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 Cummins L9 Turbo Assembly OEM 5551213RX is a factory-specified turbocharger designed for Cummins L9 diesel engines manufactured from 2021 through 2024. It is a key component of the engine’s air induction system and is engineered to integrate seamlessly with the L9’s intake and exhaust systems.
In a diesel engine, the turbo assembly uses energy from exhaust gases to improve how much air enters the engine’s cylinders. Although this part does not add fuel or change combustion chemistry, it increases the amount of air available for combustion. This allows the engine to operate more efficiently across a wide range of speeds and loads.
Key functions of the Cummins L9 Turbo Assembly OEM 5551213RX include:
- Capturing exhaust gas energy to spin a turbine
- Driving a compressor wheel that pressurizes incoming air
- Providing higher airflow to support combustion demands
- Helping maintain stable intake airflow
- Integrating with sensors and engine controls for proper regulation
The turbocharger contains two core sections — a turbine housing on the exhaust side and a compressor housing on the intake side — connected by a shaft and supported by internal bearings. As exhaust gases pass through the turbine, the spinning motion drives the compressor wheel, which draws in ambient air and forces it into the engine at increased pressure.
The OEM 5551213RX unit is built to Cummins’ exact specifications, ensuring correct fitment, structural integrity, and reliable performance in L9 engines. When functioning properly, it helps maintain steady airflow, support combustion consistency, and contribute to dependable engine operation.
The turbo assembly operates under extreme heat and spins at very high speeds. Because it depends heavily on clean oil and proper airflow, routine maintenance plays a major role in extending its lifespan.
Protecting lubrication is the most important step.
To help prolong the lifespan of your turbo assembly:
- Follow recommended oil change intervals
- Use the correct oil grade specified by the manufacturer
- Allow the engine to idle briefly after heavy driving before shutting it off
- Avoid hard acceleration while the engine is still cold
- Replace the air filter as needed
- Inspect oil supply and return lines regularly
Clean oil is critical because the turbo’s bearings rely on constant lubrication. Dirty or degraded oil can lead to internal wear and shaft damage.
It is also important to monitor for leaks. Restricted oil flow or contamination can quickly shorten turbo life.
Maintaining the air intake system helps as well. A clogged air filter can cause the turbo to work harder than necessary.
Finally, never ignore unusual noises, smoke, or warning lights. Addressing small issues early can prevent more serious internal damage and help your turbo assembly operate reliably for many miles.
Yes, installation may require a separate compatible actuator and any necessary gaskets or hardware.
Yes, issues with the Cummins 5551213RX Turbo Assembly can trigger related diagnostic codes.
Using the correct OEM 5551213RX ensures proper fit with engine components and supported turbocharger system operation.
