ACT TL1-HDR4 Heavy Duty Clutch Kit

Introducing the ACT TL1-HDR4 Heavy Duty Clutch Kit, a top-notch solution designed for performance enthusiasts who demand reliability and power. This kit features ACT's renowned Heavy Duty pressure plate, engineered with an exclusive diaphragm design that enhances clamp load while minimizing deflection. This means not only an extended clutch life but also improved performance during those high-stakes moments on the track.

Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring unparalleled durability. The precision cover stampings offer rigidity and consistency, making this kit a favorite among racers. The 4-pad rigid race discs are crafted from high-quality ceramic friction materials, providing excellent heat tolerance and performance under pressure. The chrome-moly hub is heat-treated to enhance strength and longevity, ensuring that you can push your vehicle to its limits with confidence.

One of the standout features of the TL1-HDR4 is its lightweight, rigid design, which allows for quicker shifts and a smoother driving experience. While the engagement may feel harsher, it leads to faster shifting—a crucial advantage in competitive racing environments. This kit is particularly well-suited for smaller engines, making it a versatile choice for various setups.
