The ACT T1SS-N06 Mod-Twin 225 HD Sprung Street Kit is designed for high-powered AWD street cars like the Nissan Skyline GT-R (R32). It combines twice the organic friction surfaces of a single-disc clutch with an ultra-durable, spring-centered Mono-Drive hub in a fully modular design, delivering uncompromised pedal feel, durability, and engagement quality alongside very high torque capacity. Each diaphragm spring goes through 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, uniformly transferring torque to the sprung Mono-Drive hub assembly, which extends input shaft life and reduces driveline shock from torsional vibration.

FAQ
What makes the Mod-Twin 225 different from a single-disc clutch kit?
It combines two organic friction discs instead of one, roughly doubling the total friction surface, while using a sprung Mono-Drive hub for uncompromised pedal feel and much higher torque capacity than a single-disc setup.
What is included in the T1SS-N06 kit?
The kit includes a CNC-machined and 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 where needed.
Can the Mod-Twin clutch be rebuilt?
Yes, Mod-Twin clutches are fully rebuildable and most components can be ordered separately.
What Skyline years does the T1SS-N06 fit?
It fits the R32-chassis Nissan Skyline GT-R from 1989-1992. A separate ACT Mod-Twin kit covers later 1993-1998 R32/R33 Skyline GT-R applications.
