Product Overview
High-Performance HE300VG Turbocharger for QSB Tier 4 Industrial Equipment
- Designed for QSB Tier 4 Engines: This HE300VG turbocharger is developed for selected QSB Tier 4 and QSB6.7 CM2350 B105 engine applications. It helps restore the airflow and boost pressure needed for stable engine performance under demanding industrial loads.
- Variable Geometry Boost Control: The HE300VG adjusts the internal vane position according to engine speed and load. This helps improve low-speed response, maintain stable boost at higher engine speeds and support smoother power delivery during changing working conditions.
- Built for Off-Highway Equipment: QSB Tier 4 engines are used in excavators, wheel loaders, cranes, compactors, air compressors and material-handling equipment. This turbocharger is designed for machines that operate for long hours with frequent changes in hydraulic or mechanical load.
- Compatible with Modern Emission Systems: The turbocharger is matched to the airflow requirements of electronically controlled Tier 4 engines. Proper turbocharger operation supports the engine’s air-management system and helps maintain the boost response required for efficient combustion and emission control.
- Suitable for Replacement and Rebuild Projects: This unit is suitable for equipment maintenance, engine overhaul and fleet refurbishment. It can help address low power, slow response, excessive smoke, unusual turbo noise or VGT-related performance problems caused by a worn turbocharger.

Fitment Note: QSB Tier 4 engines may use different turbochargers depending on engine rating, CPL, control voltage and actuator design. Confirm the original turbocharger number, VGT actuator, electrical connector and housing configuration before purchase.
Q1: Does this HE300VG turbocharger fit all QSB Tier 4 engines?
No. QSB Tier 4 engines are available in different power ratings and equipment configurations. This turbocharger is intended for selected applications using the listed part numbers, such as 5327316, 3781639, 5327374 or 5501336. Check the original turbocharger identification plate and engine CPL before ordering.
Q2: What do the NX, RX, PX and RM suffixes mean?
These suffixes generally identify different service, exchange, remanufactured or replacement versions. They may have differences in condition, actuator configuration or service history. Match the complete turbocharger specification rather than relying only on the base number.
Q3: Does the turbocharger include the VGT actuator?
The actuator configuration depends on the specific product version. Confirm whether the actuator is included before ordering. If the original actuator is reused, it may require calibration or an electronic learn procedure after installation to match the new VGT mechanism.
Q4: What should be checked before installing the replacement turbocharger?
Replace the engine oil and filter, inspect the oil feed and drain lines, clean the air intake system and check the charge-air cooler for oil or debris. Inspect the exhaust after-treatment system for excessive restriction, prime the turbocharger with clean engine oil and perform the required VGT actuator calibration after installation.
Q5: Do you provide worldwide shipping?What is the delivery timeframe?
We ship globally via premium carriers like DHL,FedEx,and UPS,as well as sea freight for bulk orders.In-stock items are typically dispatched within 24-48 hours. Express delivery to North America and Europe usually takes 5-7 business days.
