ACT Mod-Twin 10.5 Heavy-Duty Race Clutch Kits

ACT Mod-Twin 10.5 Heavy-Duty Race clutch kits tackle 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 light and consistent 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. The kits include 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). In addition, these Mod-Twin clutches by ACT are also fully rebuildable, and replacement discs may be ordered separately. Product features: * Recommended for Drag, Road or Rally Racing * Predictable, aggressive engagement, lightest pedal effort, quick shifting, possible start-off judder with mild to moderate transmission gear noise * Forged aluminum cover, mono-drive hub, exclusive diaphragm, and premium friction materials ensure this long-life twin performs and survives under the most demanding conditions * Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances * 100 percent clamp load tested, balanced, and SFI certified Show Less
