Drivetrain
South Bend Street Dual Disc All Organic Clutch, 550hp, 1200 torque – 05.5-18 Dodge G56 (SDD3250-GK-ORG) for 2005.5-2018 Cummins 6.7L
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.
