# ACT Mod-Twin 10.5 Maxx Xtreme Rigid Race Ceramic Clutch Kit; 26-Spline GM

T3R-G21 Mod-Twin 10.5 XX Rigid Race Kit tackles aggressive launches and rapid shifting of high-powered machines by combining twice the ceramic friction surfaces with a no-nonsense solid Mono-Drive hub 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 Chromoly hub, which is heat treated for strength and durability extending input shaft life with one continuous spline. The lightweight, rigid design allows for quicker shifts and trouble-free service. This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, rigid Mono-Drive hub, 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!
