King Shocks 3.0 ID Coil Spring 18 x 600lb

King coil springs are manufactured in the USA to our exact specifications using high-quality, high-tensile chrome silicon wire. Our springs are designed exclusively for off-road use, not adapted from commercial automotive springs. Spring rates, wire diameters, and coil lengths have been developed through real-world testing across all types of terrain. This design has proven victorious in grueling races from Baja to Dakar. Every spring is end-closed and ground flat at the base. We offer an extensive lineup. With thousands sold every month and virtually zero returns, we provide a lifetime warranty to the original purchaser against sagging or breakage, giving you peace of mind in the unlikely event of an issue. If a spring fails, we will gladly replace it, no questions asked. We take as much pride in our customer support as we do in the quality and performance of our products. Experience the ride that only King springs can deliver.

Before You Order

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 you will not be charged any additional fees beyond the total amount paid at checkout.

〇 Checking Compatibility
Our entire product database is based on North American market (USDM) vehicles; therefore, please verify compatibility with Japanese market (JDM) vehicles 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 it up 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 via the tabs on our top page, it does not necessarily guarantee that they will fit Japanese market models without modification.
All product descriptions 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. Estimates for shipping fees are calculated automatically when you enter your shipping address on the checkout page. In rare cases, for large items such as body parts, there may be a significant discrepancy between the automatically calculated shipping cost and 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 in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient 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 freight; we do not use sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially all products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese vehicle inspection system," and we are unable to provide strength inspection reports or similar documentation for Japanese inspection purposes. 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 is a possibility of 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. Furthermore, please note that for products sold through our company, all warranty-related support will be handled "exclusively through us." We do not coordinate with other companies or agencies located within Japan.
