Most products we sell are returnable. Returns will be accepted if the product is in new, uninstalled and unopened condition with all original packaging and paperwork, or if the item is defective or was damaged during shipping. Items that have been opened, installed, mounted, welded, or altered in any way are not returnable. All product returns must be pre-authorized within 30 calendar days of purchase. After 30 days all warranty or other issues must be handled with the product manufacturer. Parts received without pre-authorization will be held with no action until contact is made by customer.
Upon receipt, all returns will be inspected. If the item is damaged from installation, is missing components, manuals, original packaging, the product serial number doesn’t match the original serial number we shipped out, or for any reason the product is deemed not re-saleable due to customer actions, at our discretion, credit may be refused or a restocking fee of up to 20% may be assessed. Some items such as exhaust systems might have a re-boxing fee of up to $35 if the box is damaged to the point where it is no longer serviceable.
Complete this RMA FORM. Within 3 business days we will email detailed return instructions to you. Mail the item back to us following the instructions. Unless the return is due to manufacturer defect or U.S. Diesel Mods error, you the customer are responsible for return shipping costs.
Please allow 3-5 business days from the time the product arrives at our warehouse until your refund or replacement product is processed.
If you are to receive a replacement product, you will be emailed tracking information for your new item. If you are to receive a refund, your original payment method will be credited the purchase price. You will receive an email confirmation when we refund your credit card or Paypal account. Please allow up to 7 business days for your bank to process the credit to your card.
Returns missing components will not be credited. Parts that have been disassembled or damaged due to incorrect installation will not be credited. We are not responsible for incorrect installation by you and/or your mechanic. We are also not responsible for any expenses incurred or caused by the use of wrong or defective parts during installation. These expenses include towing, labor, repair or rental car expenses.
Some custom-order or special-order items are not returnable. These include (but are not limited to) chargers, blowers, turbos, clutches and some lift kits. If you experience issues with one of these non-returnable items, we will do everything we can to help, but all warranty work and tech support must go through the product manufacturer.
