To return product, please review our complete return policy below and carefully follow the "How to Return Product" steps to ensure you receive proper credit.

Advance Adapters will accept returns of merchandise in like-new condition within 30 days of the invoice date for full or partial credit of price paid pursuant to the Restocking Fee Policy.  Refunds or credits on merchandise after 30 days is at the discretion of Advance Adapters.  Please note that freight is non-refundable unless the refund is a result of an error on our part (please contact us for prepaid return arrangements).

Refunds will post to the original form of payment if available or by company check by request.  We do not offer store credit. If the original transaction cannot be refunded for any reason, you will receive your refund via company check sent via US Postal Service. 

If your purchase was made with one of our distributers or vendors:
• For a refund- please initiate the return with them.
• For exchanges or warranties- please contact us to see how we can help.  Proof of purchase may be required.

If we receive a return that we cannot process (does not pass inspection, no RGA, arrives damaged from transit), upon request we can ship the part back to the customer (freight will be the customer’s responsibility), or we will dispose of the item after 7 days from notifying the customer.



A 5% processing fee will apply to your credit value for all returns not caused by our error, and additional restocking fees (up to 30%) may be assesed for any of the following:

  • Returned product does not have an RGA code (unauthorized return).  Please contact us to request your RGA as noted in How to Return Product steps. To ensure proper credit is refunded, do not send product without notifying us in advance.
  • Returned product is received more than 30 days from date of original delivery.
  • Returned product is not returned in like-new condition.  All items are assumed to have been delivered in like-new condition unless otherwise reported by end customer within 7 days of order delivery.
  • Return of partial kit (Individual parts will not receive full retail value if purchased in a kit).
  • Return of parts that have been modified, painted, missing 1 or more components listed in description of part contents or damaged due to improper return packaging.
  • Return or exchange of a custom-built unit (Atlas Transfer Cases are considered custom-built). Additional restocking fees may apply for returned custom products.



  • If you believe we have made an error on your order (wrong parts, missing parts, etc.) OR have defective or damaged item(s), please report it to us within 7 days to ensure we can resolve it efficiently.  Issues reported after 7 days may not qualify for prepaid return shipping, no-charge replacement, or waived restocking fee.
  • If you believe your package was damaged or Lost in Transit, please FIRST contact the Freight Carrier immediately to file a claim THEN report the issue to Advance Adapters for assistance.
  • On a Refused Shipment, we reserve the option to recoup our cost for any return freight charges against the value of the refund.  Freight is non-refundable.
