Upgrade the weak factory clutch in your 2000.5-2005.5 Dodge Ram 2500/3500 5.9L Cummins HO equipped with the NV5600 6-Speed manual transmission using the South Bend 1947-OFEK organic/feramic dual-friction single disc clutch kit. 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 complete kit ships with a heavy-duty South Bend flywheel, so you can ditch the weak factory dual-mass flywheel in the same install. Rated for approximately 475 hp, 1,000 ft-lbs, 25,000 lbs towing.
The South Bend 1947-OFEK is a organic/feramic dual-friction single disc clutch kit built specifically for 2000.5-2005.5 Dodge Ram 2500/3500 trucks running the 5.9L Cummins HO 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 dual-friction Organic/Feramic disc delivers a bump in holding power while staying surprisingly civil for a daily driver. 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.
Specifically designed for the 5.9L Cummins HO with the NV5600 6-Speed (1-3/8" / 1.375" 10-spline input shaft). Often used for performance street and heavy towing applications. Not recommended for stock applications in some contexts.
If you are seeing any of these symptoms, replace the clutch before further transmission or driveline damage occurs.
12-Month / 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-OFEK fit?
A: This kit is designed for 2000.5-2005.5 Dodge Ram 2500/3500 with the 5.9L Cummins HO 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 475 hp, 1,000 ft-lbs, 25,000 lbs towing. Real-world capacity depends on driving style, tune, and supporting modifications.
Q: Do I need to buy a flywheel separately?
A: No - this kit includes a brand-new South Bend solid-mass flywheel sized and machined for this clutch.
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.
