High-Performance GT2256S Turbocharger for Loaders & Off-Highway Equipment

• Industrial-Strength Performance: This GT2256S unit is specifically engineered for the high-duty cycles of loaders and off-highway machinery. It provides the consistent boost pressure required for the C4.4 Tier 4 engine platform, ensuring your equipment maintains peak breakout force and lifting capacity even under heavy 24/7 operating conditions.
• Precision-Balanced Core: To guarantee long-term reliability in dusty construction environments, each turbocharger undergoes rigorous Vibration Sorting Rig (VSR) balancing at speeds exceeding 150,000 RPM. This eliminates high-frequency vibrations that lead to shaft fatigue and premature journal bearing wear.
• Thermal Fatigue Resistance: The turbine housing is manufactured from high-nickel ductile iron, designed to withstand the rapid thermal cycling typical of off-highway equipment. This prevents housing cracks and wastegate binding, ensuring the internal components remain structurally sound at operating temperatures exceeding 750°C.
• Direct OEM Bolt-On: This is a precision 1:1 replacement for Garrett and factory units. All oil feed ports, coolant connections, and mounting flanges are machined to exact 356-3519 and 479-5809 specifications, allowing for a seamless "drop-in" installation without modifying the exhaust manifold or charge air piping.
• Optimized Low-End Response: The internal compressor wheel aerodynamics are tuned for the 4.4L displacement. This provides a sharp boost curve at lower RPMs (2200 range), which is critical for loaders that require immediate hydraulic response and drive-train torque for scooping and maneuvering.

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.
