Product Overview
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.

Q1: Does this GT2256MS turbocharger fit the NPR and NQR?
Yes, it is intended for selected NPR and NQR trucks equipped with the 4HG1T engine and matching references such as 704136-5003S, 8973267520 or 8972083520. Confirm the original turbocharger number and mounting configuration before ordering.
Q2: Are 8973267520 and 8972083520 interchangeable numbers?
These numbers are commonly listed as reference numbers for this GT2256MS turbocharger application. To confirm compatibility, compare the complete turbocharger, including the turbine housing, compressor outlet, oil inlet and oil drain positions.
Q3: Can this turbocharger be used on a naturally aspirated 4HG1 engine?
No. This turbocharger is intended for the turbocharged 4HG1T or 4HG1-T engine. A naturally aspirated engine may have different compression, exhaust manifold and oil supply arrangements, so the engine type must be verified before installation.
Q4: What should be checked before installing the replacement turbocharger?
Replace the engine oil and filter, inspect the oil feed and drain lines, clean the air intake system and check the intercooler or charge-air pipes for oil and debris. Prime the turbocharger with clean engine oil before starting the engine, then check the intake, exhaust and oil connections for leaks.
Q5: Do you provide worldwide shipping?What is the delivery timeframe?
We ship globally via premium carriers like DHL,FedEx,and UPS,as well as sea freight for bulk orders.In-stock items are typically dispatched within 24-48 hours. Express delivery to North America and Europe usually takes 5-7 business days.
