King Shocks 3.0 ID Coil Spring 10 x 150lb

King coil springs are manufactured to our own proprietary specifications using the highest quality high-tensile chrome silicon wire available in the United States. These springs are specifically wound for off-road applications and are not repackaged versions of automotive aftermarket products. Spring rate, wire diameter, and coil length have all been developed through real-world testing across all types of terrain. It is a winning design proven in races from Baja to Dakar. All springs feature closed and ground ends to ensure they sit flat and compress straight. We offer the industry's widest variety of springs to suit your application. We sell thousands of units monthly with almost zero returns, but we provide a lifetime warranty for the original purchaser against sagging or breakage. Our customers can use our products with peace of mind knowing they are fully protected. Should a spring ever fail, we will provide a quick and friendly replacement. In addition to product quality and performance, our customer support is also top-tier. There is no ride quality that surpasses King springs.

Before Ordering

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay 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 Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether the products can be installed on Japanese vehicles (JDM) 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 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 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 automatically calculated when 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.

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 the delivery date. Please note that all products are transported by air. We do not ship by sea freight.

○ Regarding Japanese Vehicle Inspection Compatibility
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 are unable to provide strength analysis reports or similar documentation for Japanese vehicle inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please check the contents of your package immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the products themselves. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if notified within 7 days of receipt. Please note that for products sold through our company, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
