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-FEK feramic 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 550 hp, 1100 ft-lbs, Not recommended for heavy towing (dual disc preferred for heavy loads) towing.
The South Bend 13125-FEK is a feramic single disc 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.
Converts factory 12.25" setup to a larger 13" setup. Fits 5-speed transmissions and early 6-speed Non-HO models. Requires specific flywheel included in the kit. Not recommended for stock applications or heavy towing (dual disc recommended for regular 15k+ lbs towing at this HP level).
If you are seeing any of these symptoms, replace the clutch before further transmission or driveline damage occurs.

Q: What trucks does the 13125-FEK 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 heavy towing (dual disc preferred for heavy loads) 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.
