High-Performance GT2256MS Turbocharger for NPR & NQR Highway Trucks

• Designed for the 4HG1T Engine: This GT2256MS turbocharger is developed for 4HG1T 4.6L turbocharged diesel engines. It helps restore the boost pressure needed for normal acceleration, stable engine operation and reliable performance under load.
• Built for Commercial Truck Use: NPR and NQR trucks are commonly used for delivery, transport, construction support and municipal service. This turbocharger is designed to provide steady airflow during stop-and-go driving, highway travel and loaded operation.
• Responsive Performance at Working Speeds: The GT2256MS is matched to the airflow requirements of the 4HG1T engine. It supports useful torque at low and medium engine speeds, helping the truck pull away smoothly and maintain speed when carrying cargo.
• Direct Replacement Configuration: The unit is designed as a replacement for the original turbocharger used in the listed applications. The mounting points, oil connections and air outlet arrangement should be compared with the original unit before ordering.
• Suitable for Fleet Maintenance: This turbocharger is suitable for commercial vehicle workshops, fleet repair departments and truck refurbishment projects. It can help address low boost, poor acceleration, excessive smoke, oil leakage or unusual turbocharger noise caused by a worn unit.
