SHIPPING POLICY
Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Tamerx Diesel Products only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.
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. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.
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 DD8 Turbo Assembly 2017–2021: OEM EA9360901386 works by using exhaust energy to drive a turbine that compresses incoming air before it enters the engine. This process allows the engine to receive a greater volume of dense air, supporting efficient combustion across a wide range of operating conditions.
As exhaust gases exit the engine, they flow into the turbine housing of the turbocharger. The exhaust energy spins the turbine wheel, which is connected by a shaft to the compressor wheel on the intake side. As the turbine rotates, the compressor wheel draws in fresh air, compresses it, and pushes it into the engine’s intake system.
The Detroit DD8 turbo assembly typically features a variable geometry mechanism. This system adjusts the angle of internal vanes to control exhaust flow across the turbine. By changing vane position, the turbo can respond to different engine speeds and load demands, improving airflow control and supporting emissions management.
Here’s how the system functions step by step:
- Exhaust gases spin the turbine wheel
- The connected shaft drives the compressor wheel
- Fresh air is compressed and directed into the engine
- Variable vanes adjust to regulate airflow based on demand
Designed specifically for 2017–2021 Detroit DD8 engines, OEM EA9360901386 integrates with the engine control system to ensure precise airflow management, stable engine operation, and proper emissions control.
Prolonging the lifespan of your turbo assembly starts with protecting its lubrication system and preventing excessive heat or contamination. Turbochargers operate at extremely high speeds and temperatures, so even small maintenance issues can lead to premature failure.
The most critical factor is clean, consistent oil supply. The turbo depends on engine oil for both lubrication and cooling. Dirty, degraded, or restricted oil flow is the leading cause of turbo failure. Always follow recommended oil change intervals and use the correct oil specification for your engine.
Midway through routine maintenance, focus on these best practices to extend turbo life:
- Change engine oil and filters on schedule
- Inspect and replace restricted turbo oil feed and return lines
- Allow the engine to idle briefly before shutdown after heavy load
- Repair fuel injector or over-fueling issues promptly
- Monitor exhaust temperatures and regeneration performance
- Check for boost leaks in the charge air system
It is also important to maintain proper air filtration. A clogged or damaged air filter can allow debris into the compressor side of the turbo, causing blade damage and imbalance. Likewise, unresolved DPF or DOC restrictions can increase exhaust backpressure and stress the turbine side.
Most turbo failures are not random; they are caused by oil starvation, contamination, overheating, or upstream engine issues. Consistent maintenance, proper warm-up and cool-down habits, and early correction of engine faults are the most effective ways to maximize turbocharger lifespan and avoid costly repairs.
