Introducing the ACT T1R-S01 Mod-Twin 225 HD Rigid Race Kit, designed specifically for performance enthusiasts who demand excellence in their clutch systems. This state-of-the-art kit is engineered to handle the aggressive launches and rapid shifts characteristic of high-powered AWD vehicles. With its innovative design, the T1R-S01 combines double the ceramic friction surfaces with a robust Mono-Drive hub, ensuring that you get the most out of your ride.
One of the standout features of this clutch kit is its light pedal feel, thanks to a unique four-stage heat treating process applied to each diaphragm spring. This means you can enjoy a more comfortable driving experience without sacrificing performance. The puck-style friction plates are crafted from high-quality ceramic materials, providing a high friction coefficient, excellent heat capacity, and an extended clutch life—perfect for those who push their vehicles to the limit.
Customers have praised the T1R-S01 for its predictable aggressive engagement and quick shifting capabilities. One user noted, "The installation was straightforward, and the performance boost was immediately noticeable. Shifts are crisp, and I feel in complete control." Another added, "After switching to the T1R-S01, my car feels more responsive, especially during launches."
The kit comes complete with everything you need for a successful installation: a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, puck-style ceramic friction plates, and more. Plus, it's fully rebuildable, allowing you to replace components as needed without having to invest in a whole new system.
