Cummins 5458147 Turbocharger Kit HE400VG

The Cummins 5458147 is a genuine OEM turbocharger kit featuring the Holset HE400VG variable geometry turbocharger assembly. Designed for Cummins QSL 8.9L and 9.0L diesel engines, this unit integrates an electronic VGT actuator for precise boost control across the operating range. The kit includes the turbocharger cartridge (CHRA), turbine housing, compressor housing, and necessary installation gaskets and hardware. Engineered for heavy-duty commercial truck, construction equipment, and industrial power generation applications, the HE400VG utilizes a water-cooled bearing housing and high-temperature alloy turbine wheel to withstand sustained high exhaust gas temperatures. The variable nozzle geometry reduces turbo lag at low RPM while preventing over-boost at high load. This assembly replaces Cummins part numbers 5354730 and 3790310. Professional installation with calibrated actuator setup is required to ensure emissions compliance and engine performance parameters.
