Product Description
The Cummins 4031484 OEM Holset HE341/HE351CW Turbo Rebuild Kit is the genuine service kit used to restore factory performance and reliability in the stock turbocharger found on 2003–2007 Dodge Ram 2500/3500 5.9L ISB Cummins engines. This is the exact Holset/Cummins-approved kit containing the correct bearings, seals, and thrust components designed specifically for the HE341 and HE351CW turbochargers—ensuring proper rotor balance, oil control, and long-term durability.
Unlike aftermarket kits that often mix generic components, the 4031484 OEM kit provides matched materials and precision tolerances engineered for high-load diesel applications. This guarantees correct oil metering, boost response, and longevity whether you're rebuilding for routine maintenance or restoring a worn high-mileage charger.

FAQ
Does this 4031484 kit fit both HE341 and HE351CW turbos?
Yes. Cummins engineered this OEM kit for both HE341 and HE351CW turbochargers used on 2003–2007 5.9L Cummins trucks.
Does the kit include a new turbine or compressor wheel?
No. This is a CHRA bearing/seal rebuild kit. Wheels, housings, and actuators are not included.
Can I rebuild my turbo at home?
Rebuilding requires professional balancing equipment. The kit supplies OEM internals, but Cummins recommends machine-balanced reassembly.
Is this kit superior to aftermarket rebuild kits?
Yes. OEM Holset/Cummins kits use proper metallurgy and precise tolerances, ensuring correct oil metering, thrust load capacity, and reliability.
Should I replace the oil feed line when rebuilding the turbo?
