Introducing the ACT Mod-Twin 225 HD Rigid Street T1S-S01 clutch kit, designed for performance enthusiasts who demand both reliability and responsiveness from their vehicles. This innovative clutch system combines a soft pedal feel with quick engagement, making it ideal for high-powered all-wheel drives. The T1S-S01 features a unique rigid Mono-Drive hub, ensuring that shifting is not only smooth but also incredibly precise.

One of the standout features of the T1S-S01 is its dual organic friction surfaces, which provide excellent torque transfer and longevity. Customers have noted how the clutch engages positively, allowing for a seamless driving experience. "I've been using the T1S-S01 for a few months now, and I can really feel the difference in responsiveness," shared a satisfied user. "The pedal feel is just right, not too stiff, and the shifts are quick. It’s a game changer for my Subaru!"

Constructed with a forged aluminum cover and premium friction materials, this clutch kit is built to withstand the rigors of performance driving. The diaphragm spring undergoes a four-stage heat treatment process, enhancing its durability and heat resistance. Additionally, the steel-backed friction plates are designed to maintain a stable friction coefficient, ensuring consistent performance under pressure.

The T1S-S01 kit comes complete with everything you need for installation, including a CNC-machined flywheel, pressure plate cover, diaphragm spring, and more. Each component is engineered for easy serviceability, allowing you to keep your clutch in top shape for years to come. "I appreciate that I can rebuild this clutch myself," noted another customer.
