Heavy-Duty GTA5523S Turbocharger for QSX15 Agricultural Engines (STX530)

• Agricultural-Grade Power Restoration: Specifically engineered for high-displacement QSX15 (15L) engines used in heavy agricultural tractors. Technical Benefit: Restores full boost pressure for ultra-high-torque field operations, ensuring your STX530 maintains peak pulling power during the most demanding seasons.
• Direct "Drop-In" Replacement: A 1:1 mechanical match for original brand GTA5523S units. Fully compatible with factory 761064-5007S mounts, oil cooling lines, and intake manifolds—ensuring a seamless installation in the field or workshop.
• Oversized K18 Nickel-Alloy Turbine: Features a premium K18 alloy turbine wheel designed to handle the massive exhaust energy and sustained heat of 500+ horsepower agricultural applications without blade deformation or structural failure.
• VSR High-Speed Dynamic Balancing: 100% dynamic balancing tested on a Vibration Sorting Rig (VSR) at full operational RPMs. This eliminates shaft vibration at high boost levels, protecting your engine's bearings and ensuring ultra-smooth power delivery.
• Maximum Uptime Reliability: Manufactured under IATF 16949 standards by Zhongke Turbo. Provides a high-reliability, cost-effective alternative to expensive dealership parts, keeping your agricultural fleet moving when every hour of sunlight counts.
