Industrial-Grade HX55W Wastegate Turbocharger for QSM11 (11L) Tier 3 Engines

• Precision Wastegate Calibration: Specifically engineered for the QSM11 (11-liter) Tier 3 emission platform. Technical Benefit: Provides a steady and controlled boost response under heavy industrial loads, ensuring your wheel loader or truck maintains maximum torque without the risk of over-boost engine damage.
• Direct "Drop-In" Replacement: A 1:1 mechanical match for original Holset HX55W units. Fully compatible with factory 4037635 and 4037636 mounts, oil lines, and Tier 3 exhaust interfaces—ensuring a zero-modification installation for fleet maintenance teams.
• K18 Nickel-Alloy Turbine Wheel: Equipped with a high-grade K18 alloy turbine wheel, designed to withstand the continuous high exhaust temperatures of 11L industrial engines without blade deformation or structural fatigue.
• VSR Precision Balancing: 100% dynamic balancing tested on a Vibration Sorting Rig (VSR) at full operational RPMs. This eliminates shaft micro-vibration, ensuring ultra-quiet power delivery and maximizing the service life of the precision journal bearings.
• Tier 3 Rugged Reliability: Manufactured to meet IATF 16949 standards by Zhongke Turbo, providing a high-reliability, cost-effective alternative to expensive dealership parts while maintaining original equipment uptime in harsh construction environments.

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.
