King Shocks 3.0 ID Coil Spring 10 x 500lb

King coil springs are manufactured to our specifications using the highest quality high-tensile chrome silicon wire in the United States. Our springs are not rebadged passenger car springs; they are wound specifically for off-road use. Spring rates, wire diameters, and coil lengths have been developed through extensive field testing in all types of terrain. Our winning designs have been proven in the harshest racing environments from Baja to Dakar. All springs feature ground, closed ends to ensure they sit flat and deflect accurately. We boast the most extensive selection of springs to suit your application. We sell thousands of units per month with almost zero returns, yet we provide a lifetime warranty against sagging or breakage to the original purchaser, giving you peace of mind in any eventuality. In the rare case of a spring failure, we will gladly replace it, no questions asked. Our customer support is as unparalleled as the quality and performance of our products. Nothing rides like a King.

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

〇 Confirmation of Compatibility
As our entire product database is based on North American vehicles (USDM), please confirm the compatibility for Japanese vehicles (JDM) before placing your order. (If you are unsure if the 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 via the tabs on our homepage, it does not necessarily mean they will fit Japanese model vehicles 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 checkout. Shipping estimates are automatically calculated once you enter your shipping address on the checkout page. 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.

Basically, 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. 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 by sea.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for this purpose. Therefore, all parts are sold for "circuit, private property, or off-road use," 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 box or the product itself. Please understand that we will only provide returns, refunds, or replacement products for damaged items, defective goods, or items different from your order if you contact us within 7 days of receipt. Please also note that for products sold through us, all warranty-related support will be handled "exclusively through our company." Support through other companies or distributors located in Japan is not provided.
