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.

A reliable emissions control system starts with a solid foundation—and the Diesel Oxidation Catalyst (DOC) is a critical part of that. The OEM 5011044R1 DOC, designed for International Navistar vehicles, ensures cleaner exhaust and dependable aftertreatment performance. What makes it a smart choice? Let’s break it down.

  • Transforms Pollutants Early
    This DOC effectively converts harmful emissions like hydrocarbons and carbon monoxide into cleaner, less harmful compounds at the beginning of the exhaust stream—setting the stage for enhanced downstream efficiency.

  • Supports Smooth Regeneration
    Consistent exhaust quality helps maintain ideal temperature and airflow—making Diesel Particulate Filter (DPF) regeneration more predictable and reducing the likelihood of interrupted operations.

  • Protects Sensitive Aftertreatment Components
    By removing contaminants early, it shields downstream parts like SCR units, sensors, and the DPF itself, guarding them from soot-related damage and prolonging their life.

  • Made for a Seamless Fit
    Engineered specifically to match International Navistar specifications, this DOC ensures a precise fit and easy installation—no modifications or guesswork needed.

  • Reliable Service with Warranty & Core Return
    Backed by warranty support and an easy core return program, the OEM 5011044R1 offers lasting quality and value that keeps both your system and budget running smoothly.

Choosing the OEM 5011044R1 DOC means investing in cleaner exhaust chemistry, smoother system operation, and long-term component protection. Count on Tamerx Diesel Parts to deliver OEM-quality solutions that keep your International Navistar running cleanly and reliably.

The Diesel Oxidation Catalyst (DOC) is a vital part of your diesel aftertreatment system, responsible for reducing harmful emissions like carbon monoxide and unburned hydrocarbons. To maintain its effectiveness and ensure compliance with emissions regulations, regular inspection is essential. But how often should you actually check the DOC?

Recommended Inspection Frequency for DOC Filters

  • Routine Inspection Every 6 Months
    For most on-road diesel engines, inspecting the DOC every 6 months or approximately every 50,000 miles is a safe benchmark, especially for vehicles operating under normal driving conditions.

  • Inspection During Every Preventive Maintenance Interval
    Include a DOC visual check during scheduled preventive maintenance. Look for signs of physical damage, soot buildup, or any exhaust restrictions.

  • More Frequent Checks in Harsh Environments
    Vehicles operating in extreme conditions (e.g., heavy stop-and-go driving, dusty environments, or towing heavy loads) should have their DOC inspected more frequently—every 3 to 4 months.

  • After Regeneration Failure or DPF Issues
    If your system has trouble completing regenerations or the DPF shows signs of early clogging, inspect the DOC immediately. These symptoms may indicate a failing or obstructed catalyst.

  • At Each Scheduled Emissions Test
    Make DOC inspection part of the prep for mandatory emissions testing to ensure it’s not contributing to elevated emissions or system inefficiency.


Regular inspection of the DOC not only supports clean emissions but also helps identify developing issues before they lead to costly repairs. By aligning inspections with maintenance intervals and being mindful of driving conditions, you can keep your DOC functioning effectively and extend its overall service life.

Elevated tailpipe emissions or higher-than-normal exhaust temperatures often indicate reduced catalytic efficiency.

A clogged DOC causes increased exhaust backpressure, which can reduce engine power and efficiency.

Monitoring differential temperature and using diagnostic data helps evaluate when the DOC is performing correctly.

Ensuring clean exhaust input and periodic inspections during DPF servicing helps maintain its function.
