5.5" 3-Plate Metallic OT-III Racing Clutch Step Tiltons 5.5" 3-plate metallic OT-III heavy duty clutch offers 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" 3-plate metallic OT-III heavy duty clutch applications: - Road Racing - Circle Track - Open Wheel - Formula - Short Course Off Road 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. Operation: Hardened steel thrust buttons provide smooth and durable surface for pressure and floater plates. Testing: Every Tilton OT clutch is dynamically balanced to ensure the highest level of performance. Quality Assurance: Each OT clutch is individually inspected for proper assembly and balance, and initialed by the quality personnel as confirmation. Specifications:
