Clutch Kits

OT-215 8.5” Cerametallic Clutches are primarily designed applications such Pro Touring and Track Day cars that are regularly driver at racetrack events and driven occasionally on the street.  They offer a good compromise between larger diameter/heavier (10.5”/11”) OEM-type clutches and smaller diameter/lighter 7.25” racing clutches.   Compared to the equivalent number of disc 7.25” clutch, OT-215 8.5” Cerametallic Clutches provide 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

Open, one-piece clutch cover design provides lower operating temperature, high strength and minimal deflection for quick shifting.

Chrome vanadium diaphragm springs and an engineered pressure plate geometry provide a high clamp load-to-wear ratio, low release load, and quick shifting.

High-strength steel is used in both the pressure plates and the floater plates.

.309″-thick friction disc withstands elevated temperatures while providing low inertia and excellent wear resistance.

Every Tilton OT clutch is dynamically balanced to ensure the highest level of performance.

Each OT clutch is individually inspected for proper assembly and balance, and initialed by the quality personnel as confirmation.

Featuring an aluminum clutch cover that shares technology from Tilton’s championship-winning line of OT- Series racing clutches, ST-246 clutches feature heavy-duty straps that attach the pressure plate and floater plate to minimize noise. ST-246 clutches are available with either sprung-hub organic discs for street applications or solid-hub cerametallic discs for street/strip applications.
