King Shocks 3.0 ID Coil Spring 12" x 300lb

King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome silicon steel wire. Our springs are not repackaged off-the-shelf automotive springs; they are specifically wound for off-road applications. Spring rates, wire diameters, and coil lengths have been developed through extensive field testing across all types of terrain. Our race-proven designs have demonstrated their performance in fierce competition from Baja to Dakar. Every spring features closed, ground ends to ensure a flat seat and precise deflection. We offer one of the largest selections of springs to suit your specific application. We sell thousands of springs each month with almost zero returns, yet we provide a lifetime warranty against sagging and breakage to the original purchaser, so you can use them with peace of mind. In the unlikely event that a spring breaks, we will gladly replace it, no questions asked. Our customer support is held to the same high standards as the quality and performance of our products. Ride on King products and you will feel the difference.

Before Placing Your Order

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

〇 Confirmation of Compatibility
Since our entire product database is based on North American specification vehicles (USDM), please verify whether the products can be installed on Japanese specification vehicles (JDM) before placing your order. (If you are unsure if a 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 filtered by year, manufacturer, and vehicle model using the tabs on our homepage, 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 if you have any questions before ordering.

○ 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. For large items such as body parts, there are rare cases where there is a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.

In principle, 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 delivery times. Note that all products are transported via air freight; they are not shipped via 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 cannot provide structural analysis 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 delivery of your product. 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 if you contact us within 7 days of receipt regarding products with shipping damage, defective items, or items different from your order. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
