High-Output HX55W Wastegate Turbocharger for ISM (11L) Engines

• Precision Wastegate Control: Features a heavy-duty HX55W wastegate actuator, specifically calibrated for the ISM 11-liter platform. Technical Benefit: Precisely manages boost pressure to prevent engine over-speeding, optimizes mid-range torque for heavy busses and trucks, and ensures consistent highway performance.
• Direct "Drop-In" Installation: A 1:1 mechanical match for original Holset HX55W units. Fully compatible with factory mounts, oil cooling lines, and EPA-spec exhaust interfaces—ensuring a seamless replacement for fleet technicians.
• K18 Nickel-Alloy Turbine Wheel: Equipped with a high-grade K18 Nickel-Alloy turbine wheel, designed to withstand the sustained high exhaust temperatures and intense pressures of 11L diesel engines without blade creep or fatigue.
• VSR High-Speed Dynamic Balancing: 100% vibration tested on a Vibration Sorting Rig (VSR) at operational RPMs. This process eliminates shaft runout, ensures whisper-quiet operation, and significantly extends the service life of the precision bearings.
• Fleet-Grade Durability: Manufactured under IATF 16949 quality standards by Zhongke Turbo. Provides a high-reliability, cost-effective alternative to expensive OEM dealership parts while maintaining original equipment uptime for long-haul and industrial fleets.

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.
