Industrial-Grade HX80M Marine Turbocharger for Cummins K19, KTA19, and K38 Engines
- Heavy-Duty Marine Design: Engineered specifically for the Cummins K-Series (19L & 38L) marine engines. This HX80M unit provides the massive airflow required for M640 power ratings and high-torque marine propulsion.
- Direct OEM Replacement: A 1:1 "drop-in" fit designed to replace original Holset HX80M units. Fully compatible with factory marine water-cooling lines and heavy-duty exhaust manifolds—ensuring zero-modification installation on your vessel.
- K18 Nickel-Alloy Turbine Wheel: Features an oversized K18 Nickel-Alloy turbine wheel, designed to withstand continuous exhaust temperatures exceeding 950°C without blade deformation—critical for the 24/7 duty cycles of commercial marine operations.
- Precision VSR Balancing: Every HX80M undergoes 100% dynamic balancing on a Vibration Sorting Rig (VSR). Technical Benefit: This eliminates vibration (crucial for shipboard comfort and structure), reduces bearing noise, and maximizes the service life of your engine in open-sea conditions.
- Corrosion Resistant Coating: The compressor and turbine housings are treated for enhanced resistance against saltwater corrosion and high-humidity marine environments.

FAQs
Q1: How do I verify if this turbo fits my vessel's engine?
Marine turbos are application-specific. Please check the nameplate on your old turbocharger for the part number 3596959 or the Cummins OEM number 4025301. Because Cummins often uses "RX" or "NX" for remanufactured units, matching the base numbers is the most reliable way to ensure 100% fitment.
Q2: What is the benefit of the HX80M "Water-Cooled" design?
In a marine engine room, surface temperatures must be kept low for safety. The HX80M water-cooled housing significantly reduces radiant heat, prevents fire hazards, and keeps the engine room temperature manageable during long voyages.
Q3: Is this a brand new unit or remanufactured?
This is a 100% brand new, factory-direct unit. While many marine suppliers only offer remanufactured (RX) units at high prices, we provide a brand new alternative that meets or exceeds original factory specifications.
Q4: What maintenance is critical for Cummins Marine turbos?
Lubrication and Cooling. Always use the recommended marine engine oil and ensure your Sea Water Cooling System (heat exchanger) is clear of debris. Before a long voyage, we recommend inspecting the Oil Feed Line to ensure the heavy-duty bearings receive maximum flow.
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.
