ACT Mod-Twin Kits

T1DS-F15 Mod-Twin Track Sprung Race Kit Street/Strip delivers strong torque capacity with a softer launch, and smoother, more progressive engagement than our Xtreme six-puck disc kits. Designed for drag, road race, rally, and track-focused RWD applications, this kit combines twin ceramic friction surfaces with an ultra-durable sprung Mono-Drive hub assembly in a completely modular design. Each diaphragm spring undergoes ACT's exclusive four-stage heat-treating process for a light, consistent pedal feel and superior long-term performance. The new puck-style Friction Plates utilize a modified ceramic formulation that provides a lower initial bite for improved control during corner exits, downshifts, and traction-limited conditionswhile still delivering excellent heat capacity and clutch life. These friction plates uniformly transfer torque through the sprung Mono-Drive hub assembly, extending input shaft life and reducing driveline shock from torsional vibration. This complete 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 (if required). Mod-Twin clutches are fully rebuildable, with most components available individually. ACT Mod-Twin Heavy Duty Sprung Race Clutch Kit Street/Strip.
