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.

Emission systems are a critical part of modern diesel truck operation, helping vehicles meet regulatory standards and reduce harmful pollutants. The Cummins L9 SCR 2022–2024: OEM 5507873 is a core Selective Catalytic Reduction (SCR) component designed to lower nitrogen oxides (NOx) in exhaust gas. Focusing on how this SCR unit supports effective emission control can help truck owners and service teams make smart maintenance decisions.

  • Designed for Cummins L9 engines from 2022 to 2024, the OEM 5507873 SCR unit integrates precisely into the emission aftertreatment system for accurate fit and function.

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

  • Installing the genuine OEM 5507873 SCR ensures proper compatibility with your engine’s emission control strategy, helping minimize diagnostic trouble codes and emission warning lights.

  • A properly operating SCR supports accurate DEF dosing, which contributes to efficient NOx reduction and helps prevent unnecessary DEF waste.

  • Choosing the correct SCR component reduces the risk of service interruptions related to emission system faults or sensor miscommunication that can affect daily truck operation.

  • Effective SCR performance enhances communication between emission sensors and the engine control module, leading to fewer false fault signals and smoother system response.

  • Built to Cummins’ original standards, this SCR module offers durability to withstand heat, vibration, and the demanding conditions typical of highway and regional use.

  • Installation is straightforward for professional technicians and fleet maintenance teams during routine emission system servicing or part replacement intervals.

Choosing the Cummins L9 SCR 2022–2024: OEM 5507873 from Tamerx Diesel Parts gives you confidence that your emission control system is equipped with a quality, engine-specific component. With reliable SCR function and proper upkeep, your truck will continue to meet emission standards and remain dependable on every mile.

The Selective Catalytic Reduction (SCR) system is carefully monitored by your vehicle’s onboard diagnostics to ensure proper emissions control. When something goes wrong, the system will alert you through dashboard warning lights or messages. Recognizing these indicators early can help prevent reduced engine power, emissions failures, and costly repairs.

  • The check engine light is one of the most common indicators of an SCR-related issue. Faults involving DEF dosing, NOx sensors, or catalyst efficiency can trigger this warning.

  • An SCR warning light or message may appear on vehicles equipped with a dedicated emissions alert. This often points directly to a malfunction within the SCR system.

  • A DEF warning light can signal low fluid levels, contaminated DEF, or incorrect fluid quality, all of which can affect SCR performance.

  • A countdown message or “engine restart limited” alert may appear if the system detects a serious fault that has not been corrected.

  • In some cases, a reduced power or derate warning will activate, indicating the vehicle has limited performance due to an unresolved emissions issue.

If any of these warning lights appear, it’s important to have the vehicle diagnosed as soon as possible. Addressing SCR-related problems promptly helps maintain emissions compliance, prevent further aftertreatment damage, and keep your diesel engine operating reliably.

While the Cummins L9 SCR 2022-2024: OEM 5507873 itself doesn’t need frequent hands-on maintenance, checking DEF quality, sensor integrity, and system warnings is critical. Regular checks help catch issues before they cause major faults.

Yes — inefficient SCR performance or sensor problems can lead to higher than normal DEF use. Monitoring DEF usage trends can help identify when the Cummins L9 SCR 2022-2024: OEM 5507873 might need inspection.

A healthy Cummins L9 SCR 2022-2024: OEM 5507873 supports smooth engine operation by preventing emissions system derates. If the SCR malfunctions, the engine management system may reduce power to protect emissions compliance.

Extremely cold weather can temporarily impact DEF quality and flow, while high heat can affect system conditions. Monitoring DEF and system warnings helps maintain proper SCR performance regardless of climate.
