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.

For truck owners and fleet operators, maintaining a clean and compliant emission control system is more than a regulatory necessity—it’s part of ensuring smooth, trouble-free operation. The Cummins B6.7 SCR 2022–2024: OEM 5418555 is a core component in the Selective Catalytic Reduction (SCR) system that helps reduce harmful nitrogen oxides (NOx) from exhaust gas. Knowing how this SCR unit fits into your emission setup and why the correct part matters can help you avoid issues down the road.

  • Engineered specifically for Cummins B6.7 engines from 2022 to 2024, the OEM 5418555 SCR unit integrates precisely into your truck’s emission aftertreatment system.

  • Selective Catalytic Reduction works by injecting diesel exhaust fluid (DEF) into the exhaust stream, where it initiates a chemical reaction that converts NOx into harmless nitrogen and water vapor.

  • Choosing the genuine OEM 5418555 SCR ensures proper compatibility with your engine’s emission controls, reducing the chance of miscommunication between sensors and control modules.

  • A correctly functioning SCR can help stabilize DEF dosing, which supports efficient NOx reduction and helps avoid unnecessary fluid waste.

  • Replacing worn or failing SCR units with the right OEM part helps prevent emission-related fault codes, warning lights, and potential engine derates that disrupt daily operation.

  • Built to meet Cummins’ strict specifications, this SCR module offers durability against the heat and vibration that come with everyday highway and regional trucking conditions.

  • Installation is straightforward for maintenance professionals, making it a practical choice during routine emission system servicing or component updates.

  • Ensuring your SCR system functions as intended plays a key role in maintaining compliance with emission standards and supporting cleaner truck operation.

Choosing the Cummins B6.7 SCR 2022–2024: OEM 5418555 from Tamerx Diesel Parts gives you confidence that your emission control system is equipped with a quality, engine-specific component. Proper SCR selection and timely replacement help keep your truck emission-compliant, dependable, and ready for the demands of daily work.

The Selective Catalytic Reduction (SCR) system is a key component in modern diesel emissions control, using Diesel Exhaust Fluid (DEF) to reduce nitrogen oxide (NOx) emissions. While the SCR catalyst itself is designed for long service life, proper maintenance is essential to keep the system operating efficiently and to prevent warning lights or derate conditions.

  • Regularly monitor and refill DEF with manufacturer-approved fluid. Running low or using contaminated DEF can trigger system faults.

  • Store DEF properly in sealed containers and avoid exposure to dirt, moisture, or extreme temperatures that could affect fluid quality.

  • Inspect and replace DEF filters, if equipped, according to the recommended service interval.

  • Check the DEF injector for crystallization buildup that could restrict proper dosing.

  • Monitor NOx sensors and temperature sensors for accurate readings, especially if diagnostic codes appear.

  • Address engine issues such as excessive oil consumption or coolant leaks promptly to prevent contamination of the SCR catalyst.

  • Ensure the Diesel Particulate Filter (DPF) is functioning properly, as upstream exhaust problems can impact SCR performance.

Routine inspections and prompt attention to warning lights are the foundation of SCR maintenance. By maintaining proper DEF quality and keeping the entire aftertreatment system in good condition, you can help extend the life of the SCR and ensure reliable emissions control.

By lowering nitrogen oxide emissions, the Cummins B6.7 SCR 2022-2024: OEM 5418555 reduces the release of harmful pollutants. This helps decrease the vehicle’s environmental footprint.

Ignoring SCR faults can lead to recurring warning codes and reduced reliability. Prompt repairs help maintain stable emissions performance and minimize downtime.

A malfunctioning Cummins B6.7 SCR 2022-2024: OEM 5418555 can disrupt optimal exhaust flow and combustion balance. This may result in slightly increased fuel consumption.

Regular inspection helps detect buildup, leaks, or sensor irregularities before they escalate. Preventive maintenance supports long-term emissions system reliability.
