King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome silicon wire. These springs are specifically wound for off-road use and are not repurposed automotive springs. Spring rates, wire diameters, and coil lengths have been developed through extensive field testing across diverse terrain. Their winning track record has been proven in harsh race environments from Baja to Dakar. All springs feature closed and ground ends, ensuring they sit flat and deflect accurately. We offer the widest selection of springs to suit your application. With thousands sold monthly and virtually no returns, we provide a lifetime warranty against sagging or breakage to the original purchaser. Should a spring fail, we will gladly replace it unconditionally. In addition to product quality and performance, our customer support is second to none.

Before Ordering

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay 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Compatibility Check
As our entire product database is based on North American (USDM) vehicles, please confirm compatibility with Japanese (JDM) vehicles before placing your order. (If you are unsure whether 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 an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model using the tabs on our top page, this does not necessarily guarantee that 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 calculated automatically once you enter your delivery 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 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 sufficient time for delivery. If you are in a hurry, please contact us in advance to confirm delivery times. Please note that all products are transported by air; sea freight is not used.

○ Regarding Compliance with Japanese Vehicle Inspections
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 are unable to provide strength study documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be cases of shipping damage to the packaging or the product itself. Please understand that for products with shipping damage, defective products, or incorrect items, we will only handle returns, refunds, or exchanges if contacted within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
