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.

This turbo assembly plays a major role in how your engine performs — here’s why it matters:

  • Delivers Optimal Boost Pressure – Compresses incoming air to increase oxygen supply for more efficient combustion and improved power delivery.

  • Enhances Engine Responsiveness – Proper turbo function helps reduce lag and supports consistent acceleration and load response.

  • Supports Fuel Efficiency – Accurate boost levels help the engine achieve more complete combustion, contributing to improved fuel economy.

  • OEM-Grade Fit and Durability – As OEM 5606178RX, this turbo assembly matches original specifications for correct fitment, airflow performance, and long-lasting durability under demanding conditions.

  • Protects Engine Components – Maintaining the right air-to-fuel ratio helps reduce stress on internal components, promoting smoother operation and extended engine life.

A worn or failing turbocharger can lead to reduced performance, increased exhaust smoke, and higher fuel consumption. The Cummins ISL-450 Turbo Assembly (OEM 5606178RX) delivers the precision and OEM-standard reliability needed to keep your engine running smoothly, efficiently, and dependably. For customers seeking a trusted replacement, Tamerx offers high-quality turbo assemblies designed to support consistent performance and long-term engine health.

Choosing the right turbo assembly is essential for achieving proper engine performance, efficiency, and reliability. Whether you’re replacing a worn turbo or upgrading your system, selecting the correct unit ensures compatibility, prevents engine stress, and helps maintain long-term durability. Understanding what to look for makes the decision much easier and avoids costly mistakes.

Key Factors to Consider When Selecting a Turbo Assembly

  • Match the Turbo to Your Engine Model
    Always verify compatibility with your vehicle’s year, make, engine size, and OEM specifications. Using the wrong turbo can lead to fitment issues or engine damage.

  • Determine OEM vs. Aftermarket
    OEM turbos offer guaranteed compatibility, while aftermarket options may provide performance gains—just ensure they meet quality standards.

  • Understand Your Performance Needs
    Daily driving, towing, or performance applications may require different turbo sizes or boost characteristics.

  • Check the Turbo’s Specifications
    Pay attention to turbine size, compressor wheel design, wastegate style, and boost pressure ratings to ensure proper performance.

  • Consider the Quality of Materials
    High-grade bearings, housings, and internal components improve reliability and extend turbo lifespan.

  • Review Warranty and Support
    A good warranty and reputable manufacturer ensure long-term support and confidence in your investment.

  • Inspect Related Components
    Sometimes additional parts—such as gaskets, actuators, or oil lines—must be replaced or upgraded to ensure proper installation.

Choosing the right turbo assembly requires understanding your vehicle’s specifications, performance needs, and the quality of available options. Taking the time to select a compatible, well-built turbo helps protect your engine, improve performance, and ensure long-term reliability. With the right turbo, your vehicle can deliver confident and efficient power for many miles ahead.

Premature failure often stems from poor lubrication, contaminated oil, or debris entering the turbocharger. Regular oil changes and preventing intake contamination help reduce the risk of early wear.

With proper maintenance and routine service, this turbo assembly can last many thousands of miles. Lifespan varies based on operating conditions, maintenance habits, and load demands.

Before starting the engine after installation, it’s recommended to prime the turbo assembly with clean engine oil. Priming ensures proper lubrication and helps protect internal components from early wear.

A well-functioning turbo assembly supports efficient air-to-fuel balance, which can enhance fuel efficiency during typical operation. A worn or malfunctioning turbo may lead to increased fuel consumption.
