Upgrade the weak factory clutch in your 1988-2004 Dodge Ram 2500-3500 5.9L Cummins equipped with the Getrag 5-Speed manual transmission using the South Bend 13125-FER feramic 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 550 hp, 1100 ft-lbs, Not Recommended for Towing towing.
The South Bend 13125-FER is a feramic single disc replacement clutch kit built specifically for 1988-2004 Dodge Ram 2500-3500 trucks running the 5.9L Cummins engine paired with the Getrag 5-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 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.

This 13125-series kit fits multiple Dodge 5.9L Cummins year ranges and transmissions - please confirm yours before ordering:
This kit converts the factory 12.25" clutch to a 13" South Bend design - it requires the South Bend conversion flywheel (PN 167890-5) if your truck still has the OEM flywheel.
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.
This is a replacement clutch kit (REP) for existing South Bend installations. It will NOT fit a stock flywheel as it is a 13" upgrade. NV5600 fitment is limited to the 1999-2000.5 Non-HO (235hp) models with the 1.25" input shaft. Not recommended for towing due to aggressive Feramic engagement.
If you are seeing any of these symptoms, replace the clutch before further transmission or driveline damage occurs.
1-year / 12,000 miles 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 13125-FER fit?
A: This kit is designed for 1988-2004 Dodge Ram 2500-3500 with the 5.9L Cummins engine and Getrag 5-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 550 hp, 1100 ft-lbs, Not Recommended for Towing 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.
