King Shocks 3.0 ID Coil Spring 12" x 400lb

King coil springs are manufactured in the U.S. to our specifications using the highest quality high-tensile chrome silicon wire. Our springs are not repackaged consumer 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 diverse terrain. Our race-proven designs have been tested under the most grueling conditions, from Baja to Dakar. All springs feature ground ends to ensure they seat flat and rebound accurately. We offer the largest selection of springs for any given application and have sold thousands per month with almost zero returns. Even so, we offer a lifetime warranty to the original purchaser against sagging or breakage. Should a failure occur, we will replace the item unconditionally and without hesitation. Our customer support is just as excellent as the quality and performance of our products. Once you ride on King products, you will feel the difference.

Before You Order

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 Fitment
All of our product databases are based on North American vehicles (USDM). Please confirm whether or not the product can be installed on a Japanese domestic 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 look into it for you.)
If you place an order without confirming fitment, 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, this 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.

All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow yourself sufficient time when placing your order. If you are in a hurry, please contact us to check delivery times in advance. Note that all items are shipped via air freight. We do not use sea freight.

○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for the Japanese inspection system. 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 Warranties
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that for products with shipping damage, defective items, or items different from what was ordered, we will only provide returns, refunds, or exchanges if contacted within 7 days of receipt. Please also 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.
