Description
The ACT T2SS-B01 Mod-Twin 225 XT Sprung Street Clutch Kit is engineered for high-powered AWD street cars requiring exceptional torque capacity, smooth street manners, durability, and consistent engagement. This Extreme-duty twin-disc clutch combines twice the organic friction surfaces with an ultra-durable spring-centered Mono-Drive hub in a completely modular design.
The sprung Mono-Drive hub helps reduce driveline shock caused by torsional vibration while extending input shaft life. Each diaphragm spring undergoes an exclusive four-stage heat-treating process to provide consistent, light pedal effort and dependable performance. Steel-backed friction plates with high-quality organic friction materials provide a stable friction coefficient, good heat capacity, and long clutch life.
The friction plates uniformly transfer torque to the Mono-Drive sprung hub assembly. The result is a high-capacity clutch system designed to deliver excellent pedal feel, engagement quality, durability, and performance for demanding street and street/strip applications.
The ACT Mod-Twin 225 XT Sprung Street 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 if needed.
Mod-Twin clutches are fully rebuildable, and most individual components can be ordered separately, providing long-term serviceability and making this clutch suitable for high-powered applications where rebuildability and component replacement are important.
