King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome silicon wire. Our springs are specially wound exclusively for off-road use and are not re-boxed automotive springs. Spring rates, wire diameters, and coil lengths have been developed through real-world testing on all types of terrain. They are designed to win in the most brutal races, from Baja to Dakar. All springs feature closed and ground ends to ensure they sit flat and rebound accurately. We offer a wide range of applications and sell thousands per month with almost no returns, yet we offer a lifetime warranty to the original purchaser against sagging or breakage. In the unlikely event of a failure, we are happy to provide a replacement for any reason. Our customer support is as high-quality as our product performance. Experience the ride that only King can provide.


Before Ordering

〇Regarding Import Consumption Tax
At Shaft-ya Shopping Site, we cover 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 Confirmation
Since our entire product database is based on North American vehicles (USDM), please confirm the compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product fits 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 fitment issues.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using 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 checkout. Shipping estimates are calculated automatically 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 shipping cost for large items such as body parts. 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 approximately 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm the delivery date. Please note that all products are transported by air; they are never shipped by sea freight.

○Regarding Compliance with Japanese Vehicle Inspection (Shaken)
The products we carry are basically all designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength examination reports 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 immediately upon arrival. As all products are shipped internationally from outside Japan, there may be damage to the packaging or the product due to transit. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
