King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome silicon wire. Our springs are not merely repackaged automotive springs; they are specifically wound for off-road use. Spring rates, wire diameters, and coil lengths have been developed through extensive field testing across all types of terrain. These are race-proven designs, tested in the harshest competitive environments from Baja to Dakar. Every spring is end-ground and polished for a stable seat and precise rebound. We offer the largest selection to match your specific needs. Despite selling thousands of springs monthly with almost no returns, we provide a lifetime warranty against sagging or breakage to the original purchaser. You can have peace of mind even in the unlikely event of an issue. Should a spring fail, we will gladly replace it free of charge, no questions asked. We promise the best customer support to match the quality and performance of our products. Nothing rides like a King.


Before Ordering

〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.

〇 Confirmation of Compatibility
Since all of our product databases are based on North American vehicles (USDM), please confirm whether or not they can be installed on Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Furthermore, please note that even if products are sorted by selecting the year, manufacturer, and vehicle model via the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.

○ Regarding Shipping
Shipping costs are paid at the time of payment. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where there is a significant discrepancy between the automatically calculated shipping amount and the actual shipping cost. In such cases, we will contact you individually via email.

All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air. They will not be shipped by sea.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are basically designed and manufactured outside of Japan. They are not adapted to the "Japanese vehicle inspection system" at all, and we cannot provide strength evaluation documents or the like for the Japanese vehicle inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please check the contents of your order as soon as it arrives. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product itself. Please understand that we will only provide returns, refunds, or replacement products for damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Additionally, regarding products sold through us, all warranty-related matters will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
