Anything after the 30 days we will handle it case by case.

Defective Items
In the event an item arrives in an unacceptable condition as a result of a manufacturer defect, Thoroughbred Diesel will go above and beyond to resolve the issue. Follow our Return Procedure to easily handle any returns.

Damaged Items
Thoroughbred Diesel thinks UPS and FedEx are great! However, in the event a package appears damaged during shipping, please take pictures of everything and contact us to get it taken care of.

Items in new condition (including original packaging, paperwork, hardware and instructions) may be returned for exchange. No restocking fee will be charged on exchanges. Shipping Charges occurred for sending original product will not be refunded.

Thoroughbred Diesel does not manufacturer any of the products they carry and therefore do not imply nor offer any warranty on them. All product warranties if any, implied have been done so at the discretion of the manufacturer. If you need warranty assistance on any product you’ve purchased, please contact the manufacturer directly.

Cancellation Policy
Once an online or phone order is placed, it is processed in a timely manner. Should you have the need to change part or all of your order, you must call and speak to someone in our Order Department. Requests to change part or all of an order will be accommodated only if the order has not yet been processed and sent to the warehouse for shipping. If your order has already been processed, you will need to follow the steps for a RMA request outlined in our Return Policy. In some cases, additional charges may be incurred (i.e. to stop a package already in transit, restocking fee, etc.) but those will be reviewed and discussed with the customer before they are applied.

We only ship to the fifty U.S states and Canada which excludes all other international destinations. In the event that you, the customer, places an order to an International address not listed above, Thoroughbred Diesel reserves the right to cancel your order and issue a full refund.

* In most cases Thoroughbred Diesel 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. If you want to ship to an address different from your billing address, we require a copy of your driver's license faxed (859-737-1865) or emailed to sales@thoroughbreddiesel.com.

* Shipping Times
  • Most products ordered will ship within 1-2 business days. Some exceptions may include back ordered and/or direct ship items. Thoroughbred Diesel has numerous warehouses across the country allowing us to reach 90% of the U.S. within 2 days.
  • Non-stock, special order and out of stock items may take 1-2 weeks to be received. If you would like to check inventory or estimated ship date please contact us toll-free at 866-737-4966.

* APO/FPO Shipping (Military Address) – Thoroughbred Diesel cannot ship product directly to APO or FPO addresses because we exclusively use UPS/Fed Ex/USPS for shipments and they do not allow shipments to these addresses. As an option, you may want to consider shipping to a stateside street address and then sending the package to the APO/FPO address overseas via the US Postal Service.
Core Policy

What is a Core?
Many stock replacement parts such as turbos, injectors, injection pumps, and high pressure oil pumps have a core charge that is associated with the new replacement part. You must return the old part to receive a refund on the core charge. All cores must be like for like and include all parts and pieces that were received on your new replacement product.

Core Return Label
The core return label is a new option offered by Thoroughbred Diesel to customers that buy products that have a core charge. For a small fee Thoroughbred Diesel will send you a core return tag either to your email or right to your mail box. This will save you money on the return shipping and will make sure your cores get returned correctly. The label will be insured to protect your core. This will make it a complete hassle free process. Only available for the 48 contiguous states. If you have any questions on it contact cores@thoroughbreddiesel.com.

No upfront Core Charge
No upfront Core Charge Thoroughbred Diesel has implemented a policy on many products that eliminates the upfront core charge at time of purchase reducing out of pocket expense to the consumer on some products. On parts that are not charged core you will have 14 business days from the time of receipt of the product to get the core back to Thoroughbred. You will be sent a pre-paid shipping label separate through email. If you have any problems contact cores@thoroughbreddiesel.com.

PayPal & All Other Non-Credit Card Orders
All non-credit card orders, such as PayPal, and eBay will require that we have a credit card on file on orders with no core value. The on file credit card will not be charged unless the core is not returned in the specified time frame. A Thoroughbred Diesel Sales Agent will contact you to obtain a credit card for your order.

Core Physical Condition
All cores must be in re-buildable condition to receive a full refund of the core charge. There are some conditions that you will not receive full credit. On these conditions it is up to the manufacture on the amount of credit issued.

  • Burnt
  • Water Damage
  • Broken
  • Disassembled
  • Missing parts and/or pieces

Core Charge Timeline

  • If the core is returned after 30 days, 90% of the core will be refunded.
  • If the core is returned after 60 days, 70% of the core will be refunded.
  • If the core is returned after 90 days, 50% of the core will be refunded.
  • After 6 months cores will be accepted at Thoroughbreds discretion

Core Return Procedure

  1. Please keep all original packaging of your new item to be used for the core return.
  2. Drain all fluids: oil, fuel, etc. out of the core before it is returned.
  3. Place any plastic plugs or caps received on the new item back onto the core.
  4. To insure UPS, Fed Ex, or USPS will not reject the package due to fuel or oil leakage, please put inside and wrap in plastic garbage bag.
  5. Place core inside the box.
  6. If there was core return paperwork inside the box, please complete the form and send back with the core.
  7. Thoroughbred Diesel provides a pre-paid shipping label for any product that does not require an upfront core charge. This is usually sent to the email address provided via UPS within 2-3 days.
    1. If you are charged for the core upfront you are responsible for the shipping charges on the core. You can use any shipping provider you prefer. We recommend using someone with tracking numbers.

*If you are charged for the core upfront you are responsible for the return shipping cost.

*If for any reason, you decide to return the part, DO NOT use the return label provided because it will be processed as a core.

*Customers outside the continental US (lower 48 states) will be responsible for shipping the core back. UPS return service labels can only be sent to customers in the lower 48 US states.

*If you are responsible for shipping the core back to Thoroughbred Diesel, please provide a tracking number to cores@thoroughbreddiesel.com. Without a confirmed tracking number, we cannot guarantee your core refund.
