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 car springs, but are specifically wound for off-road applications. Spring rates, wire diameters, and coil lengths were developed through field testing in all types of terrain. Our race-winning designs have been proven in grueling battles from Baja to Dakar. Every spring is end-closed and ground for a flat, precise seating. We carry the largest selection of application-specific springs. We sell thousands of springs every month with almost zero returns, but we offer a lifetime warranty to the original purchaser against sagging or breakage. You can rest assured in the unlikely event of an issue. If a spring fails, we will gladly replace it, no questions asked. Our customer support is top-tier, matching the quality and performance of our products. The King ride is exceptional.


Before Ordering

〇 Regarding Import Consumption Tax
At Shaft-ya 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.

Compatibility Check
As all our product databases are based on North American vehicles (USDM), please confirm the compatibility for Japanese vehicles (JDM) before placing your order. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. 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 year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before ordering.

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

Basically, 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 yourself enough time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are never shipped by sea freight.

○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Please note that all products we handle are basically designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural review documents or similar paperwork for these regulations. Therefore, all parts are sold for use on "circuits, private land, or off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. 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. Please also note that for products sold through our company, we will only handle warranty-related matters "directly through us." We do not provide support through other companies or distributors located within Japan.
