South Bend Clutch responded to the demand for an organic dual disc clutch by aiming to provide both durability and drivability. Drawing on 50 years of experience, they recognized the challenges of using all-organic materials in such a setup. The center plate in a dual disc clutch is much thinner than the pressure plate and flywheel, leading to higher heat buildup. Organic materials begin to fail around 550°F, while ceramic materials can withstand up to 1,100°F. Since the outer friction surfaces (pressure plate and flywheel) are thicker and dissipate heat better, organic materials work well there—but not on the thinner center plate, which overheats more easily. This is why a fully organic dual disc clutch is problematic.
South Bend Clutch heard the call for the organic dual disc clutch but wanted to offer the best in both durability and drive ability. How do they achieve that? In our 50 years of experience we knew that running an all organic dual disc would have it’s problems. The intermediate (center) plate is approximately 1/2″ thick whereas the pressure plate and flywheel castings are three times that. Running two friction surfaces on one thin casting will increase the temperature to that casting. Organic burn point is approximately 550 degrees whereas ceramic can reach 1,100 degrees. The immediate engagement points when the clutch is released for takeoff are the outside points of a dual disc clutch, pressure plate and flywheel. Being that there is only one friction surface running to these two points, and the fact that the pressure plate and flywheel castings are much thicker than the center plate, the temperatures cannot reach that of the center plate. This is why organic will work to the pressure plate and flywheel and not to the center plate.

Features
- Our 13″ diaphragm style 3250 lb. Pressure plate offers maximum holding power with easy pedal effort.
- The ceramic buttons will be facing the center plate. This will increase the holding power as well as increase the temperature capabilities to the intermediate plate.
- Clutch discs are a dampened free travel design similar to the semi clutch to help reduce gear roll over.
- Our one of a kind dampened center plate was designed to eliminate rattle when clutch is released.
- First in the clutch industry! We have developed organic friction in a button form allowing us to create a multi friction, dual disc clutch. The organic will be facing the pressure plate and flywheel for smooth engagement yet still offers superior holding power.
- Dual Disc for 550 hp, 1100 ft. lbs. torque
- Includes the Hyd-X-.750
