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.

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.

A dependable emission control system is a must for modern diesel trucks to meet environmental standards and avoid costly service issues. The Cummins L9 SCR 2022–2024: OEM 5507872 is a Selective Catalytic Reduction (SCR) component engineered to reduce nitrogen oxides (NOx) in exhaust gases. Understanding the role this SCR unit plays in emission aftertreatment can help truck owners and maintenance teams ensure cleaner operation and long-term system health.

  • Engineered for Cummins L9 engines from 2022 to 2024, the OEM 5507872 SCR unit fits directly into the emission aftertreatment system with precise compatibility.

  • The SCR (Selective Catalytic Reduction) system works by introducing diesel exhaust fluid (DEF) into the exhaust stream, where a chemical reaction transforms NOx into harmless nitrogen and water vapor.

  • Installing the genuine OEM 5507872 SCR helps ensure proper communication between the emission system and engine control module, reducing the risk of diagnostic trouble codes or unexpected warning lights.

  • A functioning SCR supports accurate DEF dosing, which promotes efficient NOx reduction and helps avoid excessive DEF consumption associated with poorly matched components.

  • Replacing worn or underperforming SCR units with the correct OEM part helps prevent emission faults that can lead to service alerts and unplanned repair time.

  • Effective SCR performance enhances the overall reliability of the emission aftertreatment system by minimizing false error signals and improving sensor response.

  • Built to meet Cummins’ original manufacturing standards, this SCR module offers durability to withstand heat, vibration, and daily highway and regional driving conditions.

  • Installation is practical and straightforward for technicians and maintenance professionals during routine emission system service or part replacement intervals.

Choosing the Cummins L9 SCR 2022–2024: OEM 5507872 from Tamerx Diesel Parts means equipping your truck with a high-quality emission control component designed for your engine’s exact needs. With reliable SCR function and proper maintenance, your vehicle will remain emission-compliant and dependable mile after mile.

The Selective Catalytic Reduction (SCR) system plays a vital role in reducing nitrogen oxide (NOx) emissions in modern diesel engines. Over time, contamination or buildup can affect its efficiency, especially if the engine has underlying issues or improper DEF has been used. While the SCR catalyst itself is not typically “cleaned” in the traditional sense like other components, there are important steps that can help restore or maintain proper operation.

  • Start by diagnosing the system with a scan tool to identify fault codes related to NOx sensors, DEF dosing, or catalyst efficiency. Proper diagnosis ensures the issue is not sensor- or injector-related.

  • Inspect and, if necessary, clean or replace the DEF injector. Crystallized DEF can build up around the injector tip and restrict proper dosing.

  • Check for DEF contamination. If poor-quality or incorrect fluid was used, draining and refilling the DEF tank with fresh, manufacturer-approved fluid may be required.

  • Inspect upstream components such as the Diesel Particulate Filter (DPF). Excessive soot or unresolved regeneration issues can impact SCR performance.

  • In some cases, professional cleaning services can remove certain types of buildup from the SCR catalyst, but severely contaminated units may require replacement.

  • Address engine problems such as oil or coolant leaks immediately, as these contaminants can permanently damage the SCR catalyst.

Routine maintenance and proper DEF handling are the best ways to prevent SCR contamination. If warning lights or efficiency codes appear, prompt inspection and repair can help restore system function and maintain emissions compliance.

Factors like contaminated DEF, worn catalyst surfaces, or sensor failures can impair SCR performance. These issues may lead to higher NOx readings and trigger emissions warnings.

Proper installation with correct alignment and secure connections is important to ensure accurate exhaust flow and sensor readings. Following manufacturer guidelines helps avoid leaks and misreads.

The engine management system may reduce power output to protect emissions integrity when the SCR shows faults. This derate helps prevent further damage and keeps emissions under control.

It’s recommended to check emissions components like the Cummins L9 SCR 2022-2024: OEM 5507872 during regular maintenance intervals. Routine inspections help catch buildup, sensor issues, and fluid problems early.
