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 rely on advanced emission components to meet environmental standards and stay on the road without interruptions. The Cummins B6.7 SCR 2018–2024: OEM 5418484 is a vital part of the Selective Catalytic Reduction (SCR) system that helps reduce harmful nitrogen oxides (NOx) from your exhaust. Knowing how this SCR unit functions and why it matters can help you maintain compliance and keep your vehicle’s emission system running smoothly.

  • Designed for Cummins B6.7 engines from 2018 through 2024, the OEM 5418484 SCR unit fits directly into your emission aftertreatment setup for a precise, worry-free installation.

  • SCR (Selective Catalytic Reduction) technology reduces NOx by injecting diesel exhaust fluid (DEF) into the hot exhaust stream, where a chemical reaction converts NOx into benign nitrogen and water vapor.

  • The OEM 5418484 SCR ensures proper compatibility with your engine’s control system, reducing the risk of diagnostic trouble codes or emission fault warnings that can occur with ill-fitting or inferior components.

  • A fully functioning SCR module helps maintain accurate DEF dosing, which supports efficient operation of the emission system and minimizes wasted fluid.

  • By replacing worn or failing SCR parts with the correct OEM unit, you help your truck avoid emission system alerts, potential engine derates, and costly downtime.

  • Manufactured to Cummins’ exact standards, this SCR module stands up to the heat, vibration, and conditions common in everyday highway and regional trucking.

  • Easy installation makes it practical for maintenance teams and service professionals during scheduled emission system servicing or repairs.

  • Using the right SCR unit contributes to your truck’s ability to meet regulatory requirements and supports cleaner exhaust output for everyday operation.

Choosing the Cummins B6.7 SCR 2018–2024: OEM 5418484 from Tamerx Diesel Parts gives you confidence that your emission control system is equipped with a quality part engineered for your engine’s specific needs. Proper SCR maintenance not only helps you stay emission-compliant but also supports dependable performance and peace of mind on every mile.

The Selective Catalytic Reduction (SCR) system is carefully monitored by your vehicle’s onboard diagnostics to ensure proper emissions control. When something goes wrong, the system will alert you through dashboard warning lights or messages. Recognizing these indicators early can help prevent reduced engine power, emissions failures, and costly repairs.

  • The check engine light is one of the most common indicators of an SCR-related issue. Faults involving DEF dosing, NOx sensors, or catalyst efficiency can trigger this warning.

  • An SCR warning light or message may appear on vehicles equipped with a dedicated emissions alert. This often points directly to a malfunction within the SCR system.

  • A DEF warning light can signal low fluid levels, contaminated DEF, or incorrect fluid quality, all of which can affect SCR performance.

  • A countdown message or “engine restart limited” alert may appear if the system detects a serious fault that has not been corrected.

  • In some cases, a reduced power or derate warning will activate, indicating the vehicle has limited performance due to an unresolved emissions issue.

If any of these warning lights appear, it’s important to have the vehicle diagnosed as soon as possible. Addressing SCR-related problems promptly helps maintain emissions compliance, prevent further aftertreatment damage, and keep your diesel engine operating reliably.

By lowering NOx emissions, the Cummins B6.7 SCR 2018-2024: OEM 5418484 helps the vehicle meet strict environmental regulations. Consistent SCR performance is key to staying within legal exhaust limits.

Regular inspection can catch buildup, clogging, or sensor faults before they lead to bigger problems with the Cummins B6.7 SCR 2018-2024: OEM 5418484. Early detection helps prevent costly repairs and unexpected failures.

A restricted Cummins B6.7 SCR 2018-2024: OEM 5418484 can hinder exhaust flow and reduce emissions treatment efficiency. This situation often results in warning codes and diminished overall performance.

Yes, problems with the Cummins B6.7 SCR 2018-2024: OEM 5418484 can trigger the engine control system to reduce power output. This protective derate helps prevent further emissions system issues until the fault is resolved.
