape is perfect — easy for him to grab and chew, and the little claws keep him entertained. The filet mignon flavor must be good because he goes right for it every time. It’s sturdy without being too hard on his teeth, and it doesn’t leave any mess or pieces behind. If you’ve got a small but mighty chewer, this one’s definitely worth it. Cute design, lasts forever, and keeps my pup busy — total win. 🦞🐾
