King coil springs are manufactured in the USA to rigorous 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 applications. Spring rates, wire diameters, and coil lengths were developed through extensive real-world testing across all types of terrain. This design has proven victorious in grueling races from Baja to Dakar. Every spring is end-ground and polished, ensuring they sit flat and provide precise, consistent rebound. We offer the industry's largest selection of springs to suit your specific application. Despite selling thousands of units monthly with almost no returns, we offer a lifetime warranty against sagging and breakage to original purchasers. Should a failure occur, we will happily replace the product without any questions asked. Our customer support is as outstanding as the quality and performance of our products. We invite you to experience the ride quality unique to King products.


Before You Order

〇 Regarding Import Consumption Tax
At Shaftoya 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.

Compatibility Check
As our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
Please note that if you place an order without confirming compatibility, we cannot accept returns due to fitment issues.
Furthermore, please be aware that even if products are sorted after you select the year, manufacturer, and vehicle model using the tabs on our homepage, it does not necessarily guarantee a direct, bolt-on fit for Japanese market vehicle models.
All product information has been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before placing your order.

〇 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 actual shipping cost may occasionally differ significantly from the amount automatically calculated. In such cases, we will contact you individually via email.

As a rule, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping 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 the estimated delivery date. Please note that all products are transported by air freight. Shipping by sea is not available.

〇 Regarding Japanese Vehicle Inspection (Shaken) Compliance
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 are unable to 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 entirely at your own risk.

〇 Regarding Warranty
Please check the contents immediately upon delivery. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the products themselves. Please understand that we will only provide returns, refunds, or replacement items for products with shipping damage, defective goods, or items different from what was ordered if you notify us within 7 days of receipt. Additionally, please be aware that for products sold through us, warranty support will be handled "exclusively through our company." We do not coordinate with other companies or agencies located within Japan.
