FAQs

Q1: How do I verify if this HE300VG turbocharger fits my QSB engine? 

Please check the nameplate on your current turbocharger for the part number 5327316 or 3781639. Cummins Tier 4 engines are extremely specific about turbo configurations. If the nameplate is missing, please provide your Engine Serial Number (ESN) to our support team for a free fitment audit.

Q2: Is the electronic VGT actuator included? 

Our HE300VG typically comes with a high-precision actuator that is factory-tested. For Tier 4 engines, ensure your machine’s software is ready to calibrate with the new unit upon installation to ensure optimal vane movement.

Q3: What makes Zhongke’s VGT turbos reliable for off-road work? 

Off-road equipment operates in high-vibration and high-dust environments. We use genuine K18 nickel-alloy wheels and precision-machined VGT components to ensure our turbos can handle constant load changes and intense heat without seizing.

Q4: What type of warranty do you provide for industrial-grade units? 

As a direct manufacturer with nearly 30 years of experience, we provide full technical support for equipment owners and maintenance fleets worldwide.

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.
