When heavy-duty trucks are pushed to their limits, our replacement turbochargers excel where OEM units may fall short. Designed for rigorous heavy-duty use, these turbochargers not only restore factory-level performance but often surpass it, all while maintaining exceptional reliability and durability that minimizes fleet downtime.
⚡ Enhanced Responsiveness & Thermal Control: Experience improved surge response and significantly lower exhaust gas temperatures (EGTs), resulting in sharper throttle response and smoother operation even under extreme loads. This critical thermal advantage protects the engine’s valves and pistons from heat fatigue.
💰 Superior Cost-Efficiency & Value: Our aftermarket units offer comparable or even enhanced performance at a fraction of the OEM cost, drastically improving your Total Cost of Ownership (TCO) and maximizing fleet profitability.
🛠️ Broad Compatibility & Simplified Procurement: Supports a wide range of heavy-duty engine models and marques, ensuring quick, accurate pairing and reducing logistics complexity associated with sourcing specialized OEM parts.
We stand by the quality of our turbochargers and components through rigorous manufacturing and testing protocols that meet or exceed industry standards.
Every central rotating component (CHRA) undergoes a multi-stage balancing process to ensure smooth operation at extremely high speeds (up to ).
Low-Speed Balancing: Corrects static and dynamic imbalances of individual components (turbine wheel, compressor wheel, shaft).
High-Speed VSR Balancing: The assembled CHRA unit is tested using Vibration Sorting Rig (VSR) equipment. This dynamic test simulates real-world operating speeds under oil pressure, ensuring residual imbalance is corrected to an industry-leading tolerance (often less than ), minimizing premature bearing wear and maximizing the turbocharger’s service life. This step is mandatory for all core assemblies.
Actuator Calibration: Electronic and mechanical actuators are pre-calibrated and tested to ensure precise boost control and optimal integration with the Engine Control Unit (ECU).
We select materials specifically engineered to withstand the harsh environment of commercial diesel applications, focusing on thermal stability and mechanical strength:
Casting Integrity: Compressor and turbine housings are made from high-grade casting alloys (like SiMo Ductile Iron for the turbine section) ensuring structural integrity under immense heat cycling and pressure variations without warping or cracking.
Sealing Technology: Utilizes high-performance piston rings and specialized journal bearings and seals to ensure optimal oil containment and prevent boost pressure leakage, even under elevated operating pressures.
Aero-Dynamics: Compressor wheels often utilize Billet (forged) construction, allowing for thinner, more aggressive blade designs that reduce rotational inertia and improve airflow compared to traditional cast wheels.
We provide a comprehensive range of turbocharger spare parts to support both remanufacturing and repairs. Our product lineup includes virtually everything you might need:
Preventing premature failure is key. We strongly recommend adhering to the following best practices during installation. Adherence to this guidance is vital for maintaining warranty validity.
Identify the Root Cause (Forensic Diagnosis): Always determine why the original turbo failed. A new turbo installed on an engine with contaminated oil, restricted oil flow, or excessive exhaust temperatures will fail again quickly. The root cause must be fixed.
Inspect Engine System Integrity: Clean or replace all air filters, oil feed/drain lines, intercoolers, and exhaust manifolds to eliminate debris, sludge, or blockages that could contaminate the new unit.
Oil Priming (CRITICAL STEP): Absolutely critical. Before the initial engine start, manually prime the new turbocharger with clean engine oil through the oil inlet hole and spin the wheel by hand. This prevents oil starvation during the first few seconds of operation, which is the leading cause of early bearing failure.
New Gaskets Only: Always use new gaskets and O-rings to prevent leaks and ensure proper sealing integrity and thermal expansion allowances.
By maintaining proper oil change intervals, avoiding aggressive hot shutdowns (allowing the engine to idle briefly after heavy load use to let the turbo cool), and ensuring the engine’s air and fuel systems are calibrated correctly, you will significantly extend the service life of your new turbocharger and all related engine components.
Choosing high-quality aftermarket replacement parts supports a more sustainable operational model.
Resource Efficiency & Remanufacturing Support: Our commitment to supplying robust spare parts supports the remanufacturing industry, extending the life cycle of the original turbocharger body and significantly reducing the demand for new resource extraction.
Modern Emissions Compliance: When paired with proper engine tuning, our high-efficiency components help maintain engine performance while contributing to cleaner combustion and adherence to modern emissions standards.
Standard 12-Month Warranty: We offer a standard 12-month warranty on all our turbocharger spare parts, starting from the date of shipment. This covers any part failure due to verified manufacturing defects (materials or workmanship) under normal use.
Exclusions: Warranty is voided if the failure is caused by external factors including: Oil Starvation/Contamination (dirty oil, low pressure), Foreign Object Damage (FOD), improper installation, or operating outside the engine’s design limits.
Global Logistics: We ship globally using standard Incoterms (EXW/FOB) and offer various methods including Air Express (for speed), Air Freight, and Sea Freight (for bulk economy). We strive for a 3-5 business day fulfillment time for in-stock items.
Returns: We accept returns for DOA (Defective on Arrival) and incorrect parts. All returns require prior Return Authorization from our team to ensure proper processing.

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.
