While placing your order, we expect customers to have a basic understanding of their vehicle, including its components, model year, and factory-equipped features. Just like when purchasing a vehicle from a dealer or previous owner, you are expected to understand basic information about the vehicle, including its equipment and general configuration, and to be aware of at least some fundamental features and common knowledge. To ensure compatibility, we require your vehicle’s VIN (Vehicle Identification Number), which will be verified through our internal database and official Ford Motorcraft as-built data systems. Orders will only be processed and shipped after we have confirmed that the selected upgrade is fully compatible with your vehicle. In cases of mismatch or unconfirmed compatibility, we will contact you via phone or email to review the order, and may recommend an alternative product or cancel the order upon discussion. Once your order has been verified, prior to shipment, all modules will undergo a final bench test conducted by our professional technicians as the last step before shipping, ensuring that every component is fully functional, properly configured, and free of any defects. This process allows us to maintain a 100% standard of product reliability and performance. As a result, our service eliminates the possibility of receiving a product that does not fit or is incompatible with your vehicle. Since each order is validated and confirmed prior to shipment, all sales are considered final, and we are unable to offer refunds based on compatibility or fitment-related concerns.
