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.

When your Cummins ISB 6.7 engine is overdue for a DPF swap, choosing a rugged, precise replacement matters more than just keeping emissions in check—it ensures smooth, uninterrupted regeneration and preserves the health of your entire aftertreatment system. Built to Cummins OEM standards, the Cummins ISB 6.7 DPF: OEM 5579372RX is designed to restore optimal exhaust flow, promote efficient soot cleanup, and help your DOC and SCR components live longer.

  • Restores Optimal Exhaust Flow Dynamics
    The OEM 5579372RX is engineered to deliver the right level of filtration resistance, helping return your engine to proper exhaust backpressure. This balance supports stable airflow and keeps regeneration cycles flowing as designed.

  • Promotes Efficient Regeneration Cycles
    With consistent flow and exhaust temperatures, both passive and active DPF regeneration occurs more reliably. That means fewer forced regen events, less downtime, and a more predictable maintenance schedule.

  • Protects Downstream Aftertreatment Components
    A clean, effective DPF prevents soot and particulate matter from harming sensitive downstream parts like DOC units, SCR catalysts, and NOx sensors—helping you avoid costly repairs and maintain system integrity.

  • Seamless Fit, Hassle-Free Installation
    Crafted to Cummins OEM specifications, the OEM 5579372RX fits precisely in your ISB 6.7 system. This ensures fast, accurate installation with minimal downtime—and no guesswork or modifications required.

  • Warranty-Assured Quality & Simple Core Return
    Backed by solid warranty coverage, this DPF delivers both durability and peace of mind. The vehicle owner also benefits from a straightforward core charge process—return your old DPF, get credited promptly, and stay on top of cost-effective service.

Don’t let a worn DPF slow you down or compromise downstream systems. Opting for the OEM 5579372RX ensures clean regeneration, smooth operation, and lasting protection for your Cummins ISB 6.7’s aftertreatment system. Trust Tamerx Diesel Parts to provide the genuine, reliable components your engine deserves.

 

The Diesel Particulate Filter (DPF) is essential for controlling emissions in diesel engines. When the DPF warning light appears on your dashboard, it's your vehicle’s way of telling you that action is required to prevent engine or emission system damage. Ignoring the warning could lead to expensive repairs or reduced vehicle performance.

Steps to Take When the DPF Warning Light Comes On

  • Continue Driving at Highway Speeds (If Safe)
    Most modern diesel vehicles perform automatic regeneration during sustained highway driving. Maintain speeds above 40 mph for at least 15–30 minutes to allow the system to burn off soot.

  • Avoid Short, Low-Speed Trips
    Stop-and-go traffic prevents proper regeneration. Try to plan routes that allow your vehicle to sustain higher speeds for a continuous period.

  • Check for Other Warning Lights
    If the check engine light or other indicators are also on, your vehicle may not be able to regenerate. In this case, you’ll need diagnostics to clear faults and enable regeneration.

  • Manual or Forced Regeneration
    Some vehicles allow manual regeneration via a button. If unavailable or unsuccessful, a repair shop can perform forced regeneration using diagnostic tools.

  • Do Not Delay Maintenance
    If the light stays on even after attempted regeneration, it may indicate an overly clogged filter. Continued driving could trigger limp mode or engine derate.

  • Inspect Related Systems
    Problems with sensors, the EGR system, or the turbocharger can affect DPF function. A technician should inspect these areas if regeneration fails.

A DPF warning light is a sign to act—quickly. Start with highway driving to allow passive regeneration, but if the issue persists, seek professional diagnostics to prevent engine damage. Regular maintenance, using the correct low-ash oil and diesel, and avoiding excessive idling can help you avoid future DPF issues.

Ignoring alerts may cause irreversible clogging, lower engine performance, and expensive repairs.

Continued restriction raises exhaust temperatures and wears engine components, reducing efficiency.

A stable and acceptable differential pressure reading across the filter confirms it's functioning properly.

Unchecked soot buildup can lead to excessive backpressure, engine strain, overheating, and ultimately system failure.
