Return policy

The vast majority of products available at Thoroughbred Diesel are returnable. To initiate a return, you must request a Return Merchandise Authorization Number (RMA#) within 30 days of receipt of the product.

All items must have an RMA# and be received in a new, unused and ready-to-sell condition (including all original packaging, parts, and paperwork) to receive a refund, excluding any shipping costs.

All returns require a 15% restocking fee and are subject to inspection before a credit is issued. On exchanges there will be no restocking fee.

Thoroughbred Diesel does not accept returns on used items, custom-painted products or items shipped via truck freight.

International orders cannot be returned or exchanged unless the item is defective or in the case of an error on our part.

Thoroughbred Diesel will not reimburse labor charges or installation fees under any circumstances.

Orders placed using PayPal or Bill Me Later must pass an inspection before any credit will be issued.

Return procedure

All return items require a Return Merchandise Authorization Number (RMA#).

To get an RMA# simply fill out this form online, click here.

We'll email you within 2 working days with an RMA#.

Shipments received without a valid RMA# clearly posted on the outside of the box will be charged a 15% restocking fee.

Thoroughbred Diesel is not responsible for items returned without proper return information (customer's name, address and RMA#) on or in the box.

Defective items

If an item arrives in an unacceptable condition as a result of a manufacturer defect, we will send you a pre-paid return shipping label.

To get a shipping label and a valid RMA#, see our full return procedure above. Once you've received the label and the RMA#, ship the defective item as instructed by your customer care specialist. Once we've confirmed the package is in transit we'll ship you a replacement or credit your account.

Restocking Fees

All returns require a 15% restocking fee and are subject to inspection before a credit is issued. On exchanges there will be no restocking fee.

Credits

All returned item(s) will be inspected upon receipt and must meet the following criteria for a credit:

• The item(s) must be returned in a new condition
  All items returned for a refund or exchange must be in a new and ready-to-sell condition. This includes all installation hardware, instructions, packaging and paperwork.
• The returned package must be clearly labeled with a proper Return Merchandise Authorization Number (RMA#)
  Items returned without an RMA# clearly displayed on the box will be charged a 15% restocking fee. For more information on how to obtain an RMA#, click here.

The original credit card used to place the order will be credited for the purchase price of the item and any applicable sales tax, excluding all shipping costs.

Exchanges/Replacements

Items to be replaced must meet the same conditions as items returned to Thoroughbred Diesel for a refund. Non-defective items returned for exchange must be in a new and ready-to-sell condition with all original packaging, paperwork and parts included. Defective items must also be returned with the same items included in the original order.

If you request a replacement, we will ship your new item after we receive and process your return. Please allow 5-10 business days to process your return once it has been received.

If you need a replacement item right away, we suggest placing a new order on our website, or email us at sales@ThoroughbredDiesel.com or call us at 866-737-4966 for expedited ordering. Express shipping charges may apply for rush orders.

Shipments without a proper Return Merchandise Authorization Number (RMA#) will be charged a 15% restocking fee.

Non-returnable Products

Most of the items available at Thoroughbred Diesel may be returned for full or partial credit. However, some items for your specific vehicle are not returnable.

In the case of defect or our error, these items may be returned for full or partial credit, depending on the circumstances.

The vast majority of our customers are extremely happy with their items and never need to return them.

How do I return an item?

If you've decided to return an item to us, you'll need a Return Merchandise Authorization Number (RMA#). All returns require an RMA# in order for us to accept shipment of your item(s).

To get an RMA# simply fill out this form online, click here.

We'll email you within 2 working days with an RMA# for your order. The Customer Service Representative contacting you will have further instructions for your easy return.

Will I have to pay a restocking fee?

All returns require a 15% restocking fee and are subject to inspection before a credit is issued. On exchanges there will be no restocking fee.

Who pays for return shipping costs?

Thoroughbred Diesel covers return shipping costs if the return is due to a manufacturing defect or as a result of our error. We will provide you with a pre-paid UPS label to return the product(s) to us in this situation.

Items returned for reasons other than defect or Thoroughbred Diesel error will not be provided with a pre-paid UPS return label. These returns include reasons such as "changed my mind," "did not like the product" and "ordered the incorrect product".

I received the wrong item for my vehicle. What do I do now?

First, verify that the part number you ordered and the part number you received are the same item.

If the part numbers match, you may have ordered the incorrect part number for your vehicle. We'll process your return and exchange the item for the correct part (if available).

If the numbers do not match, you may have been erroneously shipped the wrong part for your vehicle. While this is an extremely rare case, it can happen with the volume of orders we ship from our manufacturers and fulfillment centers. A prepaid UPS shipping label will be sent for returning the incorrect item, assuming you received the incorrect part through our error.
