The ACT T2R-S05 Mod-Twin 225 XT Sprung Race Kit delivers aggressive launches and smoother shifting in high-powered AWD Subarus, combining twice the ceramic friction surface of a single-disc clutch with an ultra-durable Mono-Drive sprung hub assembly in a fully modular design. Every diaphragm spring undergoes ACT's exclusive four-stage heat-treating process for a consistent, light pedal feel, and puck-style friction plates with high-quality ceramic material deliver a high friction coefficient, superior heat capacity, and long clutch life. The friction plates transfer torque uniformly to a Mono-Drive sprung hub assembly that extends input shaft life and reduces driveline shock from torsional vibration. The kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, ceramic friction plates, sprung Mono-Drive hub assembly, floater, patented Monoloc collar, release bearing, alignment tool, and pilot bearing if needed. This kit is intended for race use and is not recommended for street use.

FAQ
What is the torque capacity of the T2R-S05 kit?
1,120 ft-lb, using a twin 225mm ceramic puck-style disc setup on a sprung Mono-Drive hub.
Is this kit street legal or street friendly?
No, ACT recommends the XT Sprung Race configuration for race use only, not street use, due to its aggressive puck-style engagement.
Why does this kit use a sprung hub instead of rigid?
The sprung Mono-Drive hub assembly absorbs torsional driveline shock, reducing wear on the input shaft compared to a rigid hub, while the ceramic discs still deliver race-level torque capacity.
Can Mod-Twin clutch components be replaced individually?
Yes, Mod-Twin clutches are fully rebuildable and most components can be ordered separately.
