FAQs

Q1: How do I verify if this HX30W turbocharger fits my Cummins 4BT engine? 

Please check the nameplate on your current turbocharger for the part number 4040353 or the Cummins OEM number 3960907. Since the 4BT engine has dozens of build configurations, matching the 7-digit Cummins part number is the most reliable way to ensure a correct fit.

Q2: Does this turbocharger include the wastegate actuator? 

Yes. Our HX30W comes with a pre-calibrated wastegate actuator to ensure safe boost levels and prevent engine over-pressurization, making it a complete, ready-to-install unit.

Q3: What makes Zhongke’s turbochargers reliable for industrial and swap projects? 

The 4BT is known for high vibration. We use genuine K18 nickel-alloy turbine wheels and perform VSR high-speed balancing to ensure our turbos can handle the mechanical stress and thermal loads of the 4BT platform without premature failure.

Q4: What type of warranty do you provide for professional engine builders and fleet managers? 

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