Mod-Twin Kit

T3SS-G13 Mod-Twin 10.5 XX 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, release bearing, alignment tool and pilot bearing (where applicable). Mod-Twin clutches are fully rebuildable, and replacement discs may be ordered separately.
