Important Note for International Buyers

All automotive products sold are for use in the United States (USDM) market only. We cannot guarantee fitment for overseas and international vehicles. Please research prior to purchase to ensure compatibility as we will not be responsible for shipping refunds on orders with these issues.

Return Policy

All return requests must be made within 30 (30) days of the delivery date with documentation related to said purchase as requested. Returns or refunds are only available for products that are returned in the same condition they were sent, brand new and sealed. Returns will NOT be accepted for opened items.

International Buyers - Please Note

Import duties, taxes, and fees aren't included in the item's price or shipping costs. The buyer is responsible for paying for any import fees. Check with your country's customs office to find out what these additional charges will be before you bid or buy.

We utilize USPS, FedEx and UPS for outbound international shipments. If you have a preference in regards to which shipping company we utilize to fulfill your order please make note of it with your payment or in a follow up email. For example, Canadian customers generally prefer USPS as we have heard that FedEx charges additional brokerage fees. On the other hand, many customers from the United Kingdom prefer FedEx as there are no additional fees and they receive their packages significantly faster than those shipped via USPS. Please feel free to contact us for additional information.
