Shipping estimates are calculated automatically by entering your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually via email.\u003cbr\u003e\u003cbr\u003eBasically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow sufficient time for delivery.

Note that all products are transported by air; they are not shipped by sea.\u003cbr\u003e\u003cbr\u003e○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)\u003cbr\u003ePlease note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the \"Japanese Vehicle Inspection System,\" and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of \"use on circuits, private property, or off-road,\" and installation and use are at your own risk.\u003cbr\u003e\u003cbr\u003e○ Regarding Warranty\u003cbr\u003ePlease check the contents of your package immediately upon arrival. Since all products are shipped internationally from outside Japan, packaging boxes and products may sustain shipping damage. We will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding damaged, defective, or incorrect items. Please understand that for products sold through us, warranty support is handled \"exclusively through us.\" We do not provide support through other companies or distributors located within Japan.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-end=\"688\" data-start=\"631\"\u003e\u003cbr\u003e\u003cstrong data-end=\"772\" data-start=\"752\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003c!----\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Winters Quick Change","offers":[{"title":"Default Title","offer_id":41972363427895,"sku":"WPP-8520A","price":965.0,"currency_code":"CNY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0259\/7502\/9815\/files\/WIN8520A.webp?v=1762224237","url":"https:\/\/fivesquareusa.com\/en-cn\/products\/winters-quick-change-10-spline-quick-change-gears-8520a","provider":"Shaft Shop","version":"1.0","type":"link"}
