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 diesel truck’s emission control system functioning properly is more important than ever, especially with today’s strict environmental standards. The Cummins B6.7 SCR 2022–2024: OEM 5418550 is a critical component that helps manage and reduce harmful nitrogen oxides (NOx) in your exhaust, ensuring your vehicle stays compliant and operates efficiently. Understanding how this SCR unit works can help you make smarter maintenance and replacement decisions for your fleet or single truck.

  • Designed specifically for Cummins B6.7 engines from 2022 to 2024, the OEM 5418550 Selective Catalytic Reduction (SCR) unit fits seamlessly into your truck’s emission system.

  • The SCR system works by injecting diesel exhaust fluid (DEF) into the exhaust stream, where it mixes and reacts to convert NOx into harmless nitrogen and water vapor.

  • Installation of a genuine OEM 5418550 SCR unit ensures proper compatibility and avoids the fitment issues that can arise with non-OEM parts.

  • A well-maintained SCR filter and catalyst help reduce the risk of emission faults, engine derates, and unnecessary diagnostic trouble codes that can lead to downtime.

  • Using the correct SCR component supports consistent DEF consumption and proper DEF dosing, helping you avoid wasted fluid and unexpected service alerts.

  • Built to Cummins’ factory specifications, this SCR unit delivers durability and reliability in the face of high heat, vibration, and heavy-duty operating conditions common in long-haul and regional trucking.

  • Replacing worn or faulty SCR components with the Cummins B6.7 SCR 2022–2024: OEM 5418550 can help extend the life of your emission system and maintain regulatory compliance.

Choosing the Cummins B6.7 SCR 2022–2024: OEM 5418550 from Tamerx Diesel Parts means investing in an emission solution designed for your engine’s exact needs. Proper SCR maintenance not only keeps your truck running cleaner but also supports dependable operation day after day, giving you peace of mind and helping protect the environment while on the road.

The Selective Catalytic Reduction (SCR) system is responsible for lowering nitrogen oxide (NOx) emissions in modern diesel engines by using Diesel Exhaust Fluid (DEF). When the SCR system begins to fail, it often gives several warning signs before complete malfunction. Recognizing these symptoms early can help prevent reduced power, failed emissions tests, and costly repairs.

  • One of the most common symptoms is an illuminated check engine light or SCR warning message on the dashboard. The system continuously monitors sensors and DEF dosing, and any irregularity can trigger a fault code.

  • Reduced engine power or derate mode may occur if the issue is not corrected. Many vehicles are programmed to limit speed or performance when emissions systems are not functioning properly.

  • Increased DEF consumption can signal improper dosing or a malfunctioning injector. In some cases, drivers may also see messages related to low DEF quality.

  • Failed emissions testing is another indicator. A faulty SCR system cannot properly reduce NOx emissions, which may result in non-compliance.

  • Rough engine operation or decreased fuel efficiency may also appear if related components such as NOx sensors or DEF injectors are not working correctly.

  • Persistent fault codes related to NOx sensors, temperature sensors, or catalyst efficiency often point directly to SCR system problems.

If you notice any of these symptoms, it’s important to have the vehicle diagnosed promptly. Addressing SCR issues early helps maintain emissions compliance, prevent further exhaust system damage, and keep your diesel engine operating reliably.

When the Cummins B6.7 SCR 2022-2024: OEM 5418550 isn’t functioning correctly, NOx levels in the exhaust may be higher than normal. This can result in increased emissions and failed compliance tests.

Ignoring problems with the Cummins B6.7 SCR 2022-2024: OEM 5418550 can lead to ongoing faults and reduced reliability. Prompt attention helps maintain emissions control and minimizes downtime.

Professional installation ensures that sensors and connections for the Cummins B6.7 SCR 2022-2024: OEM 5418550 are properly aligned. Correct setup minimizes the risk of misreads and diagnostic errors.

A malfunction with the Cummins B6.7 SCR 2022-2024: OEM 5418550 may indirectly impact engine efficiency. Poor exhaust treatment can contribute to less optimal combustion and fuel usage.
