Product Details

The ACT T1S-B05 Mod-Twin Kit is a high-performance twin-disc clutch conversion system engineered by Advanced Clutch Technology (ACT) for demanding performance and motorsport applications. Designed for vehicles requiring significantly elevated torque capacity beyond what a single-disc clutch can reliably handle, the Mod-Twin system provides a dramatic increase in clamping force and power transfer capability while remaining streetable for daily-driven performance vehicles.

Key Features:

  • Twin-Disc Design: Dual friction disc configuration dramatically increases torque capacity over single-disc setups
  • ACT Performance Pressure Plate: Precision-engineered for consistent, high-clamp force engagement
  • Modular Construction: The Mod-Twin platform allows for flexible disc material pairing to suit street, track, or competition use
  • Enhanced Heat Dissipation: Twin-disc layout improves thermal management under sustained high-load conditions
  • Reduced Rotational Inertia: Smaller diameter discs result in faster rev response and quicker shifts compared to large single-disc alternatives
  • ACT Quality Manufacturing: Built to strict tolerances using premium materials for long service life

The ACT Mod-Twin system is ideal for high-horsepower builds where clutch slippage, heat fade, or disc wear are concerns. Whether building a track-day car or a high-output street machine, the T1S-B05 delivers the reliability and performance ACT is known for.
