The ACT HC3-HDG4 clutch kit is designed for high-performance applications in 1989 Honda Civics and Honda CRXs. Featuring ACT's most popular Heavy Duty pressure plate, this kit provides increased clamp load, reduced deflection, and maximized clutch longevity. The exclusive diaphragm design undergoes a four-stage heat-treating process, ensuring unparalleled durability and consistent performance under demanding conditions. Precision cover stampings contribute to the rigidity and uniformity of the pressure plate, promoting smooth engagement and reliable operation. The kit includes a 4-pad spring-centered race disc that effectively dampens torsional vibrations, resulting in quieter operation and improved durability even in high-stress environments. ACT's spring retainers incorporate wraparound spring windows and thicker stampings, which support the springs better, reduce stress concentrations, and enhance overall strength and reliability. This combination delivers a harsher engagement for quicker shifts, making it ideal for smaller engines and applications requiring aggressive performance. The lightweight design requires light to moderate pedal effort, providing a responsive driving experience while producing some mild gear rattle typical of high-performance setups. Carefully engineered and precisely assembled, this clutch kit uses select ceramic friction materials capable of withstanding high heat, ensuring maximum performance and longevity. It is recommended for high-horsepower street or race use, offering a balance of aggressive engagement and durability. Each unit is 100% clamp load tested and dynamically computer-balanced to guarantee smooth high-RPM operation. Backed by ACT's industry-leading one-year warranty, the HC3-HDG4 kit is a reliable choice for enthusiasts seeking enhanced performance in their Honda Civic or CRX.

Note: Must be used with factory flywheel.
