The ACT TC4-HDR6 is a top-notch Heavy Duty Clutch Kit designed for performance enthusiasts looking to enhance their driving experience. This kit features ACT's renowned Heavy Duty pressure plate, which utilizes an exclusive diaphragm design. This unique construction increases clamp load, minimizes deflection, and ultimately maximizes the lifespan of your clutch.
Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring unparalleled performance under pressure. The precision cover stampings of the pressure plates provide additional rigidity and consistency that you can rely on during intense driving conditions.
One of the standout features of the TC4-HDR6 is its 6-pad rigid race disc. Constructed from high-quality ceramic friction materials, this disc is built to withstand high temperatures and heavy use. The chrome-moly hub is heat-treated for added strength and durability, making it a reliable choice for those who demand performance.
Customers have noted that while the engagement can be harsher with the 6-pad design, the benefit is significantly faster shifting, which is crucial for racing applications. One user mentioned, "The TC4-HDR6 transformed my driving; shifts are lightning-fast and the clutch feels solid!"
This clutch kit is specifically compatible with the Toyota Celica (1989-1993), ensuring a perfect fit for your vehicle.
