King coil springs are manufactured to our specifications using the highest quality high-tensile chrome silicon wire available in the United States. These are not rebranded springs for passenger cars; they are wound specifically for off-road use. Spring rate, wire diameter, and coil length were developed through field testing on every type of terrain. It is a race-winning design proven in fierce competitions from Baja to Dakar. All springs are closed-ended and ground flat to ensure stable seating. We offer a wide range of springs to suit your specific application. With thousands sold monthly and almost zero returns, we offer a lifetime warranty against sagging or breakage to the original purchaser, giving you peace of mind in any situation. Should a spring fail, we will gladly replace it, no questions asked. We provide customer support that matches the quality and performance of our products, allowing you to experience the unique ride quality that only King products can offer.


Before Ordering

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.

Compatibility Check
As our product database is primarily based on North American vehicles (USDM), please confirm whether the parts can be installed on Japanese 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 look into it for 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 year, manufacturer, and vehicle model using the tabs on our top page, this 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 checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount automatically calculated. In such cases, we will contact you individually via email.

Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow sufficient time when placing your order. If you are in a hurry, please contact us in advance to check delivery times. Note that all products are transported by air; they are never shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially, all products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation 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.

○ Regarding Warranty
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility of damage to the packaging or the product during transit. Please understand that we will only provide returns, refunds, or replacement products for damaged items, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan for these matters.
