The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.
Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.
Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".
If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue.

As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.
What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.
The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

The Detroit DD15 Turbo Assembly (OEM 4720902780) is a key component that directly influences how the engine manages airflow and combustion. Designed for 2019–2026 models, it plays a central role in ensuring the engine operates efficiently across varying conditions.
At a basic level, the turbo assembly uses exhaust gases to drive a turbine, which then forces additional air into the engine. This process allows for better air intake management and more complete combustion inside the cylinders.
Here’s why this component is so important:
- Improves air intake into the engine
- The turbo increases the amount of air entering the combustion chamber, allowing for a more controlled and efficient burn process.
- Supports consistent engine operation under load
- It helps the engine handle demanding conditions by maintaining proper airflow, especially during heavy-duty use.
- Works in coordination with fuel delivery systems
- By balancing airflow with fuel input, the turbo ensures the engine operates smoothly across different speeds and workloads.
- Contributes to cleaner exhaust output
- Proper air management helps reduce unburned fuel in the exhaust, supporting emissions system effectiveness.
- Adapts to changing driving conditions
- The turbo responds dynamically to throttle input and engine demand, adjusting airflow in real time.
- Supports overall engine reliability
- When functioning correctly, it helps reduce strain on internal components by maintaining proper combustion conditions.
In simple terms, the Detroit 4720902780 turbo assembly acts as the engine’s airflow regulator, helping maintain balance between air and fuel while supporting smooth and reliable operation.
A failing turbo assembly can lead to noticeable changes in how your engine behaves. Since the turbo is responsible for managing airflow and boosting efficiency, any issue within the assembly can quickly affect overall operation.
Recognizing the early warning signs can help prevent further damage and more expensive repairs down the line.
Here are common signs that your turbo assembly may be failing:
- Loss of acceleration or power
- If the turbo isn’t supplying the proper airflow, the engine may feel sluggish, especially when accelerating or climbing.
- Excessive exhaust smoke
- Blue, black, or white smoke can indicate oil leaks or improper air-fuel balance caused by turbo issues.
- Unusual whining or grinding noises
- High-pitched whining or metallic sounds may point to worn internal components or bearing failure within the turbo.
- Check engine light or boost-related fault codes
- The system may detect irregular boost levels and trigger warning lights or diagnostic codes.
- Oil leaks around the turbo area
- Damaged seals can allow oil to escape, which may also lead to internal contamination.
- Inconsistent boost pressure
- Fluctuating or weak boost levels can signal problems with the turbo or related components.
Addressing these signs early can help avoid further damage to the engine and ensure the turbo system continues to function properly.
Typical signs include unusual noises, excessive exhaust smoke, oil leakage around the turbo, and fault codes related to airflow or turbo operation.
The assembly typically includes the turbine housing, compressor housing, center housing rotating assembly (CHRA), and an electronic actuator depending on configuration.
By controlling exhaust flow and pressure, it helps maintain proper conditions for emissions-related components such as EGR and aftertreatment systems to function correctly.
Yes, it is built to OEM specifications, ensuring proper fitment, correct mounting points, and compatibility with DD15 engine systems.
