114400-3140 RHC7-12307HQ41NFBRL6424CC TURBOCHARGER FOR ISUZU 6SD1T(CIAQ) HITACHI EX300-1
Our replacement turbochargers are not just components; they are critical power units designed and manufactured to meet and significantly exceed the relentless operational demands of commercial diesel engines and heavy-duty fleet applications. In the rigorous world of transportation, where downtime is measured in lost revenue, our focus is on delivering uncompromising reliability and sustained peak performance.
| Feature | Technical Detail | Direct Customer Benefit |
| Superior Transient Response | Advanced Billet or Forged Compressor Wheels and Optimized Aerodynamic Flow Paths. | Eliminates Turbo Lag: Delivers immediate, consistent torque for safer merging, easier hill climbs, and reduced stress on the drivetrain. |
| Engine Longevity | Effective Thermal Management and Robust High-Temperature Alloy Housings. | Extends Component Life: Significantly lowers Exhaust Gas Temperatures (EGTs), protecting critical engine parts like pistons, cylinder heads, and exhaust valves from premature failure and cracking. |
| Optimized Total Cost of Ownership (TCO) | Premium Aftermarket Quality with Strategic, Competitive Pricing. | Maximizes ROI: Achieve reliability and power profiles comparable to or exceeding OEM specifications at a fraction of the cost, improving fleet profitability. |
| Guaranteed Durability | Vibration Sorting Rig (VSR) Multi-Stage High-Speed Balancing (< $0.5 \text{mg}$ Tolerance). | Zero-Vibration Operation: Guarantees extended bearing life, reduces noise, and ensures consistent boost delivery over hundreds of thousands of miles. |
Quality assurance in a turbocharger operating at $200,000 \text{ RPM}$ is paramount. We integrate cutting-edge manufacturing techniques and stringent testing protocols into every phase of production.
Every Central Rotating Housing Assembly (CHRA) is subjected to a proprietary, three-stage balancing process:
Component Balancing: Individual compressor wheels, turbine wheels, and shafts are statically and dynamically balanced to isolate and correct initial imbalances.
VSR High-Speed Testing: The fully assembled CHRA unit is tested on a state-of-the-art Vibration Sorting Rig (VSR). This process simulates real-world engine speeds under oil pressure, identifying and correcting residual imbalances to an industry-leading tolerance of less than $0.5 \text{ mg}$. This meticulous process is the definitive safeguard against catastrophic bearing failure and audible operational noise.
Flow Bench Calibration: After balancing, the Variable Geometry Turbocharger (VGT) components, where applicable, are calibrated on a flow bench to ensure precise air delivery and boost response across the full operational map, matching or exceeding OEM flow metrics.
Our selection of materials is determined by the need to withstand extreme thermal, mechanical, and pressure stresses:
Turbine Wheel Material: Constructed from high-nickel superalloys, such as Inconel 713C or 718, providing exceptional resistance to thermal creep, high-temperature corrosion, and mechanical fatigue within the high-heat exhaust gas stream.
Compressor Wheel Technology: We primarily utilize Billet (Forged) aluminum alloy for our compressor wheels. The forging process enhances the material’s grain structure, providing superior strength, allowing for thinner blades, reduced rotational mass, and complex geometries that significantly improve aerodynamic efficiency and reduce spool time.
Housing Integrity: Compressor and turbine housings are cast using specialized materials: SiMo Ductile Iron for enhanced temperature resistance in turbine sections and high-grade aluminum for compressor sections, ensuring dimensional stability and sealing efficiency.
We understand that fleet maintenance often requires granular component replacement rather than full unit substitution. We function as a full-spectrum supplier, supporting the remanufacturing and service industry with high-quality, reliable individual components.

Seamless Sourcing: Our broad compatibility and extensive inventory simplify your procurement process, drastically cutting down the lead times often associated with specialized OEM parts.
We believe in a partnership approach. Providing the highest quality component is only half the battle; ensuring it is installed correctly is paramount to achieving maximum service life.
Failure to follow these steps is the leading cause of premature turbo failure and will void warranty claims:
Forensic Diagnosis: Before removing the old unit, thoroughly investigate the precise cause of its failure (e.g., oil restriction, foreign object impact, excessive EGTs from poor tuning). The root cause must be corrected.
System Integrity Check: Flush the engine oil cooler, replace all oil filters, air filters, and ensure the intercooler and exhaust manifolds are free of debris, carbon build-up, or blockages that could impede flow.
