Remanufactured 3781360 Cummins ISX / ISX15 Holset HE451VE Turbocharger with HOLSET OEM VGT Actuator

The 3781360 Turbocharger is a purpose-matched Holset HE451VE assembly for Cummins ISX, Cummins ISX15 heavy-duty highway and vocational applications. It is built around the exact compressor, turbine, housing, and control specification associated with part number 3781360, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 3781360 HE451VE is a heavy-duty Cummins ISX/ISX15 variable-geometry turbo designed for high airflow and precise exhaust-energy control. By changing vane position, the turbo can build boost quickly, regulate drive pressure at high load, and produce strong engine-brake backpressure when commanded. Correct installation includes checking the exhaust manifold, charge-air system, oil drain, crankcase pressure, and actuator calibration rather than replacing the turbo alone.

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.
