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 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, 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 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.

The effectiveness of a diesel SCR system depends on the condition of the catalyst surfaces that interact with exhaust gases. The Cummins QSK SCR Outlet Catalyst Module 2018-2024: OEM 5574972 provides a specialized catalyst structure that supports nitrogen oxide (NOx) reduction, helping maintain proper exhaust treatment as gases travel through the aftertreatment system.

  • OEM 5574972 is intended for compatible 2018-2024 Cummins QSK diesel applications.

  • Active catalyst surfaces provide the reaction sites needed to convert nitrogen oxides into nitrogen and water vapor.

  • Specialized catalyst coating promotes the chemical reactions involved in selective catalytic reduction.

  • Extensive internal surface area allows exhaust gases to interact with the catalyst throughout the module.

  • Contamination-resistant operation depends on maintaining clean catalyst passages and limiting deposits that could interfere with chemical reactions.

  • Flow-through substrate structure allows exhaust gases to pass through the catalyst without trapping soot like a diesel particulate filter.

  • Heat-resistant catalyst materials withstand elevated exhaust temperatures and repeated thermal changes.

  • Protective outer housing helps safeguard the internal catalyst structure against vibration and physical damage.

  • Application-specific dimensions and connections help maintain proper installation within compatible Cummins QSK aftertreatment systems.

The Cummins QSK SCR Outlet Catalyst Module OEM 5574972 provides the active catalyst structure needed for effective NOx treatment within the diesel exhaust system. Customers searching for a Cummins QSK SCR outlet catalyst, QSK SCR catalyst module, diesel SCR catalyst replacement, Cummins NOx reduction catalyst, or OEM 5574972 can find this application-specific component at TamerX Diesel Parts for compatible 2018-2024 applications.

Uneven exhaust flow through an SCR Outlet Catalyst Module can occur when internal deposits, physical damage, or problems with connected exhaust components disrupt the normal distribution of exhaust gases. Since the Selective Catalytic Reduction (SCR) system relies on consistent exhaust flow and proper contact with catalyst surfaces to reduce nitrogen oxide (NOx) emissions, irregular flow can affect aftertreatment efficiency and contribute to emissions system problems.

  • Internal deposit buildup: Excessive soot, ash, or other contaminants can accumulate inside the catalyst and create localized restrictions that interfere with exhaust distribution.

  • DEF crystallization: Improper Diesel Exhaust Fluid (DEF) dosing, poor mixing, or unsuitable operating conditions can cause deposits to form and obstruct portions of the exhaust passage.

  • Damaged catalyst substrate: Cracked, collapsed, or displaced internal catalyst material can restrict certain flow paths and cause exhaust gases to move unevenly through the module.

  • Exhaust pipe misalignment: Improperly installed or damaged exhaust connections can disrupt the flow of gases entering the SCR Outlet Catalyst Module.

  • Contamination from engine problems: Excessive oil consumption, coolant leaks, or abnormal combustion conditions can introduce deposits that interfere with catalyst passages.

  • Upstream exhaust restrictions: Problems in connected aftertreatment components may alter exhaust pressure and flow conditions, affecting how gases enter the catalyst.

  • Internal component deterioration: Prolonged exposure to excessive temperatures, vibration, or mechanical stress can damage internal structures and contribute to irregular exhaust distribution.

Uneven exhaust flow can reduce effective catalyst utilization and contribute to exhaust restrictions, SCR efficiency faults, or recurring aftertreatment warnings. Inspecting the catalyst substrate, checking for DEF deposits, and evaluating upstream exhaust components can help identify the source of the restriction and determine whether cleaning, repair, or replacement is necessary.

Consistent exhaust flow helps distribute gases across the catalyst's internal surfaces. Abnormal flow patterns may reduce contact between exhaust gases and active catalyst material, affecting overall NOx conversion.

Chemical deactivation can occur when contaminants accumulate on or react with the catalyst's active surfaces. Exposure to certain fuel, oil, or exhaust contaminants may interfere with the reactions required for effective NOx reduction.

Excessive Diesel Exhaust Fluid (DEF) injection can create more ammonia than the SCR system requires. Depending on operating conditions, this may contribute to ammonia slip, deposit formation, or abnormal aftertreatment readings.

Heavy-load operation increases exhaust flow and may change NOx production and exhaust temperatures. If the SCR system cannot maintain the required emissions performance, the engine control system may activate warnings or operating restrictions.