Oil Priming Procedure (Non-Negotiable): MANUALLY inject clean, correct-specification engine oil into the turbo’s oil inlet port and spin the compressor wheel by hand. This pre-lubrication prevents momentary, catastrophic oil starvation during the engine’s initial start-up before full oil pressure is established.
Component Replacement: Always use new gaskets, O-rings, and specialized seals. Never reuse old sealing components.
We confidently back our products with a standard 12-month warranty against any failure resulting from defects in our manufacturing process, materials, or workmanship.
Claim Process: Upon a reported failure, we require a detailed technical report, often including photographic evidence. Our engineering team conducts a swift, transparent analysis. If the defect is confirmed, we immediately dispatch a replacement unit or issue a full credit.
Exclusions: Our warranty explicitly excludes failures caused by external factors beyond our control, including: Oil Starvation/Contamination (dirty oil, low pressure), Foreign Object Damage (FOD), incorrect installation, engine over-speeding, or improper tuning that results in excessive operational temperatures.
Our infrastructure is built to support your global supply chain needs, offering speed and flexibility.
Flexible Ordering Policy: We operate with No Minimum Order Quantity (MOQ) for standard catalog parts. We actively encourage small sample orders for quality control and validation by your engineering teams before committing to volume purchases.
Worldwide Shipping Solutions: We utilize standard International Commercial Terms (Incoterms), typically defaulting to EXW (Ex Works) or FOB (Free On Board). We offer diversified shipping solutions: Air Express (for urgent, small orders, 5–10 days), Air Freight (for medium-sized shipments), and Sea Freight (for bulk, cost-optimized orders, 3–6 weeks).
Technical Sales Support: Our sales engineers are experienced technicians, not just order takers. They are prepared to assist with part cross-referencing, compatibility checks, and initial troubleshooting guidance, ensuring you get the right solution the first time.
Do Not Wait for Component Failure—Upgrade Today for Superior Efficiency and Durability.
We provide a wide range of turbocharger spare parts to support both remanufacturing and repairs. Our product lineup includes practically everything you might need. Here are some of the key parts we offer:
These spare parts cover most major turbocharger brands and models for commercial diesel engines as well as passenger vehicles. If you’re looking for something specific, just let us know the turbo model or the OEM part number, and we’ll quickly check if we have it available.
Making sure you get the right part is really important. The best way is to use the original equipment manufacturer (OEM) part number or your turbo’s model number as a reference when you order. Every turbocharger usually has an ID tag or an engraved number on it — if you give us that info, we can find the exact spare part you need.
Our sales engineers are also ready to help. If you let us know your engine model, the turbo’s model (or serial number), and maybe what problem you’re trying to fix or which component you’re replacing, we can cross-check and guide you to the right part. This way you’ll have a correct match and avoid any mix-ups.
We can also provide product catalogs or technical datasheets if you want to double-check the specifications yourself before buying. Just let us know, and we’ll get those to you.
Generally, we don’t have a strict minimum order for our standard parts — you can even order just one piece if that’s all you need. We know remanufacturing shops sometimes want to test a part’s quality first, so small sample orders are totally fine with us.
If you’re looking to buy in bulk, we can certainly discuss volume discounts. The only time we might have a minimum order is if it’s a very specialized or custom-made component, due to the production requirements. In those cases, we’d let you know upfront if any minimum applies.
In most situations, whether you need a single item or a large batch, we’re happy to accommodate. We pride ourselves on being flexible and building long-term relationships with our clients.
We offer a standard 12-month warranty on all our turbocharger spare parts. The clock starts from the date we ship them out, unless we’ve made a different agreement (for example, starting from the installation date in some cases). In short, if any part fails due to a manufacturing defect within those 12 months, it’s covered under our warranty.
If you do encounter a problem that you believe is our fault within the warranty period, just let us know. We’ll typically ask for some details about what happened (maybe a report or photos) so we can understand the issue. Once we’ve confirmed it’s a warranty case, we’ll send you a replacement part or offer you a full refund/credit for that item. We stand behind our products, so if there’s a genuine quality problem, we’ll make it right as quickly as possible.
Our warranty covers failures that result from defects in our parts (materials or workmanship) under normal use. For example, if a compressor wheel had a casting flaw or a cartridge assembly wasn’t balanced properly at the factory and it causes a premature failure, that’s on us and would be covered.
However, there are some situations that are not covered by our warranty. Here are the main exclusions:
In essence, if a part fails because it had a defect, it’s covered. But if it fails due to misuse, external factors, or normal wear, it’s not. If you ever need to claim warranty, we’ll review what happened (often via photos or a failure report) and may examine the part. That ensures we handle claims fairly and transparently.
We will arrange for a specialist to contact you immediately.
