What types of turbocharger spare parts do you offer?

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: CHRA (Core Assemblies): Complete cartridge core units for various turbo models. Turbine Wheels & Shafts: Turbine wheel-and-shaft assemblies available in different sizes and materials. Compressor Wheels: High-precision compressor wheels made from durable high-strength alloys (aluminum or even titanium, depending on the application). Bearing & Seal Kits: Overhaul kits with journal bearings, thrust bearings, seals, and rings for rebuilding turbos. Actuators & Components: Wastegate actuators (mechanical) and electronic actuators, plus related small parts. 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.

How can I ensure I choose the correct part for my turbocharger?

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.

Is there a minimum order quantity, or can I order samples for testing?

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.

What is the warranty on your turbocharger spare parts?

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.

What does the warranty cover and what are the exclusions?

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: Improper Installation or Misuse: If the part was installed incorrectly or used incorrectly — e.g. not priming the turbo with oil before startup, wrong gaskets, misassembly. External Factors (Oil Starvation or Contamination): Failures caused by inadequate or dirty oil (e.g. blocked feed lines or poor oil quality). Foreign Object Damage: Debris entering the turbo (intake or exhaust) and damaging parts. Operating Outside Design Limits: Engine or turbo run beyond design parameters (overspeed, excessive exhaust temperatures, etc.). Normal Wear and Tear: Gradual wear of consumables (e.g. seals) under regular usage. 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.

In the global automotive and industrial sectors, performance is defined by precision. Our mission is to provide the global market with Premium Aftermarket Turbochargers and high-precision components that serve as a seamless, high-performance alternative to original units. While we are an independent manufacturer, our products are engineered with one primary objective: to provide a perfect fit and identical (or superior) performance to original equipment from the world’s leading brands.

Whether you are maintaining a luxury passenger sedan, a light-commercial delivery fleet, or heavy-duty industrial machinery, our solutions offer the ideal balance between OEM-level reliability and aftermarket cost-efficiency. Our components are designed to be 100% interchangeable with major turbocharger manufacturers, including Garrett, BorgWarner (KKK & Schwitzer), Holset (Cummins), IHI, Mitsubishi (MHI), and Toyota.

⚡ Why Choose Our Aftermarket Solutions?

Perfect Interchangeability: Every housing, wheel, and bolt is mapped to original dimensions. This ensures a “Plug-and-Play” installation experience for technicians working on Volkswagen, Ford, BMW, Cummins, or Caterpillar engines.
Advanced Aerodynamic Response: We don’t just copy; we optimize. By using modern computational fluid dynamics (CFD), our aftermarket units often provide a faster spool-up and broader torque curve than the aging OEM designs they replace.
Maximum Thermal Resilience: Our units are built for the long haul. We utilize premium alloys that maintain structural integrity under the extreme heat typical of Mercedes-Benz, Audi, and Volvo exhaust systems, preventing premature cracking and failure.

II. Brand Compatibility: Seamless Integration with Global Leaders

We specialize in the meticulous engineering of components that integrate perfectly into existing engine systems. We provide a comprehensive catalog that supports the world’s most trusted turbocharger platforms.

III. Manufacturing Excellence: The Science of High-Precision Aftermarket

The term “Aftermarket” should never mean “Lower Quality.” Our ISO-certified facility utilizes a “Zero-Tolerance” manufacturing philosophy to ensure our parts match the performance maps of the original brands.

1. The Multi-Stage VSR Balancing Workflow

A turbocharger rotating at 200,000+ RPM is a masterpiece of balance. We eliminate vibration—the primary cause of aftermarket turbo failure—through a rigorous three-tiered process:

Component Balancing: Individual turbine shafts and compressor wheels are statically and dynamically balanced to micron-level tolerances.
Core Assembly Alignment: The assembled CHRA (Central Housing Rotating Assembly) is low-speed balanced to ensure all internal components are perfectly centered.
VSR (Vibration Sorting Rig) Testing: This is the ultimate verification. Our VSR machines accelerate the assembled core to actual operating speeds under hot, pressurized oil. We calibrate the unit until the residual vibration is below $0.5 text{mg}$ . This ensures that our aftermarket unit operates as silently and reliably as a Garrett or BorgWarner original.

2. Advanced Material Specifications

We utilize premium materials that meet or exceed the metallurgical requirements of the original brands:

Turbine Wheels: Crafted from Inconel 713C superalloys. This material retains its “creep strength” at temperatures over $850^circtext{C}$ , essential for the high-thermal loads of a Scania or Mack engine.
Compressor Wheels: We offer high-grade cast aluminum and MFS (Machined from Solid) Billet Aluminum. Billet wheels are forged for superior density, making them a preferred aftermarket upgrade for high-boost applications in Subaru or Mitsubishi performance vehicles.
Bearing Systems: Our journal and thrust bearings are machined from specialized high-lead bronze, providing a robust sacrificial surface that protects the shaft during cold starts and high-speed operation.

V. Master Installation Guide: Protecting Your Aftermarket Investment

In the aftermarket world, successful installation is the key to longevity. A replacement turbocharger is only as good as the system it is installed in. We recommend the following “Gold Standard” protocol for all technicians.

1. Forensic Diagnosis: Identifying the “Why”

Before installing our replacement unit, technicians must identify the root cause of the previous failure:

Oil Starvation: Check the feed lines. Modern BMW and PSA engines are notorious for carbon-clogged feed pipes that starve the turbo.
Oil Contamination: If the engine oil is dirty, it will act like liquid sandpaper on the new bearings.
Foreign Object Damage (FOD): Even a tiny piece of an old air filter will destroy a compressor wheel instantly.
Excessive Backpressure: A blocked DPF (Diesel Particulate Filter) can melt the turbine wheel of a Cummins or Volvo turbo within hours.

2. Professional Installation Workflow

System Hygiene: Always replace the engine oil, oil filter, and air filter. Crucially, replace the turbo oil feed line. Attempting to clean an old feed line is the most common mistake in aftermarket repairs.
Intercooler Cleaning: If the previous turbo suffered a catastrophic mechanical failure, the intercooler must be solvent-cleaned or replaced to remove metal shards.
The “Oil Priming” Rule: Never start a dry turbo. Fill the center housing with clean oil and spin the wheel by hand. This ensures the bearings are floating on a film of oil before the engine reaches high RPMs.
Initial Idle: After installation, let the engine idle for 5–10 minutes. This allows oil pressure to stabilize and ensures the sealing rings are properly seated.

VI. Global Logistics, Warranty & Sustainability

1. Industry-Leading Warranty Commitment

We stand behind our aftermarket engineering with a 12-Month Unlimited Mileage Warranty. We believe that choosing an aftermarket solution shouldn’t involve a gamble. If our part fails due to a manufacturing defect in materials or workmanship, our technical team provides a transparent claim process and swift replacement.

2. Global Supply Chain Efficiency

Rapid Fulfillment: We maintain a massive inventory of components for the most popular Toyota, VW, Cummins, and Caterpillar engine models.
Logistics Flexibility: We utilize Air Express (DHL/FedEx) for urgent “Truck Down” situations (5–7 days) and Sea Freight for bulk stock replenishment (3–6 weeks).
No MOQ Policy: We support independent workshops and large distributors alike. Whether you need one seal or a container of CHRAs, we provide the same professional attention.

3. Our Commitment to the Environment

Turbocharging is inherently sustainable. By providing the high-quality parts needed to rebuild and revitalize Garrett, Holset, and BorgWarner units, we support the global remanufacturing industry. This prevents thousands of tons of raw materials from going to landfills every year by allowing original metal castings to be reused and upgraded.
