OT-215 215mm (8.5”) Cerametallic Clutches are primarily designed applications such Pro Touring and Track Day cars that are regularly driven at racetrack events and driven occasionally on the road.  They offer a good compromise between larger diameter/heavier OEM-type clutches and smaller diameter/lighter 184mm (7.25”) racing clutches.   Compared to a 184mm (7.25” clutch) wint an equivalent number of discs an OT-215 Cerametallic Clutch provides approximately 50% more mass for increased heat capacity to keep overall clutch temperatures down, while providing higher torque capacity and better modulation.
OT-215 8.5” Cerametallic Clutches feature riveted friction buttons onto a heat-treated steel core plate.  This type of disc, compared to discs with sintered friction material*, better resists core plate cracking that can be caused by engine/transmission misalignment issues and/or engine harmonics.

* Friction material sintering process anneals core plate but allows for a thinner disc thickness and provides maximum friction surface area

The figures listed in the tables should only be used as a guide. Clutch selection needs to take into account the type of event it is being used for and what it is being fitted into. If you require and help making you clutch selection please call or email for guidance

Please Note:  Driven plates are not included and should be ordered seperately, by clicking the associated products link below,  a range of spline sizes are available from stock, if you are not certain of your requirement please contact us for assistance.

• 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: 7.85mm (0.309″) thick friction disc withstands elevated temperatures while providing low inertia and excellent wear resistance.
• 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.
