Advanced Clutch Mod-Twin 10.5 XT Sprung Street T2SS-G12 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. Features: Soft, progressive engagement, light pedal effort, smooth shifting with OE to mild 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 Street or Street/Strip 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: Organic Input Spline Quantity: 26 Input Shaft Diameter: 1.125 in Alignment Tool Included: Yes Disc Type Sprung Solid: Sprung Pressure Plate Bolts Included: No Clutch Slave Cylinder Included: No Flywheel Bolts Included: Yes Pilot Bearing Included: Yes Product Weight (lbs.): 42.4 SFI: 1.2 Torque Capacity (ft/lbs.): 1169 Torque Capacity Over OE: 0.68 References Installation Instructions Applications 2009 Cadillac CTS V 2010 Cadillac CTS V 2011 Cadillac CTS V 2012 Cadillac CTS V 2013 Cadillac CTS V 2014 Cadillac CTS V 2015 Cadillac CTS V 2012 Chevrolet Camaro ZL1 2013 Chevrolet Camaro ZL1 2014 Chevrolet Camaro ZL1 2015 Chevrolet Camaro ZL1
