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.

Modern diesel trucks depend on advanced aftertreatment components to meet strict emission standards and ensure reliable everyday operation. The Cummins B6.7 SCR 2022–2024: OEM 5418144 is a core part of the Selective Catalytic Reduction (SCR) system, designed to reduce nitrogen oxides (NOx) in exhaust. Knowing why this SCR unit matters and how it supports clean diesel operation can help you make smarter maintenance and replacement decisions.

  • Engineered specifically for Cummins B6.7 engines from 2022 to 2024, the OEM 5418144 SCR unit integrates directly into your emission control system for accurate and dependable fitment.

  • The SCR (Selective Catalytic Reduction) process reduces harmful NOx by injecting diesel exhaust fluid (DEF) into the exhaust stream, triggering a conversion to harmless nitrogen and water vapor.

  • Choosing the genuine OEM 5418144 SCR ensures compatibility with your engine management system, helping prevent diagnostic trouble codes and reducing the risk of emission-related warning lights.

  • A properly functioning SCR unit supports precise DEF dosing, contributing to consistent NOx reduction and helping avoid wasteful DEF consumption.

  • Replacing worn or failing SCR components with the correct OEM part can reduce the likelihood of service interruptions or emission system faults that lead to downtime.

  • Manufactured to Cummins’ strict standards, this SCR module offers the durability needed to withstand the high heat and vibration typical of daily highway or regional trucking conditions.

  • Installation is straightforward for technicians and maintenance crews, making it a practical choice when servicing emission system components during routine maintenance.

  • Using the correct SCR unit plays a key role in helping your vehicle stay compliant with environmental regulations and maintaining a cleaner exhaust output.

Choosing the Cummins B6.7 SCR 2022–2024: OEM 5418144 from Tamerx Diesel Parts gives you confidence that your truck’s emission system is equipped with a quality, engine-specific component. Proper SCR maintenance and timely replacement with genuine OEM parts help support dependable operation, reduce emission issues, and keep your vehicle ready for the road ahead.

The Selective Catalytic Reduction (SCR) system is built to withstand high exhaust temperatures and continuous operation. Its internal catalyst is designed to convert nitrogen oxide (NOx) into less harmful emissions using Diesel Exhaust Fluid (DEF). However, certain conditions can cause internal damage that reduces efficiency or leads to complete failure. Understanding what harms the SCR internally can help prevent premature replacement.

  • Oil contamination is one of the leading causes of internal damage. Excessive oil consumption or turbo-related issues can allow oil to enter the exhaust system, coating and degrading the catalyst material.

  • Coolant leaks within the engine can introduce harmful deposits into the exhaust stream. When coolant passes through the SCR, it can leave behind residue that permanently damages the catalyst.

  • Poor-quality or contaminated DEF may introduce impurities that interfere with the chemical reaction inside the SCR.

  • Excessive soot from unresolved Diesel Particulate Filter (DPF) issues can overload the system and restrict proper exhaust flow.

  • Overheating caused by improper regeneration cycles or exhaust restrictions can break down the catalyst substrate internally.

  • Physical impact or severe vibration may crack the internal substrate, reducing efficiency and triggering fault codes.

Internal SCR damage often results in reduced emissions efficiency, warning lights, and possible engine derate. Promptly addressing engine leaks, maintaining proper DEF quality, and keeping the entire aftertreatment system in good condition can help extend the life of the SCR and prevent costly repairs.

Regular checks of the Cummins B6.7 SCR 2022-2024: OEM 5418144 can catch buildup, clogging, or sensor issues before they become serious. Early detection helps prevent unexpected failures and costly repairs.

A restricted Cummins B6.7 SCR 2022-2024: OEM 5418144 can impede exhaust flow and reduce emissions treatment efficiency. This often leads to warning codes and degrading performance.

The Cummins B6.7 SCR 2022-2024: OEM 5418144 works with DEF dosing modules and exhaust sensors to monitor and adjust NOx levels. Accurate sensor feedback helps ensure effective emissions control.

Yes, problems with the Cummins B6.7 SCR 2022-2024: OEM 5418144 can cause the engine control system to limit power output for protection. This derate helps prevent further emissions system damage until the issue is resolved.
