FAQS：

Q: What should I do if the part number matches the product description, but my vehicle or equipment is not listed in the "Compatible Models" list?
A: Please provide your 17-digit VIN (Vehicle Identification Number) or equipment details (brand, model, year, etc.), along with photos of the old product and the part number you wish to purchase via live chat or message. We will use our database to verify compatibility and assist you in finding the correct part if needed.

Q: What should I do if my vehicle or equipment matches the year, make, model, and engine code in the product description, but there is no matching part number?
A: Please share your 17-digit VIN or equipment details, along with the part number you are interested in, via live chat or message. We will check our database and confirm whether the part is compatible with your vehicle or equipment as soon as possible.

Q: Can I purchase individual parts from a kit instead of the entire kit?
A: Yes, we often sell individual parts from kits separately. If you cannot find the specific part in our store, please send us your vehicle or equipment model and the list of parts you need. We will provide you with relevant links or options.

Q: What should I do if my package is damaged, lost, or has other issues during shipping?
A: While we ensure every item is carefully checked and packaged before shipping, unforeseen issues may occur. If you encounter any shipping-related problems, please contact us via email with a detailed description and relevant pictures (if available). We will work diligently to resolve the issue for you.

Q: Do you offer international shipping, and will I need to pay customs or import fees?
A: Yes, we offer international shipping. Please note that customs duties, taxes, or import fees may apply depending on your country’s regulations. These charges are the buyer’s responsibility and are not included in the product price or shipping cost.

Q: What is your return or exchange policy?
A: If you receive a defective or incorrect item, please contact us within 7 days of delivery with photos or videos of the issue. We will arrange a return or exchange. Due to the nature of automotive and machinery parts, eBay’s compatibility information may not always be 100% accurate. Before initiating a return on eBay, please send us a message so we can work together to find a suitable solution.

Q: What is your warranty policy?
A: We offer a limited warranty on our parts, covering manufacturing defects. The warranty period varies by product and is specified in the product description or can be confirmed by contacting us. Please note that the warranty does not cover damage caused by improper installation, misuse, or normal wear and tear.

Q: What if shipping is not available in my region?
A: We apologize for the inconvenience. The platform’s shipping service may not cover some regions. If your order cannot be shipped to your location, please contact our store for more information. Our service team will explore alternative shipping methods and provide an estimated shipping rate.
