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.
The International Navistar DOC: OEM 2596407C92 is designed to provide accurate fit and dependable function for select Navistar diesel engines.

The Navistar Diesel Oxidation Catalyst (DOC), part number 2596407C92, is an essential emissions control module for International/Navistar MaxxForce DT (I‑326/I‑340) engines, as well as MaxxForce 9 and MaxxForce 10 platforms. Often referred to as the “Converter DOC Assembly,” it is the first step in aftertreatment of diesel exhaust.
What It Does
As exhaust gases pass through the DOC, a catalytic reaction occurs on a precious-metal-coated substrate. This reaction performs several critical conversions:
- Transforms harmful gases
- such as carbon monoxide (CO) and unburned hydrocarbons (THC) into less harmful byproducts like carbon dioxide (CO₂) and water vapor.
- Converts nitric oxide (NO) into nitrogen dioxide (NO₂)
- a gas that plays a vital role in enabling passive regeneration of the downstream Diesel Particulate Filter (DPF). This process allows soot to burn off naturally during normal engine operation—without needing extra fuel or high-temperature cycles.
This DOC acts as a key cleaning step right at the start of the exhaust flow. It reduces the burden on the rest of the aftertreatment system by:
-
Lowering pollutant levels from the outset
-
Enabling smoother, more efficient DPF regeneration
-
Supporting emissions compliance with less maintenance and reduced active regeneration requirements
Built to OEM specs and often packaged with gaskets, clamps, and warranty support, the OEM 2596407C92 provides a durable and reliable solution for heavy-duty diesel applications.
The Diesel Oxidation Catalyst (DOC) is a key component in reducing harmful emissions from diesel engines. Over time, ash and soot can build up inside the DOC, affecting its ability to treat exhaust gases. When issues arise, many wonder: is it better to clean the DOC, or simply replace it?
When Cleaning Makes Sense
In many cases, cleaning the DOC is a cost-effective and practical solution. Cleaning helps remove buildup and restore flow without the expense of a new part. It’s typically recommended when:
- The DOC is structurally intact
- There are no signs of internal melting or damage
- Emissions-related fault codes are triggered due to blockage
- The vehicle has reached its scheduled service interval
When Replacement Is the Better Option
You may need to replace the DOC if:
- There are visible cracks or physical damage
- The internal substrate has melted or broken apart
- Cleaning has been attempted but flow remains restricted
- You’re dealing with repeated failures or high backpressure
Cleaning is usually sufficient for maintenance or moderate clogging. However, if the DOC is damaged or no longer functioning effectively after service, replacement may be necessary for long-term reliability and compliance.
It is a diesel oxidation catalyst designed to reduce emissions in International/Navistar engines.
It fits select International/Navistar diesel engines requiring part number 2596407C92.
It converts harmful exhaust gases like hydrocarbons and carbon monoxide into cleaner emissions.
Yes, it is manufactured to replace the original OEM component without modifications.
