King Shocks 3.0 ID Coil Spring 12" x 450lb

King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome silicon wire. They are specifically wound for off-road applications and are not repurposed automotive springs. Spring rates, wire diameters, and coil lengths have been developed through real-world testing on all types of terrain. Our race-winning designs have been proven in the toughest battles from Baja to Dakar. Every spring features closed, ground ends that sit flat for precise rebound force. We offer the largest selection of springs tailored to your application. We sell thousands of springs each month with almost no returns, but we offer a lifetime warranty against sagging or breakage to original purchasers for your peace of mind. Should a spring ever fail, we will gladly replace it, no questions asked. We are as confident in our exceptional customer support as we are in the quality and performance of our products. Experience the King ride for yourself.

Before You Order

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 are no additional charges beyond the total amount paid at checkout.

〇Compatibility Check
As our entire product database is based on North American vehicles (USDM), please confirm whether the product can be installed on a Japanese vehicle (JDM) before placing your order. (Please feel free to contact us if you are unsure whether the listed product is compatible with your vehicle; 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 from the tabs on our homepage, it does not necessarily guarantee that 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 calculated automatically when 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.

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 sufficient time for your order. If you are in a hurry, please contact us in advance to confirm the delivery time. Please note that all products are transported by air; they are not shipped by sea freight.

○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
In principle, all products we handle are designed and manufactured outside of Japan. Please note that they are not designed to comply with "Japanese vehicle inspection standards," and we cannot provide structural strength calculation documents or similar paperwork for these standards. 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 check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. Please understand that we will only provide returns, refunds, or replacement products for shipping damage, 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, warranty support will be handled "exclusively through our company." Please be aware that we do not coordinate with other companies or agencies located within Japan regarding warranty claims.
