South Bend 1947-OK-HD Heavy Duty Organic Clutch Kit with Flywheel | 2000.5-2005.5 Dodge 5.9L Cummins NV5600

Upgrade the clutch in your 2000.5–2005.5 Dodge Ram 2500 or 3500 with the South Bend 1947-OK-HD Heavy Duty Clutch Kit. This premium single-disc organic clutch is specifically engineered for the 5.9L Cummins High Output (HO) engines paired with the NV5600 6-speed manual transmission.

Built as South Bend’s Heavy Duty (HD) series, this clutch delivers the perfect balance of increased holding power and excellent street manners. It features a 13" clutch disc with a full 3" wide premium organic lining and a heavy-duty 6-spring dampened hub for smooth, positive engagement. The pressure plate uses an extra-wide casting design borrowed from South Bend’s street dual-disc clutches, providing higher clamp load without excessive pedal effort.

Rated for up to 425 horsepower and 900 ft-lbs of torque, the 1947-OK-HD is an ideal choice for trucks with moderate performance upgrades that still see regular or heavy towing duties. Owners appreciate the smooth take-off, light pedal feel, and reliable performance whether daily driving or pulling heavy loads.
