ACT Heavy Duty HD/Race Sprung 4 Pad Clutch Kit for 1990-1993 Mazda Miata – Part Number actZM1-HDG4

The ACT 1991 Mazda Miata HD/Race Sprung 4 Pad Clutch Kit offers high-performance and durability for street and race applications. Featuring ACT's most popular Heavy Duty pressure plate, this kit utilizes an exclusive diaphragm design that increases clamp load, reduces deflection, and maximizes clutch lifespan. All diaphragms undergo a four-stage heat-treating process, ensuring consistent and reliable performance under demanding conditions. The precision cover stampings enhance rigidity and balance, contributing to smoother operation and improved engagement. The 4-pad spring-centered race disc is engineered to properly damp torsional vibrations, providing quieter operation and resisting failure even under high-stress situations. ACT's spring retainers incorporate wraparound spring windows and thicker stampings, which support spring load, reduce stress concentrations, and enhance overall strength and reliability. The aggressive engagement of the 4-pad disc results in harsher engagement but allows for faster shifting, making it ideal for smaller engines and high-performance setups. Designed to withstand high heat and stress, the kit includes select ceramic friction materials for maximum performance and longevity. Carefully engineered, precisely assembled, and dynamically balanced, this clutch kit ensures smooth high-RPM operation and high torque capacity, making it suitable for high horsepower street or race use. Backed by ACT's industry-leading one-year warranty, this clutch kit delivers excellence in performance and reliability for your Mazda Miata.
