T3DS-F15 Mod-Twin 225 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 conditions—while 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.
Note: Predictable aggressive engagement, increased pedal effort, smooth shifting, possible start-off judder with OE to mild transmission gear noise; Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points 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; Recommended for 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
