Availability
Tilton's 6-leg 5.5 Ultra clutch assemblies are a direct replacement or upgrade for the QM Optimum clutch—and they're Tilton's lightest weight 5.5 in. metallic racing clutch. The Ultras are designed and manufactured using proprietary materials and processes that increase service life of the clutch internals. They feature a rigid clutch cover that resists deflection, plus hardened steel thrust buttons installed into the legs—thus providing the most durability and highest performing clutch for the money, bar none. These clutches are rated for 500 lbs.-ft. of torque for two plate assemblies, and up to 750 lbs-ft. for three clutch units.

Tilton OT-III heavy-duty metallic racing 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. They're available with different plate count, flywheel type, and spring color options. * 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 in. 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
