Tilton’s OT-140 5.5″ heavy duty metallic clutches offer the low moment-of-inertia, high torque capacity and reliability necessary for the most demanding racing applications. These features have made metallic clutches the most common clutch type used in road racing and circle track racing. The included high ratio pressure plate features short release travel for quick engagement and shifting as well as a flat clamp load curve for longer wear range. Metallic clutches are not recommended for street use.
5.5″ OT-140 heavy duty metallic racing clutch applications:
Design: Open, one-piece clutch cover design provides lower operating temperature, high strength and minimal deflection for quick shifting.
Engineering: Chrome vanadium diaphragm springs and an engineered pressure plate geometry provide a high clamp load-to-wear ratio, low release load and quick shifting.
Materials: High-strength steel is used in both the pressure plates and the floater plates.
Toughness: .104″-thick friction disc withstands elevated temperatures while providing low inertia and excellent wear resistance.
