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.

Diesel trucks must meet strict emission standards while remaining reliable for everyday operation. The Cummins L9 SCR 2022–2024: OEM 5507877 is a Selective Catalytic Reduction (SCR) component engineered to reduce harmful nitrogen oxides (NOx) in exhaust gas. Focusing on how this SCR unit improves emission aftertreatment efficiency helps truck owners and service teams make informed maintenance and replacement decisions.

  • Designed specifically for Cummins L9 engines from 2022 to 2024, the OEM 5507877 SCR unit integrates precisely into the emission aftertreatment system for dependable function.

  • The SCR (Selective Catalytic Reduction) system works by introducing diesel exhaust fluid (DEF) into the exhaust stream, triggering a chemical reaction that converts NOx into harmless nitrogen and water vapor.

  • Installing the genuine OEM 5507877 SCR ensures proper compatibility with your engine’s emission control system, reducing the chance of diagnostic trouble codes and emission-related warning lights.

  • A properly functioning SCR supports accurate DEF dosing, which contributes to efficient NOx reduction and helps avoid unnecessary DEF consumption that can occur with poorly fitting parts.

  • Replacing worn or compromised SCR components with the correct OEM unit helps prevent emission faults that can lead to service interruptions and unplanned downtime.

  • Effective SCR performance enhances communication between emission sensors and the engine control module, leading to smoother system response and fewer false error signals.

  • Built to meet Cummins’ original manufacturing specifications, this SCR module withstands heat, vibration, and the operating conditions typical of highway and regional use.

  • Installation is straightforward for technicians and maintenance professionals during routine emission system servicing or part replacement intervals.

Choosing the Cummins L9 SCR 2022–2024: OEM 5507877 from Tamerx Diesel Parts means equipping your emission control system with a high-quality, engine-specific component. With reliable SCR function and proper maintenance, your truck will stay emission-compliant, dependable, and ready for the challenges of everyday driving.

The Selective Catalytic Reduction (SCR) system is essential for reducing nitrogen oxide (NOx) emissions in modern diesel engines. While SCR components are built for durability, neglect or contamination can lead to warning lights, reduced power, and costly repairs. Preventative maintenance and proper system care are the best ways to avoid SCR failure and keep your diesel engine operating reliably.

  • Always use clean, manufacturer-approved Diesel Exhaust Fluid (DEF). Contaminated or incorrect fluid can damage the catalyst and cause dosing issues.

  • Store DEF properly in a sealed container and avoid exposure to dirt, water, or extreme temperatures that could affect fluid quality.

  • Address engine issues such as oil consumption, coolant leaks, or injector problems immediately to prevent contamination of the exhaust system.

  • Keep the Diesel Particulate Filter (DPF) functioning correctly. Unresolved soot buildup can affect exhaust temperatures and place added stress on the SCR.

  • Monitor dashboard warning lights and diagnose fault codes promptly instead of delaying repairs.

  • Follow scheduled maintenance intervals to inspect DEF filters, sensors, and related aftertreatment components.

Preventing SCR failure comes down to consistent maintenance and early problem detection. By maintaining proper DEF quality, repairing engine concerns quickly, and keeping the aftertreatment system in good condition, you can extend the lifespan of the SCR and avoid unexpected downtime.

Frequent warnings often result from low or contaminated DEF, sensor errors, or inconsistent SCR reactions. Checking DEF supply and sensor health helps isolate the root cause.

Yes — short trips and stop-and-go traffic can make it harder for the system to reach and maintain optimal reaction temperatures. Longer, steady driving often provides better conditions for SCR function.

It helps ensure NOx levels are low enough to pass regulated emissions tests by converting harmful gases before they exit the vehicle. Poor SCR performance can lead to failed test results.

Keeping the SCR system and related sensors in good condition helps prevent unexpected emissions faults and derates. Consistent performance promotes smoother operation and fewer service interruptions.
