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 Cummins ISC 8.3L Turbo Assembly is a key component designed for heavy-duty engines, especially those found in trucks, buses, and industrial equipment. This turbo assembly plays a critical role in maximizing engine efficiency by improving air intake and exhaust management, helping to maintain optimal fuel combustion.
Here are some key components and their functions:
- Turbocharger Housing
- Protects and supports the turbine and compressor, ensuring air flows effectively through the system.
- Compressor Wheel
- Compresses air, increasing its density before entering the engine, allowing for more efficient combustion.
- Turbine Wheel
- Harnesses energy from exhaust gases, spinning the compressor to force more air into the engine.
- Wastegate
- Controls the boost pressure, preventing excess pressure buildup in the system.
The turbo assembly is vital for maintaining consistent power output while improving fuel efficiency. It ensures that the engine can handle heavy loads without losing power. The Cummins ISC 8.3L Turbo Assembly, particularly the OEM 4955704RX, is designed to fit the specific needs of vehicles from 2004 to 2008, offering long-lasting durability and effective air management for demanding applications.
A failing turbo assembly can cause a variety of issues that impact the overall efficiency of your vehicle. Early detection of these symptoms can help prevent further damage to your engine. Here are some key signs to look out for if you suspect your turbo assembly might be failing.
Symptoms of a Failing Turbo Assembly:
- Power Loss
- You may notice a significant drop in power, especially when accelerating or climbing hills.
- Excessive Smoke
- Blue or black smoke from the exhaust could indicate oil is leaking into the combustion chamber, a common issue with turbo problems.
- Whining Noise
- A high-pitched whining or siren-like sound coming from the engine is often a clear indicator of a turbo issue.
- Check Engine Light
- If your check engine light comes on, it could be triggered by sensors detecting problems with the turbo assembly.
If you observe any of these signs, it’s essential to address the issue promptly to avoid further complications. A well-functioning turbo helps ensure your vehicle operates smoothly, and early repairs can save you from more costly fixes down the road.
Diagnosis involves listening for unusual noises, checking for excessive exhaust smoke, inspecting for oil leaks around the turbo assembly, and monitoring for a decrease in engine working condition.
Operating a vehicle with a malfunctioning turbo assembly is not advisable, as it can lead to further engine damage and decreased durability.
Regular inspections should be performed every 50,000 miles, and replacement is typically needed between 150,000 and 300,000 miles depending on engine conditions.
Yes, excessive backpressure, poor airflow, or oil leaks can cause piston damage, excessive soot buildup, or engine overheating.
