Return Policy

Return for exchange or refund will be allowed only within 30 days from the date of sale. All authorized return merchandise must be unused and in its original saleable packaging. No return or exchange on merchandise that shows signs of having been installed, mounted or damaged will be allowed regardless of who installed the parts or how the damage occurred. You MUST contact MWR for an RMA number before any returns can be made. All returns must be received by MWR within 14 days after the RMA number has been issued. The RMA does not guarantee a replacement or refund; we will inspect and evaluate the returned merchandise for elegibility for return. Returns are subject to a 25% restocking fee. Returns must be sent freight prepaid and insured by you. We are not responsible for merchandise lost in transit, you should always maintain tracking numbers for returned items until return is resolved. Original shipping and handling charges are not refundable. A copy of your invoice must accompany your return along with a written explanation and a phone number where we can reach you. It is the responsibility of the customer/installer to verify the correctness of size and application of the parts before installation. We cannot be held responsible for parts ordered for the wrong application. If a correct part is ordered, but shipped incorrectly, we will cover shipping expenses through approved shipping means and methods. All approved refunds will be paid by either Company Check, Credit Card Credit, or Account Credit, at MWR’s discretion.

Cores sent to MWR must also have an RMA Number so we can credit your account when they arrive.

No returns are allowed on electrical items. No returns or cancellations are permitted custom-order items like specially configured engines or turbo systems. A 50% non-refundable deposit is required for any custom made items.
