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).
High Torque Capacity
Tilton’s 5.5″ carbon clutches can handle 250 lb-ft (340 Nm) of torque per plate with a high-ratio pressure plate, and 300 lb-ft (408 Nm) of torque per plate with an ultra-high-ratio pressure plate.
Decades of Experience
Tilton Engineering invented the carbon/carbon racing clutch and patented the drive system in the 1980s. It was the first carbon/carbon clutch ever to win a Formula One Grand Prix (Ayrton Senna’s Lotus-Honda at the 1980 US Grand Prix in Detroit). Since then, Tilton carbon/carbon clutches have been continually refined to be the best carbon clutches on the market. They have seen multiple victories in races worldwide, from the 24 Hours of Le Mans to the Baja 1000.
Capitalizing on experience gained over the past decades, Tilton carbon clutches have evolved to become second to none in quality. Each is built using the finest materials, the latest in manufacturing processes and is held to strict quality control standards. As part of their build process, 5.5″ OT-III carbon racing clutches are rigorously tested and documented before being delivered to the customer.
