Return & Refund Policy
At Diesel Proof, we want you to be confident in the parts you purchase from us. If you need to request a return, please review the policy below and contact us before sending any product back.
Return Eligibility
Eligible products may be returned within 30 days of delivery. To qualify for a return, the product must be:
- New, unused, and uninstalled
- In resalable condition
- In the original packaging with all included components, hardware, instructions, and documentation
- Accompanied by proof of purchase from Diesel Proof
All returns require authorization from Diesel Proof before the product is shipped back. Products returned without prior authorization may be refused or returned to the sender.
Non-Returnable Products
Unless otherwise required by applicable law, the following are generally not eligible for return:
- Products that have been installed, used, modified, damaged, or altered
- Electronic tuners, programmers, modules, or other electronic products that have been installed, connected, registered, VIN-locked, or otherwise activated
- Custom-made, special-order, or made-to-order products
- Clearance or final-sale products
- Products missing original packaging, hardware, components, or documentation
- Products damaged due to improper installation, misuse, or handling
- Certain products subject to manufacturer-specific return restrictions
- Core charges and core components, which are governed by our separate Core Charge Policy
If you're unsure whether a product is returnable, contact Diesel Proof before purchasing or beginning installation.
Return Shipping
Unless the return is the result of an error by Diesel Proof, an incorrect shipment, or a verified defective/damaged product, the customer is responsible for return shipping costs.
Original shipping charges, expedited shipping charges, freight charges, and other shipping-related fees are generally non-refundable.
Some returns may be subject to a restocking fee imposed by the manufacturer, distributor, or fulfillment partner. If a restocking fee applies, we will communicate it as part of the return authorization process.
Diesel Proof does not impose a standard restocking fee on returns. However, some manufacturers, distributors, or fulfillment partners may charge a restocking fee on returned products. When a restocking fee applies to your return, that amount will be deducted from the refund. We will communicate any applicable restocking fee during the return authorization process whenever possible.
Damaged, Defective, or Incorrect Orders
Please inspect your order as soon as it arrives.
If your order arrives damaged, contains the wrong product, or appears to have a manufacturing defect, contact Diesel Proof as soon as possible with your order information and photos of the product, packaging, shipping label, and any visible damage.
Do not install a product that appears damaged or incorrect. Installation may affect our ability to resolve the issue with the manufacturer or shipping carrier.
Manufacturer defects may be handled under the applicable manufacturer's warranty rather than as a standard return.
Refunds
Once an authorized return has been received and inspected, we will notify you of the status of your refund.
Approved refunds will be issued to the original payment method. Any applicable restocking fees, non-refundable shipping charges, or other authorized deductions will be deducted from the refund.
Please allow your financial institution additional time to process and post the refund after it has been issued.
Order Cancellations
If you need to cancel an order, contact us as soon as possible.
Because many Diesel Proof products are fulfilled directly through manufacturers and distribution partners, we cannot guarantee that an order can be canceled once it has entered processing or fulfillment. Orders that have already shipped must follow the applicable return process.
Special-order, custom, or made-to-order products may not be cancelable once the order has been submitted to the manufacturer.
Fitment
Customers are responsible for confirming vehicle fitment before installation. If you are unsure whether a product fits your truck, contact Diesel Proof before ordering or installing the product.
Do not attempt to install a product that appears incorrect for your application.
How to Request a Return
To request a return, contact Diesel Proof with:
- Your order number
- The product you would like to return
- The reason for the return
- Photos, when applicable
Our team will review the request and provide return instructions if the product is eligible.
Do not ship a return to the address shown on your original package unless specifically instructed to do so. Because we work with multiple manufacturers and fulfillment locations, the correct return destination may differ by product.
