T2R-G11 Mod-Twin 10.5 XT 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 light pedal feel. 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, patented Monoloc Collar, release bearing, alignment tool and pilot bearing (where applicable). Mod-Twin clutches are fully rebuildable, and replacement discs may be ordered separately.

T2SS-G11 Mod-Twin 10.5 HD Sprung Street Kit is designed for high-powered street machines. It unites uncompromised pedal feel, durability, engagement quality with very high torque capacity by combining twice the organic 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 light pedal feel. Steel-backed Friction Plates with high quality organic friction materials deliver stable friction coefficient, good heat capacity and long clutch life. These Friction Plates uniformly transfer torque to the 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.

T1R-G09 twin disc kit offers twice the number of disc surfaces for better wear, heat capacity and long life compared to single disc kits. These kits use a proprietary Positive Lift Floater System design, which results in quiet operation with no floater rattle and no posts to wear. ACT twin disc kits endure an exclusive four-stage, heat treating process performed on all diaphragms. The ACT twin disc features the ability to adjust for disc wear and provides equal disengagement for discs. ACT’s 6-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and trouble-free service. All ACT twin disc kits include a CNC-machined and dynamically balanced flywheel to ensure trouble-free installation and operation.
