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.

No upfront Core Charge

Thoroughbred Diesel has implemented a policy on a few products that eliminates the upfront core charge at the time of purchase to reduce the out of pocket cost for customers. On parts that are not charged a core, you will have 14 business days from the time you receive the product to get the core back to Thoroughbred. If the core is not returned within 14 business days from the time you get your order, we will be charging the credit card we have on file. If the core is not sent back within 30 days full core amount may not be refunded, See core timeline below. You will be sent a pre-paid shipping label separate through email from UPS. 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 where the core wasn’t charge upfront. 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.

   • 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.
