King Shocks 3.0 ID Coil Spring 8" x 350lb

King coil springs are manufactured to our specifications using the highest quality high-tensile chrome silicon wire in the USA. Our springs are not rebranded automotive springs; they are specifically wound for off-road use. Spring rates, wire diameters, and coil lengths were developed through extensive field testing in all types of terrain. Our race-winning designs have been proven in harsh environments from Baja to Dakar. Every spring is end-closed and ground, ensuring a flat seat and precise deflection. We offer the largest selection of springs to suit your application. We sell thousands of springs a month with almost zero returns, but we offer a lifetime warranty to the original purchaser against sagging or breakage. We have you covered so you can have peace of mind. In the extremely rare event that a spring is defective, we will happily replace it, no questions asked. Our customer support is as top-tier as the quality and performance of our products. There is no ride like King.

Before Ordering

〇 Regarding Import Consumption Tax
At Shaftoya 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.

〇 Checking Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether parts can be installed on Japanese domestic 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 look into it 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 using the tabs on our top page, this does not necessarily mean they will fit Japanese models 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 automatically calculated on the checkout page once you enter your shipping address. For large items such as body parts, there may occasionally be 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 plenty of time for your order to arrive. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. We do not ship by sea freight.

○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for this purpose. 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 inspect the contents immediately upon delivery. As 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 replacements for products with shipping damage, defects, or incorrect items if notified within 7 days of receipt. Also, for products sold through our company, all warranty-related matters will be handled "exclusively through us." Please note that we cannot facilitate coordination through other companies or distributors located within Japan.
