King Shocks 3.75" ID Coil Spring 18" x 700lb

King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome silicon wire. Our springs are wound specifically for off-road use and are not simply reboxed stock automotive springs. Spring rates, wire diameters, and coil lengths have been developed through real-world testing on all types of terrain. Their race-winning design has been proven in the most grueling battles, from Baja to Dakar. Every spring features closed and ground ends that sit flat to prevent bowing. We boast the largest selection of springs tailored to specific applications. We sell thousands of springs per month with virtually no returns, yet we offer our buyers a lifetime warranty against sagging or breakage, giving you peace of mind in the unlikely event of an issue. If a spring should ever fail, we will gladly replace it, no questions asked. Our customer support is top-tier, just like the quality and performance of our products. Nothing provides a more comfortable ride than King products.

Before Ordering

〇 Regarding Import Consumption Tax
At Shaft-ya Shopping Site, we pay the import consumption tax incurred upon importation on your behalf, so there will be no additional charges beyond the total amount paid at checkout.

〇Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese domestic vehicles (JDM) before placing your order. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle, and 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 sorted by selecting the year, make, and model in the tabs on our homepage, it does not necessarily mean 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. Estimates for shipping costs are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where there is a significant discrepancy between the automatically calculated shipping amount and the actual shipping cost. In such cases, we will contact you individually via email.

All products are generally shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow ample time for 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 mail; they are never shipped via sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are essentially designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength calculation documents or similar paperwork for the Japanese vehicle 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 of your order as soon as it arrives. Since all products are shipped internationally from outside Japan, there may be instances of shipping damage to the packaging or the product itself. Please understand that we will only handle returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Additionally, for products sold through us, all warranty-related matters will be handled "exclusively through our company." Please note that we do not provide support through other companies or distributors located within Japan.
