Benefits of using ACT Clutches:
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

Feel:
Predictable aggressive engagement, light pedal effort, smooth shifting, possible start-off judder with OE to mild transmission gear noise

Lifespan:
Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure this long-life twin disc performs and survives under the most demanding conditions

Quality:
Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances to provide top notch quality

Recommended Use:
Drag, Road, or Rally Racing

Difference between Sprung and Rigid:
When choosing between a sprung or solid hub clutch disc, consider the specific benefits of each:

• Sprung hub discs feature torsional dampeners that reduce driveline shock, extend spline life, and ensure quieter operation by minimizing torsional vibrations. For the quickest shifting, the four-pad option is ideal, while the six-pad version offers better heat capacity and smoother engagement.
• On the other hand, a solid hub discs are known for their enhanced durability due to stronger hub components. The four-pad design in a solid hub provides the fastest shifts, while the six-pad option balances improved heat capacity with smoother engagement.

More Info:
T1RS-S01 Mod-Twin 225 HD Sprung Race Kit performs aggressive launches and smoother shifting in high powered AWD’s by combining twice the ceramic friction surfaces with an ultra-durable Mono-Drive sprung hub assembly in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process providing a consistent light pedal feel. Puck-style Friction Plates with high quality ceramic friction materials deliver high friction coefficient, superior heat capacity, and long clutch life. These Friction Plates uniformly transfer torque to a 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, patented Monoloc Collar, release bearing, alignment tool and pilot bearing (if needed). Mod-Twin clutches are fully rebuildable and most components can be ordered separately.
