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.

Keeping your truck’s emission system functioning as intended is vital for meeting today’s environmental regulations and avoiding costly diagnostic issues. The Cummins B6.7 SCR 2022–2024: OEM 5418581 is a key Selective Catalytic Reduction (SCR) component engineered for Cummins B6.7 engines, designed to reduce harmful nitrogen oxides (NOx) in exhaust. Understanding how this SCR unit supports clean diesel operation will help you make smart maintenance choices.

  • Designed for Cummins B6.7 engines from 2022 to 2024, the OEM 5418581 SCR unit integrates directly into the emission aftertreatment system for precise fit and function.

  • The SCR (Selective Catalytic Reduction) process works by introducing diesel exhaust fluid (DEF) into the exhaust stream, where it reacts to convert NOx into harmless nitrogen and water vapor.

  • Choosing the genuine OEM 5418581 SCR ensures compatibility with your engine’s control system, helping reduce the risk of emission-related fault codes and service warnings.

  • A properly working SCR helps maintain accurate DEF dosing, which supports effective NOx reduction and prevents unnecessary DEF loss.

  • Replacing aging or faulty SCR components with the correct OEM part helps avoid emission inspection failures and unexpected emission system alerts that can lead to downtime.

  • Built to Cummins’ exact standards, this SCR module offers durability to withstand the heat and vibration typical of everyday highway and regional trucking conditions.

  • Installation is straightforward for technicians and maintenance teams, making it practical to service during scheduled emission system checks.

  • Using the right SCR unit helps your truck stay compliant with emission regulations, supporting cleaner exhaust output and reliable daily operation.

Choosing the Cummins B6.7 SCR 2022–2024: OEM 5418581 from Tamerx Diesel Parts means equipping your truck with a quality emission control component designed specifically for your engine. Proper SCR maintenance and timely replacement with genuine OEM parts help ensure your truck operates cleanly, stays compliant, and remains dependable mile after mile.

The Selective Catalytic Reduction (SCR) system is built to operate under high exhaust temperatures while reducing nitrogen oxide (NOx) emissions. Under normal conditions, it functions within a controlled temperature range designed for proper chemical reactions with Diesel Exhaust Fluid (DEF). However, certain issues can cause the SCR system to overheat, potentially leading to reduced efficiency or internal damage.

  • Excessive exhaust temperatures caused by engine problems, such as overfueling or injector issues, can push the SCR beyond its normal operating range.

  • Failed or incomplete Diesel Particulate Filter (DPF) regeneration cycles may raise exhaust temperatures for extended periods, placing added stress on the SCR.

  • Improper DEF dosing can disrupt the chemical balance inside the catalyst, sometimes contributing to abnormal heat levels.

  • Restricted exhaust flow due to blockages or buildup can trap heat within the aftertreatment system.

  • Faulty temperature sensors may prevent the system from properly regulating exhaust heat, increasing the risk of overheating.

If the SCR overheats, it may trigger warning lights, catalyst efficiency codes, or even engine derate conditions. Prompt diagnosis of temperature-related faults and maintaining proper engine and aftertreatment performance can help prevent overheating and extend the lifespan of the SCR system.

Emissions fault codes, warning lights, or reduced engine responsiveness can indicate issues with the Cummins B6.7 SCR 2022-2024: OEM 5418581. Unusual exhaust odors or persistent DEF system alerts may also signal a problem.

The Cummins B6.7 SCR 2022-2024: OEM 5418581 actively lowers NOx levels in the exhaust to help the vehicle meet strict emissions standards. Consistent SCR performance is crucial for regulated exhaust output.

Routine inspections can catch early signs of buildup, clogged passages, or sensor issues before they cause bigger problems. Early detection helps prevent costly breakdowns and keeps the exhaust system working efficiently.

A restricted Cummins B6.7 SCR 2022-2024: OEM 5418581 can impede exhaust flow and reduce emissions control efficiency. This often triggers diagnostic warnings and affects overall system performance.
