Thunder Diesel & Performance Return Policy

                                                                                     Oct. 15, 2015

To ensure your satisfaction, we permit our customers to return items purchased from Thunder Diesel & Performance, subject to the limitations and procedures set forth below.

                                                          90 Day Return Period

You may return an item purchased from Thunder Diesel & Performance for any reason up to 90 days from the original Invoice date, provided that the item has not been installed and is in “brand-new” condition.


                                           Return Merchandise Authorization

To return an item, you must first request a Return Merchandise Authorization (or “RMA”) number. To obtain an RMA number, please call to speak with one of our Customer Service Representatives or your Account Representative and provide them with the following information: original invoice number; part number; quantity; reason for the return with as much detail as possible; and any other relevant information that will help us process the return with speed and accuracy. RMA numbers will only be issued to current customers.

                                                      Unauthorized Returns

Items returned to Thunder Diesel & Performance without a valid RMA number will not be processed. Thunder Diesel & Performance will not be responsible for unauthorized returns.

                                                            Restocking Fee

All returns will be subject to a 15%, not to exceed $50.00, restocking fee. Any items which need to be re-boxed will be charged an additional $10.00 re-box fee.



                                               Return Shipping Procedures

Please carefully box the item to be returned and clearly print the RMA number on the outside of the shipping box. Please add the RMA number to the packing slip and place it inside the box. Only return the item(s) listed on the RMA. The item must be shipped to the street address with all shipping costs/duties prepaid. Freight collect shipments will be refused. We can issue a call tag for the return or intercepted shipment, but you will be billed the actual freight plus the $15.00 FedEx call tag fee. Thunder Diesel & Performance is not responsible for lost shipments. The correct address for all returns is:

   Thunder Diesel & Performance   1835 Highway 201 S. Spur   Mountain Home, AR 72653.

                                               Return of Defective Products

Items that do not function correctly or are flawed in a material way are considered defective. Manufacturer policies vary regarding product warranty and handling of defective items. Some defective returns may require manufacturer approval and, in certain cases, the manufacturer may require you to work directly with them to authorize the return. In the event that you purchase a defective item from Thunder Diesel & Performance, the Customer Service Representative will do everything in his or her power to ensure that the item is replaced as quickly as possible, subject to the guidelines of each manufacturer’s policy. Please provide the Customer Service Representative as much detail as possible when requesting an RMA # for a defective item. Defective items will not be subject to the 15% restocking fee.

                                                  Non-Returnable Products

Special order items, replacement parts, items that have been installed, items that were purchased from our “scratch and dent” inventory at a discount, and obsolete or discontinued products are not eligible for returns. All Tuners, South Bend & Valair Clutches, and Titan Tanks are not eligible for return. (See separate section regarding defective products). It is suggested that you state to your customers that they are not returnable on your sales listings, unless you do not mind having them returned to your stock. The packaging used for clutches and fuel tanks make it impossible to present as sellable product if the box has ever been opened.

                                                    Order Cancellations


Thunder Diesel cannot be responsible for order cancellations. Because of the volume and speed of the order processing, it is impossible to stop an order once it has been processed, picked, and put on to one of our shipment trailers. We will attempt to pull it if it has not yet been loaded for shipping. Otherwise it will have to be handled as a return or intercepted shipment, with applicable fees passed along.


                                       Shortage Claims and Shipping Errors

Please carefully inspect all shipments upon receipt. If you have received fewer items than the quantity ordered or a different item from the one ordered, please notify a Thunder Diesel & Performance Customer Service Representative so that we can provide you with the correct item(s) and/or issue an appropriate credit. Any shortage claims or shipping errors must be reported within three days from the receipt of the shipment.

                                       Products Damaged During Shipment

LTL Truck shipments should be inspected at the time of delivery. Any obvious damage to the shipment should be noted on the Bill of Lading. Upon unpacking the shipment, you must make any claim for product damage during shipping directly to the trucking company. For damaged UPS or FedEx shipments, please contact a Thunder Diesel & Performance Customer Service Representative; we will handle the claim on your behalf.


Credits will be issued upon receipt, inspection and approval of the returned items, net of any applicable restocking fees. Please allow 10 business days from the date we receive the returned product to process the RMA and issue the appropriate credit.
