King coil springs are manufactured in the USA to our own specifications using the highest quality high-tensile chrome silicon wire. Our springs are not repurposed automotive springs, but are wound specifically for off-road use. Spring rates, wire diameters, and coil lengths have been developed through field testing in all types of terrain. Our race-winning designs have been proven in the toughest battles, from Baja to Dakar. All springs are ground closed and finished to sit flat and deflect accurately. We offer a wide range of springs to suit your specific application. While we sell thousands each month with almost no returns, we offer a lifetime warranty to the original purchaser against sagging or breakage, giving you peace of mind in the unlikely event of an issue. Should a spring be defective, we are happy to replace it, no questions asked. Our customer support is as top-tier as the quality and performance of our products. Don't ride without King.


Before Ordering

〇 Regarding Import Consumption Tax
At the Shafutoya shopping site, we cover the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.

〇Confirmation of Compatibility
Our entire product database is based on North American market vehicles (USDM), so please confirm compatibility with Japanese domestic vehicles (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us, and our support team will be happy to assist you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the model year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily guarantee that 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 calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually via email.

All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international delivery takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are transported by air; they are never shipped by sea freight.

○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength inspection documents or similar paperwork for these regulations. 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.

○ Regarding Warranty
Please check the contents of your order as soon as it arrives. Because all products are shipped internationally from outside Japan, there is a possibility that packaging or products may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacement products for damaged, defective, or incorrect items if notified within 7 days of receipt. Additionally, please note that for products sold through our company, all warranty-related matters will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
