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 emission control systems to meet regulatory standards and operate smoothly on the road. The Cummins L9 SCR 2022-2024: OEM 5507861 is a core Selective Catalytic Reduction (SCR) component engineered to reduce harmful nitrogen oxides (NOx) in exhaust gas. Understanding how this SCR unit contributes to effective emission reduction can help truck owners and maintenance teams make confident service and replacement decisions.

  • Specifically designed for Cummins L9 engines from 2022 to 2024, the OEM 5507861 SCR unit fits precisely into the emission aftertreatment system to ensure proper integration.

  • The SCR (Selective Catalytic Reduction) system works by injecting diesel exhaust fluid (DEF) into the exhaust stream, where it triggers a catalytic reaction that converts NOx into harmless nitrogen and water vapor.

  • Installing the genuine OEM 5507861 SCR guarantees compatibility with your engine’s emission control strategy, reducing the risk of diagnostic trouble codes or false emission alerts.

  • A properly functioning SCR supports accurate DEF delivery, which helps maintain efficient NOx reduction and prevents unnecessary DEF waste.

  • Replacing worn or aging SCR components with the correct OEM unit helps avoid service interruptions related to emission system faults or warning lights.

  • Reliable SCR operation supports seamless communication between emission sensors and the engine control module, minimizing false signals that could affect truck reliability.

  • Built to meet Cummins’ original manufacturing standards, this SCR module provides the durability needed to withstand the heat, vibration, and conditions typical of highway and regional use.

  • Installation is straightforward for professional technicians and maintenance teams during routine emission system checks or component replacements.

Choosing the Cummins L9 SCR 2022-2024: OEM 5507861 from Tamerx Diesel Parts means equipping your emission control system with a high-quality, engine-specific component. With the right SCR unit in place and proactive system care, your truck will remain emission-compliant, dependable, and ready for the demands of daily operation.

The Selective Catalytic Reduction (SCR) system is a sealed component within the diesel aftertreatment system, designed to reduce nitrogen oxide (NOx) emissions using Diesel Exhaust Fluid (DEF). While the SCR catalyst itself does not contain moving parts or fluid passages like a radiator, certain failures can create conditions that resemble internal leaks or exhaust flow issues.

  • Cracks in the SCR housing caused by impact or vibration can allow exhaust gases to escape before proper treatment.

  • Internal substrate damage may create gaps or channels that disrupt normal exhaust flow through the catalyst.

  • Failed gaskets or loose exhaust connections near the SCR can mimic internal leak symptoms.

  • DEF injector leaks upstream of the catalyst may lead to improper dosing and crystallization buildup.

  • Corrosion from long-term contamination can weaken the outer shell or welded seams of the unit.

  • Excessive heat stress may contribute to structural fatigue over time.

Symptoms of a potential SCR leak may include unusual exhaust noise, reduced emissions efficiency, fault codes, or visible exhaust soot around connection points. A thorough inspection of the exhaust system, including pressure testing and visual checks, can help determine whether the issue involves the SCR housing, surrounding components, or related connections. Prompt repair helps maintain proper emissions control and prevent further damage to the aftertreatment system.

Yes, the engine control system may limit power if it detects emissions treatment faults to protect overall system health. This protective mode helps manage emissions until the issue is resolved.

While its main role is emissions control, efficient SCR operation supports balanced engine performance. A properly functioning SCR can indirectly help the engine operate more efficiently.

Persistent warning lights, unusual exhaust smokes, or repeated DEF alerts often signal attention is needed. These are signs the emissions system isn’t working as expected.

Cold temperatures can temporarily affect DEF behavior, and very hot conditions can strain SCR components. Systems are designed to handle extremes, but weather can still influence operation.
