Tilton Engineering developed the first carbon racing clutch, and received a patent on it’s drive system, in the mid-80’s. It was the first carbon clutch ever to win a Formula One race (Ayrton Senna’s Lotus-Honda at the 1987 US Grand Prix in Detroit). Since then, Tilton OT-Series carbon clutches have been continually refined to be the best carbon clutches on the market. They have won numerous races worldwide, from the 24 Hours of Le Mans to the Baja 1000.
Utilising the experience Tilton has gained over the last 20-plus years, OT-Series carbon clutches have evolved to be 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, OT-Series carbon clutches are rigorously tested and documented before being delivered to the customer.
Tilton OT-Series carbon clutches offer a unique combination of a very low inertia, high torque capacity, high heat capacity and smooth engagement characteristics. Because of these features, they can be found used in endurance racing, road racing, off-road racing, drag racing and high-performance street applications. The carbon matrix plates (driven & floater) do not warp from heat, providing consistent gear changes and minimising heat-related clutch failures. The smooth engagement characteristics of the carbon plates provide good drivability and reduce “shock” to other driveline components. Through the use of additional pressure plates (shims) and periodic rebuilds, OT-Series carbon clutch offer long life. Each Tilton carbon clutch is dyno tested for torque capacity prior to shipment, marked with a unique serial number, entered into Tilton’s database and shipped with a complete built sheet. Additional pressure plates (shims), designed to compensate for carbon wear, enable customers to service the clutch themselves.
