The ACT T2SS-F17 Mod-Twin 10.5 XT Sprung Street Clutch Kit is part of ACT's SFI-approved 10.5-inch Mod-Twin lineup released for the 2024-2026 Ford Mustang GT. The Mod-Twin design combines twice the organic friction surfaces with an ultra-durable sprung Mono-Drive hub assembly in a fully modular design, resulting in an ultra-durable, customer-serviceable, long-lasting clutch with extremely high torque capacity without the trade-offs typically associated with a twin-disc clutch. Each diaphragm spring endures ACT's exclusive four-stage heat-treating process, and steel-backed friction plates deliver stable friction coefficient, good heat capacity, and long clutch life. The kit is quietly capable of holding up to 986 ft-lb of torque for daily-driven street use.
