The ACT GM9-HDG6 is engineered for those seeking robust performance in high-horsepower applications. This kit features ACT's renowned Heavy Duty pressure plate, designed to enhance clamp load while minimizing deflection, which contributes to extended clutch life. The diaphragm undergoes a rigorous four-stage heat-treating process, ensuring durability and reliability under extreme conditions.
The included 6-pad, spring-centered race disc is specifically designed to dampen torsional vibrations and withstand harsh racing conditions. This setup delivers faster shifting and a more aggressive engagement, making it ideal for larger clutch sizes that require enhanced heat absorption.
For optimal performance, the GM9-HDG6 must be paired with a flat flywheel or the ACT 600585 flywheel for LS2/LS3/LS7 applications. Installation requires standard tools and should be performed by a qualified technician to ensure proper fitment and function.
