The T2SS-S01 Mod-Twin 225 XT Sprung Street Kit is engineered for high-powered AWD street cars, combining twice the organic friction surface area with an ultra-durable spring-center Mono-Drive hub in a fully modular design. Each diaphragm spring goes through ACT's exclusive four-stage heat-treating process for a consistent, light pedal feel, while steel-backed friction plates deliver a stable friction coefficient, strong heat capacity, and long clutch life. The Mono-Drive sprung hub assembly extends input shaft life and reduces driveline shock from torsional vibration. The kit includes a CNC-machined, dynamically balanced flywheel, pressure plate cover, diaphragm spring, 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.
