High-Performance HX40W Turbocharger for ISC Powered Trucks & RVs

• Built for 8.3L Power: This HX40W unit is the primary boost solution for the ISC 8.3L engine platform. It is engineered to handle the sustained high-load demands of medium-duty freight hauling and motorhome travel, ensuring your ISC maintains its rated torque curve and climbing ability without excessive EGTs (Exhaust Gas Temperatures).
• Heat-Resistant Turbine Housing: We utilize a high-nickel ductile iron for the turbine housing, specifically chosen for its resistance to thermal fatigue. This ensures the housing won't crack or warp during the long, hot duty cycles common in cross-country trucking, maintaining a tight seal for maximum turbo efficiency.
• High-Speed VSR Balancing: To prevent premature bearing failure, every HX40W center section (CHRA) is balanced on a high-speed Vibration Sorting Rig (VSR). By eliminating shaft oscillation at speeds up to 150,000 RPM, we ensure the journal bearings stay lubricated and stable, significantly extending the service life of the unit.
• Enhanced Low-End Response: The internal compressor aerodynamics are tuned for the ISC’s airflow requirements. This allows for quicker spool-up at lower RPMs, providing the immediate "get-up-and-go" power needed when merging onto highways or pulling heavy trailers from a dead stop.
• Pre-Set Wastegate Calibration: The internal wastegate and pneumatic actuator are factory-calibrated to match ISC engine control maps. It is a true "bolt-on" replacement—all mounting flanges and oil connections are 1:1 matches to 4089930 specs, requiring no modifications to the manifold or intercooler piping.

Fengcheng Zhongke Turbocharger Co., Ltd. is a leading high-tech factory specializing in the R&D, production, and global distribution of high-performance turbochargers. Based in Fengcheng—one of the world’s most renowned turbocharger manufacturing hubs—we have grown from a local workshop into a global supplier, serving heavy-duty, commercial, and passenger vehicle markets worldwide.

At Zhongke, we don't just "make" parts.we engineer reliability.

• Material Integrity: We exclusively use K18 Nickel-Alloy turbine wheels, capable of withstanding extreme exhaust temperatures (up to 950°C) without deformation.
• Dynamic Balancing: 100% of our turbochargers undergo high-speed dynamic balancing tests at 150,000+ RPM to guarantee zero vibration and extended bearing life.
• Certified Quality: Our production processes are certified under ISO 9001 and IATF 16949, the gold standards for the global automotive and heavy-machinery industries.

Manufacturing Prowess:Our facility is equipped with state-of-the-art production lines, including precision 5-Axis CNC machining centers, high-speed VSR (Vibration Sorting Rig) balancing machines, and advanced material testing labs.

Our Specialization:We maintain a vast inventory of over 3,500+ turbocharger models, with a focus on heavy-duty and construction machinery engines. Focused on optimizing fuel efficiency and restoring factory horsepower, our passenger car turbos are engineered with the same precision and K18 heat-resistant materials as our industrial line, ensuring reliable performance for daily commuting and high-speed driving alike.
