Upgrade the weak factory clutch in your 2000.5-2005.5 Dodge Ram 2500-4500 5.9L Cummins HO / 24V equipped with the NV5600 6-Speed manual transmission using the South Bend 1947-O organic single disc replacement clutch kit (no flywheel). Engineered specifically for this engine and transmission combination, this kit delivers smoother engagement, far better holding power, and long-term durability over the original setup.
This is a REPLACEMENT kit and does NOT include a flywheel - it is designed for trucks that already have a South Bend solid-mass flywheel installed. If your truck still has the factory flywheel, you will need the version of this kit that includes one. Rated for approximately 400 hp (also seen as 375 hp on some dealer sites), 800 ft-lbs, 15,000 lbs (seen up to 25,000 lbs for hybrid OFE variants) towing.
The South Bend 1947-O is a organic single disc replacement clutch kit built specifically for 2000.5-2005.5 Dodge Ram 2500-4500 trucks running the 5.9L Cummins HO / 24V engine paired with the NV5600 6-Speed manual transmission. This is one of the most critical fitment details on these trucks - the same year and engine combination was offered with multiple transmissions, so always confirm your transmission code before ordering.
The organic friction lining gives you smooth, street-friendly engagement and excellent heat resistance for towing and daily driving. The sprung hub design absorbs drivetrain shock at engagement and protects your transmission and driveline from harsh take-offs.

2000.5-2005.5 Dodge 5.9L HO trucks were only sold with the NV5600 6-Speed manual. This kit fits the HO (High Output) engine with the 1-3/8" (1.375") 10-spline input shaft. If your truck has the NV4500 5-Speed, you have an earlier 1998.5-2000.5 Non-HO 24V engine - use the 13125 series instead.
IMPORTANT - REPLACEMENT KIT ONLY: This part number is a replacement kit and does NOT include a flywheel. It is designed for trucks that already have a South Bend solid-mass flywheel installed. It will NOT work with the factory OEM flywheel. If your truck still has the stock flywheel - or you don't know - choose the matching full kit (the version of this part number that ends in -K, -OK, -OFEK, etc.) instead, or call us before ordering.
Specifically designed for High Output (HO) engines with NV5600 6-speed transmission. The "O" in the part number denotes Organic friction material. The kit 1947-O is sold without a flywheel, while 1947-OK includes the flywheel. Fits 1-3/8" (1.375") 10-spline input shafts. Requires 13" conversion if replacing stock 12.25" components.
If you are seeing any of these symptoms, replace the clutch before further transmission or driveline damage occurs.
1-year / 12,000 mile from the date of purchase, covering manufacturing defects in materials and workmanship. Applies to the original purchaser only. Proper installation, break-in, and flywheel resurfacing (when reusing a flywheel) are required for warranty validity. For exact terms refer to South Bend Clutch's current warranty policy at time of purchase.
Q: What trucks does the 1947-O fit?
A: This kit is designed for 2000.5-2005.5 Dodge Ram 2500-4500 with the 5.9L Cummins HO / 24V engine and NV5600 6-Speed manual transmission. See the application notes above if your year/engine combination came with more than one transmission.
Q: How much power and towing can it handle?
A: South Bend rates this kit for approximately 400 hp (also seen as 375 hp on some dealer sites), 800 ft-lbs, 15,000 lbs (seen up to 25,000 lbs for hybrid OFE variants) towing. Real-world capacity depends on driving style, tune, and supporting modifications.
Q: Do I need to buy a flywheel separately?
A: Yes - this is a replacement kit that does NOT include a flywheel. It is designed for trucks that already have a South Bend solid-mass flywheel installed. If your truck still has the OEM flywheel, choose the full kit with flywheel included or contact us for guidance.
Q: Is this clutch OK for daily driving?
A: Yes - the disc material and pressure plate are tuned for street-friendly engagement and reasonable pedal effort. Aggressive race-style clutches usually carry the ceramic or full-face puck designation; this kit is built for daily use, towing, and mild performance.
Q: What is the recommended break-in period?
A: South Bend typically recommends 500-1,000 miles of easy, mixed driving with no hard launches or heavy towing so the friction surfaces properly seat. Skipping the break-in can void your warranty.
Q: Do I need anything else to install it?
A: We strongly recommend inspecting and replacing the hydraulic master and slave cylinders, pilot bearing, and checking the throwout bearing fork at the same time. Always use the alignment tool included in the kit. If you are reusing a flywheel, it must be properly resurfaced.
