King Shocks 3.0 ID Coil Spring 18 x 400lb

King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome silicon wire. Our springs are not rebranded automotive springs, but are wound specifically for off-road use. Spring rates, wire diameters, and coil lengths have been developed through field testing on all types of terrain. Our race-winning designs have been proven in the toughest battles from Baja to Dakar. All springs feature closed and ground ends for stable and precise deflection. We offer one of the largest spring selections to suit your specific application. With thousands sold monthly and almost no returns, we offer a lifetime warranty to the original purchaser against sagging or breakage. In the unlikely event of a failure, we will happily replace it for any reason. Our customer support is just as top-tier as the quality and performance of our products. There is no ride better than one on King products.

Before Placing Your Order

〇Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred upon importation, so there are no additional charges beyond the total amount paid at checkout.

〇Verification of Fitment
Since our entire product database is based on North American vehicles (USDM), please confirm whether parts can be installed on Japanese market vehicles (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 verifying 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 top page, it does not necessarily guarantee that they will fit Japanese market models 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 once you enter your delivery address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually by email.

Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please allow plenty of time when placing your order. If you are in a hurry, please contact us in advance to confirm delivery times. Please note that all products are transported by air; they are never shipped by sea freight.

○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are fundamentally designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese vehicle inspection system" (Shaken), 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 Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, packaging or products may sustain damage during transit. Please understand that for items with shipping damage, defective products, or incorrect items, we will only handle returns, refunds, or exchanges if notified within 7 days of receipt. Furthermore, for products sold through us, all warranty-related matters will be handled "exclusively through us." Please be aware that we do not facilitate processing through other companies or distributors located within Japan.
