Tilton’s 5.5″ OT-III carbon racing clutches offer a unique combination of extremely low inertia, high torque capacity, high heat capacity, and smooth engagement characteristics. The carbon matrix plates (driven and floater) do not warp from heat, providing consistent shifting and minimizing heat-related clutch failures.
The smooth engagement characteristics of the carbon plates provide excellent drivability and reduce shifting shock to other driveline components. Through the use of additional pressure plates (shims) and periodic rebuilds, 5.5″ OT-III carbon racing clutches offer a long-life option for the serious racer.
These features make Tilton’s 5.5″ carbon racing clutch ideal for the following applications:
- Road racing
- Endurance racing
- Short-course off-road
- Open-wheel/formula
Extremely Low Inertia
The moment of inertia for Tilton’s 5.5″ OT-III carbon racing clutches range from 14.6 lb-in2 (.0043 kg-m2) to 25.3 lb-in2 (.0074 kg-m2).
Lightweight
Tilton’s 5.5″ carbon clutches range in weight from 3.0 lbs (1.4 kg) to 5.2 lbs (2.3 kg).
