King Shocks 3.0 ID Coil Spring 10 x 400lb

King coil springs are manufactured in the USA to our own proprietary specifications using the highest quality high-tensile chrome silicon wire. Our springs are not off-the-shelf repackaged items; they are specifically wound for off-road use. Spring rates, wire diameters, and coil lengths have been developed through extensive field testing across all types of terrain. Our designs have a proven track record of race victories from Baja to Dakar. All springs have closed and ground ends to ensure they sit flat and deflect accurately. We boast a vast selection of compatible springs and sell thousands per month with almost zero returns, yet we offer our buyers a lifetime warranty against sagging or breakage. It is a guarantee for your peace of mind. Should a spring fail, we will provide a prompt, no-questions-asked replacement. Our support is of the highest standard, rivaling the quality and performance of our products. No other ride compares to King products.

Before You Order

〇 Regarding Import Consumption Tax
At Shafutoya Shopping Site, we cover 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 Confirmation of Compatibility
All product databases are based on North American vehicles (USDM), so please verify whether the product can be installed on a Japanese vehicle (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 selecting the year, manufacturer, and vehicle model via the tabs on our homepage, it does not necessarily guarantee that they will fit a Japanese model vehicle 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 calculated automatically once you enter your delivery address on the checkout page. In rare cases, there may be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost for large items such as body parts. In such cases, we will contact you individually by 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 yourself plenty of 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) Compliance
Basically, all products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese vehicle inspection (Shaken) system," and we cannot provide strength evaluation documents or similar paperwork for that purpose. Therefore, all parts are sold for the purpose of "use on circuits, private land, and off-road" and should be installed and used at your own risk.

○ Regarding Warranties
Please check the contents of your order as soon as it arrives. Because 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, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, we will handle all warranty-related matters "exclusively through our company." Please note that we do not handle matters through other companies or distributors located within Japan.
