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.

Controlling nitrogen oxide (NOx) emissions is a major requirement in modern diesel engines, and the Cummins L9 SCR OEM 5508188 plays a central role in achieving that goal. Designed for 2022–2024 Cummins L9 applications, this Selective Catalytic Reduction (SCR) unit is responsible for reducing NOx levels in the exhaust stream.

The primary role of the SCR system is to convert harmful NOx gases into harmless nitrogen and water vapor before the exhaust exits the vehicle or equipment.

The Cummins L9 SCR OEM 5508188 is responsible for:

  • Supporting NOx reduction within the exhaust system
  • Housing the catalyst substrate where chemical reactions occur
  • Working in coordination with the DEF dosing system
  • Maintaining proper exhaust flow
  • Assisting in emissions compliance

The SCR process works by injecting Diesel Exhaust Fluid (DEF) upstream into the exhaust stream. Heat converts the DEF into ammonia. As exhaust gases pass through the SCR catalyst, ammonia reacts with NOx and converts it into nitrogen and water vapor.

The engine control module (ECM) monitors NOx sensors and temperature sensors to regulate DEF dosing accurately. This ensures efficient NOx conversion without excessive fluid use.

Engineered specifically for Cummins L9 engines, the OEM 5508188 SCR unit ensures proper fitment and compatibility with factory aftertreatment components.

When functioning correctly, it plays a critical role in maintaining clean exhaust output, regulatory compliance, and dependable engine operation.

The SCR (Selective Catalytic Reduction) system reduces NOx emissions by injecting Diesel Exhaust Fluid (DEF) into the exhaust stream. Because it relies on precise chemical reactions and proper exhaust temperatures, consistent maintenance is essential to extend its lifespan.

Clean DEF and proper engine operation are critical.

To help prolong the lifespan of your SCR system:

  • Use fresh DEF that meets ISO 22241 standards
  • Store DEF in sealed containers away from extreme temperatures
  • Avoid contaminated or expired DEF
  • Address SCR or check engine warning lights immediately
  • Repair exhaust leaks promptly
  • Maintain fuel injectors and the EGR system

Contaminated DEF can create deposits that coat the catalyst surface and reduce efficiency. Over time, buildup may trigger NOx efficiency fault codes.

Engine problems that increase soot levels can also strain the SCR system. Excess soot and improper combustion affect overall aftertreatment performance.

Maintaining related components is just as important. Faulty NOx sensors or a malfunctioning DEF doser injector can cause improper dosing, which may shorten SCR life.

Routine diagnostics and early repairs help prevent small issues from becoming major failures.

With proper maintenance and prompt attention to warning signs, you can significantly extend the service life of your SCR system and protect your emissions components.
