The ACT T1S-M05 Mod-Twin 225 HD Sprung Street kit is designed for high-powered AWD street cars. It unites uncompromised pedal feel, durability, and engagement quality with very high torque capacity by combining twice the organic friction surfaces with an ultra-durable, spring-center Mono-Drive hub in a fully modular design. Each diaphragm spring endures ACT's exclusive four-stage heat-treating process for a consistent light pedal feel. Steel-backed friction plates with high quality organic friction material deliver a stable friction coefficient, good heat capacity, and long clutch life, transferring torque uniformly to the Mono-Drive sprung hub assembly, which extends input shaft life and reduces driveline shock. The kit includes a CNC-machined, dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, sprung Mono-Drive hub assembly, floater, patented Monoloc Collar, release bearing, alignment tool, and pilot bearing (if needed). Mod-Twin clutches are fully rebuildable and most components can be ordered separately.

Frequently Asked Questions
What does the ACT T1S-M05 Mod-Twin kit include?
It includes a CNC-machined, dynamically balanced flywheel, pressure plate, two puck-style ceramic-faced friction plates, sprung Mono-Drive hub assembly, floater, Monoloc Collar, release bearing, alignment tool, and pilot bearing if needed.
What is the Mono-Drive hub assembly for?
The sprung Mono-Drive hub transfers torque uniformly from the twin friction plates, extending input shaft life and reducing driveline shock from torsional vibration compared to a rigid-hub twin disc setup.
Can this kit be rebuilt?
Yes, Mod-Twin clutches are fully rebuildable and most components can be ordered separately from ACT.
Does California Proposition 65 apply to this product?
Yes. This product can expose users to chemicals including carbon black, glass wool fibers, silica, chromium, and nickel, which are known to the State of California to cause cancer or reproductive harm.
