The ACT SB9-HDG6 Heavy Duty Clutch Kit is designed for performance enthusiasts who demand reliability and power in their vehicles. This kit showcases ACT's renowned Heavy Duty pressure plate, which features an exclusive diaphragm design that significantly boosts clamp load while minimizing deflection. What does this mean for you? Enhanced clutch longevity and performance under pressure, especially during spirited driving or racing scenarios.
One of the standout features of the SB9-HDG6 is the four-stage heat-treating process applied to all diaphragms, ensuring they can withstand extreme conditions without compromising performance. Customers have noted a marked improvement in clutch feel and responsiveness after installation, with one user stating, "The engagement is crisp, and I can feel the difference in power transfer!"
The kit includes a 6-pad spring-centered race disc, engineered to dampen torsional vibrations effectively. This design not only enhances reliability but also provides a more aggressive engagement, which many drivers appreciate when shifting at high RPMs. Another customer shared, "Shifting feels faster and more precise, which is exactly what I was looking for!"
Moreover, the SB9-HDG6 features ACT's patented Monoloc, a one-piece direct replacement for standard two-piece wedge collars. This innovative component ensures optimal alignment and uniform loading on the bearing and pressure plate, regardless of driving style or modifications made to the vehicle. With its hardened Chrome-moly steel construction, you can expect this clutch kit to deliver years of dependable service.
