Remanufactured 4309078 Cummins ISX / ISX15 Holset HE561VE Turbocharger with HOLSET OEM VGT Actuator

The 4309078 Turbocharger is a purpose-matched Holset HE561VE assembly for Cummins ISX CM871 high-horsepower calibration, Cummins ISX15 applications where specified. It is built around the exact compressor, turbine, housing, and control specification associated with part number 4309078, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 4309078 is an HE561VE calibration used on higher-horsepower Cummins ISX CM871 applications. The larger airflow requirement makes compressor condition, vane movement, actuator control, and charge-air integrity especially important under sustained load. The turbo is designed to provide strong top-end air delivery while still supporting low-speed response and engine-brake operation through electronic vane control.

This complete version includes a HOLSET OEM VGT actuator matched to the turbocharger. The actuator and vane mechanism are checked for full travel and correct indexing so the assembly can be installed as a complete unit; the vehicle's required calibration or learn procedure must still be completed after installation. Turbo Centre remanufacturing begins with complete disassembly and thorough cleaning so every critical surface can be inspected. Worn bearings, seals, and service components are replaced; shaft, wheel, housing, and vane-system condition are measured; the rotating assembly is balanced; and the completed turbo is checked for smooth operation, oil sealing, and correct control movement before shipment. This process restores the unit as a complete engineered assembly rather than simply replacing the visibly damaged component.
