FAQ
Will this clutch fit my 1994–2003 Cummins with the NV4500?Yes. It is designed for 5-speed NV4500 trucks (Ram 2500/3500) with the 5.9L Cummins, model years 1994–2003.
Is a 1.375" input shaft required?
No. This kit uses a 1.25" hub. A 1.375" input is a durability upgrade if you plan to move into higher-clamp or dual-disc clutches later. See the CPP Extreme Duty NV4500 1.375" input shaft linked above.
Do I need to upgrade hydraulics?
Healthy OEM hydraulics can work, but higher clamp loads and age can make engagement inconsistent—upgraded hydraulics (linked above) are recommended for best pedal feel and release.
What break-in is recommended?
Typical break-in is ~500 miles of easy stop-and-go driving with no hard launches or sled pulls to seat the disc surfaces evenly.
