The OE 4043980 turbocharger is a genuine Holset HE351W model, engineered as the original equipment component for Cummins 6ISBE series diesel engines. Manufactured by Holset, a world-renowned turbocharger brand under Cummins, this unit delivers factory-matched performance and reliability for commercial vehicle fleets and heavy equipment operators. Designed to meet China III and China IV emission standards, it is the preferred replacement turbocharger for Dongfeng Tianlong, Dongfeng Tianjin and other medium-heavy duty trucks powered by Cummins engines.
The HE351W turbocharger acts as a precision air compressor, utilizing engine exhaust gases to drive a turbine wheel that spins a connected compressor wheel. This process compresses fresh intake air, allowing significantly more fuel to be burned efficiently in the combustion chamber. The result is a 30%+ increase in engine horsepower and torque, enabling your commercial vehicles to handle heavy loads and steep gradients with ease.
By improving the air-fuel mixture ratio and combustion efficiency, the OE 4043980 turbocharger reduces fuel consumption across all operating conditions. This translates directly to lower operating costs for commercial fleets, with measurable savings in annual fuel expenses. The turbocharger's advanced design also minimizes turbo lag, ensuring responsive acceleration and smoother power delivery.
This genuine Holset turbocharger features a robust wastegate system that precisely controls boost pressure, preventing over-boosting and protecting your Cummins 6ISBE engine from damage. The high-quality cast iron turbine housing withstands extreme exhaust temperatures, while the precision-balanced rotating assembly ensures long service life even under continuous heavy-duty operation.

To maximize the service life of your HE351W turbocharger:
Use only high-quality engine oil meeting Cummins specifications
Change engine oil and filters at recommended intervals
Allow the engine to idle for 3-5 minutes before shutdown to cool the turbocharger
Inspect intake and exhaust systems regularly for leaks or restrictions
OE 4043980 and 4043982 are interchangeable Holset HE351W turbocharger models designed for Cummins 6ISBE engines. They feature identical performance characteristics and fitment, with minor production variations that do not affect operation.
Yes, the OE 4043980 turbocharger is the original equipment unit for Dongfeng Tianlong trucks equipped with Cummins 6ISBE series diesel engines meeting China III and China IV emission standards.
When properly installed and maintained, the HE351W turbocharger delivers a minimum 30% increase in engine horsepower and torque compared to a naturally aspirated engine of the same displacement.
With proper maintenance and operation, the genuine Holset OE 4043980 turbocharger has a service life of 150,000-200,000 kilometers under normal commercial operating conditions.
While experienced mechanics can perform the installation, we recommend professional installation by a qualified Cummins service technician to ensure proper fitment, calibration and warranty coverage.
