ACT HD/Race Sprung 4 Pad Kit Mazda RX-7 1983-1992 - ZX2-HDG4

ACT ZX2-HDG4 Heavy Duty/Race Sprung 4 Pad Kit

The ACT ZX2-HDG4 is an exceptional choice for performance enthusiasts looking to upgrade their clutch system. This kit features ACT's renowned Heavy Duty pressure plate, designed with an exclusive diaphragm that enhances clamp load, minimizes deflection, and maximizes the lifespan of your clutch. Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring top-notch performance that stands the test of time.

One of the standout features of the ZX2-HDG4 is its precision-engineered cover stampings, which contribute to rigidity and consistent performance. The kit includes a 4-pad spring-centered race disc that is specifically crafted to dampen torsional vibrations, resulting in quieter operation and increased durability, even under the most demanding conditions. Customers have noted that while the engagement can be harsher, the faster shifting makes it a worthwhile trade-off for spirited driving.

Feedback from users highlights the balance of light to moderate pedal effort with aggressive engagement, making it suitable for both high horsepower street applications and racing scenarios. The moderate friction life is extended thanks to ACT's innovative diaphragm design, which is a significant advantage for those pushing their vehicles to the limit.
