Shipping & Returns
Returns Policy
If you are not satisfied with any purchase made with Ace Performance, notify us within thirty-six (36) hours of receiving the package. Items may only be returned if they differ from what you ordered (ie. we shipped the wrong part to you) or you suspect there may be a defect with an item. Fitment issues (ie. you ordered the wrong part) are not a valid reason to return an item, and no refund requests due to fitment issues will be honored. To return an item incorrectly shipped to you, or that you believe to be defective, you must obtain a Return Merchandise Authorization Number (RMA #). The goods must be returned within ten (10) days in the same condition and in the original packaging. If the merchandise is damaged, or not in the original packaging, or no valid RMA # appears on the outside packaging, no refund will be forthcoming and you own the original purchase. The customer will be responsible for all shipping charges.
Electronic items are subject to engineering inspection prior to a refund being issued. All electronic items are carefully tested and inspected prior to sale. All items sold by Ace Performance are new unless otherwise specified.
