ACT T3RS-G21 – Mod-Twin 10.5 XX Sprung Race
ACT Mod-Twin 10.5 Extreme Sprung Race Clutch Kit
T3RS-G21 Mod-Twin 10.5 XX Sprung Race Kit performs aggressive launches and smoother shifting in high-powered machines by combining twice the ceramic friction surfaces with an ultra-durable sprung Mono-Drive hub assembly in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process to provide a consistent pedal feel requiring moderate effort. Puck-style Friction Plates with high quality ceramic friction materials deliver high friction coefficient, superior heat capacity, and long clutch life. These Friction Plates uniformly transfer torque to a Mono-Drive sprung hub assembly, which extends input shaft life and reduces driveline shock from torsional vibration. This 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, alignment tool and pilot bearing (where applicable). Mod-Twin clutches are fully rebuildable, and replacement discs may be ordered separately.
- “Excellence in Performance”, backed by the best one-year warranty in the industry!
