Advanced Clutch Mod-Twin 10.5 XT Rigid Race T2R-F12 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. Features: Predictable, aggressive engagement, light 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 Drag, Road or Rally Racing Applying tactical engineering to the Mod-Twin, ACT presents unique solutions to common tradeoffs found on twin disc clutches, resulting in an ultra-durable, customer serviceable, long-lasting clutch with very high torque capacity. All are 100% clamp load tested, balanced and SFI certified Specifications: Clutch Master Cylinder Included: No Grease Included: Yes Grade Type: Performance Flywheel Included: Yes Pilot Bushing Included: No Pressure Plate Type: Xtreme Release Bearing Included: No Clutch Disc Diameter: 10.5 in Clutch Disc Diameter: 267 mm Disc Material: Ceramic Input Spline Quantity: 23 Input Shaft Diameter: 1 in Alignment Tool Included: Yes Disc Type Sprung Solid: Solid Pressure Plate Bolts Included: No Clutch Slave Cylinder Included: No Flywheel Bolts Included: Yes Pilot Bearing Included: Yes Product Weight (lbs.): 44.5 SFI: 1.2 Torque Capacity (ft/lbs.): 1263 Torque Capacity Over OE: 1.08 References Installation Instructions Applications 2018 Ford Mustang GT 2018 Ford Mustang GT Premium 2018 Ford Mustang V8 2019 Ford Mustang Bullitt 2019 Ford Mustang GT 2019 Ford Mustang GT Premium 2019 Ford Mustang GT V8 2020 Ford Mustang Bullitt 2020 Ford Mustang GT 2020 Ford Mustang GT Premium 2020 Ford Mustang GT V8 2021 Ford Mustang GT 2021 Ford Mustang GT Premium 2021 Ford Mustang GT V8 2021 Ford Mustang Mach 1 2022 Ford Mustang GT 2022 Ford Mustang GT Premium 2022 Ford Mustang GT V8 2022 Ford Mustang Mach 1 2023 Ford Mustang GT 2023 Ford Mustang GT Premium 2023 Ford Mustang GT V8 2023 Ford Mustang Mach 1
