The stage two clutch range is designed for road and track-going vehicles that require a higher torque capacity, temperature tolerance, and faster engagement. Clutch engagement is more aggressive than stage 1, so it is not recommended for daily-driven vehicles.

These kits feature a high-quality cover with increased clamping force compared with standard, between 20-40% depending on the demands of the individual vehicle. They use a ceramic friction disc with multiple segments to provide a similar working temperature range as 1B discs, but with slightly smoother engagement.

This kit is used more rarely, but it is available for situations such as low-speed trials, tracks where the operator encounters temperatures that are too high for organic, and consequently need a higher temperature clutch, but with better modulation than 1B. Usually, customers only purchase this option if they have previously used a 1A and found it insufficient due to the operators driving style or the particular demands of the vehicle.
