Introducing the ACT ZM3-HDG6 Heavy Duty/Race Sprung 6 Pad Kit, designed for performance enthusiasts who demand reliability and power from their clutch system. This kit features ACT's renowned Heavy Duty pressure plate, which employs an exclusive diaphragm design that enhances clamp load while minimizing deflection. The result? A longer clutch life and improved performance under stress.
Each diaphragm undergoes a meticulous four-stage heat-treating process to ensure unparalleled durability. The precision cover stampings of the pressure plates provide the necessary rigidity and consistency that racers and street performers alike appreciate.
What sets the ZM3-HDG6 apart is its unique 6-pad, spring-centered race disc. This disc is engineered to dampen torsional vibrations effectively, making it reliable even in the most demanding conditions. The wraparound spring windows and thicker retainer stampings in the spring retainers enhance strength and reliability, reducing stress concentrations significantly.
While the engagement may feel a bit harsher, the trade-off is quicker shifting, making this kit an excellent choice for those who crave performance. It's particularly recommended for larger clutch sizes where heat absorption is critical.
"I installed the ZM3-HDG6 on my Mazda 3, and the difference is night and day! The engagement is aggressive, but I love how quickly I can shift now. Definitely worth the investment!" - Jamie T.
"I was impressed by the build quality of the pressure plate. It feels solid, and the performance has been fantastic so far. Highly recommend for anyone looking to upgrade!" - Alex R.
