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.

Maintaining a clean and compliant exhaust system is essential for on-road diesel trucks — and the heart of that system is the Selective Catalytic Reduction (SCR) assembly. For Cummins B6.7 engines built between 2022 and 2024, the Cummins B6.7 SCR 2022–2024: OEM 5418144 delivers reliable emissions control and trusted compatibility with factory aftertreatment systems. Choosing the correct SCR unit helps ensure your engine meets emissions standards, avoids system faults, and supports dependable performance mile after mile.

    • The SCR assembly plays a critical role in converting nitrogen oxides (NOx) into nitrogen and water,
      helping your truck adhere to EPA emissions regulations and operate cleanly.

    • The OEM 5418144 SCR component is specifically engineered for Cummins B6.7 engines from 2022 to 2024,
      ensuring proper fit and smooth integration with the original exhaust aftertreatment system.

    • Working together with your DEF dosing system, this SCR unit supports balanced exhaust cleaning,
      which helps optimize DEF consumption and maintain efficient emissions performance.

    • Installing the correct OEM SCR part reduces the likelihood of emissions warning lights, fault codes,
      and derate events that can interrupt operation and lead to unnecessary downtime.

    • A fully functioning SCR system helps protect other aftertreatment components by minimizing excess emissions buildup,
      supporting longer service life and fewer unexpected maintenance issues.

    • Choosing an OEM-quality replacement like the Cummins B6.7 SCR 2022–2024: OEM 5418144 gives you confidence in reliability,
      durability, and consistent emissions control performance.

Selecting the right SCR component makes a real difference in the long-term health of your Cummins B6.7 emissions system. The OEM 5418144 SCR assembly helps restore effective NOx reduction and supports smooth, compliant operation for your truck. At Tamerx Diesel Parts, we offer trusted diesel components to help you reduce downtime and keep your fleet performing at its best.

A Selective Catalytic Reduction (SCR) system is a long-lasting emissions component designed to reduce nitrogen oxide levels in diesel exhaust. Built for durability, SCR catalysts typically operate for many years under normal driving conditions. However, lifespan can vary depending on maintenance habits, DEF quality, and overall exhaust system health.

  • Typical lifespan range: Many SCR systems last between 250,000 and 500,000 miles under normal conditions.

  • DEF quality is critical: Using manufacturer-approved DEF helps prevent catalyst contamination and deposits.

  • Upstream component health matters: Proper DOC and DPF operation reduces soot and ash reaching the SCR.

  • Driving patterns affect longevity: Regular highway driving supports the exhaust temperatures needed for SCR efficiency.

  • Sensor and dosing reliability: Working NOx sensors and DEF injectors help maintain proper catalyst function.

  • Early repair of warning signs: Prompt diagnostics prevent minor issues from shortening SCR life.

An SCR system is designed for long-term service, but poor DEF management or unresolved upstream problems can reduce its lifespan. Consistent maintenance and early attention to faults help maximize SCR durability and ensure reliable emissions control.

While the SCR’s main role is emissions control, it helps maintain proper exhaust flow and prevents derate events that can negatively affect fuel economy. A healthy aftertreatment system supports consistent combustion efficiency.

Yes — a malfunctioning SCR unit often triggers emissions-related alert lights, including check engine or DEF warnings. These alerts are designed to help you detect aftertreatment issues early.

By reducing NOx emissions from diesel exhaust, this SCR filter helps decrease harmful pollutants in the air. Cleaner exhaust contributes to improved air quality and reduced smog formation.

In many installations, a system reset or emissions recalibration is recommended to ensure the ECU correctly recognizes the new SCR filter. This step helps optimize performance and emissions tracking after replacement.
