ACT T2SS-N04 Mod-Twin 225 XT Sprung Street Twin Disc Clutch Kit

The ACT T2SS-N04 Mod-Twin 225 XT Sprung Street Clutch Kit is engineered for high-powered AWD street cars demanding maximum torque capacity without sacrificing daily drivability. By combining twice the organic friction surfaces with an ultra-durable sprung-center Mono-Drive hub in a fully modular design, this twin disc clutch kit delivers exceptional torque holding, smooth engagement, and a street-friendly pedal feel.

Each diaphragm spring undergoes ACT's exclusive four-stage heat treating process, ensuring a consistent, light pedal effort over the life of the clutch. Steel-backed Friction Plates with premium organic friction materials provide a stable friction coefficient, excellent heat capacity, and long service life. Torque is uniformly transferred through the Mono-Drive sprung hub assembly, which helps reduce driveline shock from torsional vibration and extends input shaft life.

• CNC-machined and dynamically balanced flywheel
• Pressure plate cover and diaphragm spring
• Puck-style ceramic and organic friction plates
• Sprung Mono-Drive hub assembly
• Floater plate
