King Shocks 3.75" ID Coil Spring, 17" x 600 lbs

King coil springs are manufactured in the USA to our own specifications using the highest quality high-tensile chrome silicon wire. These springs are not off-the-shelf repackaged items; they are specifically wound for off-road use. Our spring rates, wire diameters, and coil lengths have been developed through extensive field testing across all types of terrain. Our winning racing designs have been proven in the harshest environments from Baja to Dakar. All springs feature closed and ground ends to ensure they sit flat and deflect accurately. We offer a wide range of springs to suit your application. We sell thousands every month with almost no returns, but we provide a lifetime warranty against sagging or breakage to the original purchaser. In the unlikely event that a spring fails, we will gladly replace it without question. Our customer support is as exceptional as the quality and performance of our products, and the experience of riding on King products is second to none.

Before Ordering

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Checking Compatibility
Our entire product database is based on North American vehicles (USDM), so please verify whether parts can be installed on Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether the 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 compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are filtered by year, make, and model using the tabs on our homepage, this does not necessarily mean they will fit Japanese model vehicles without modification.
All product information has 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 cost. In such cases, we will contact you individually via email.

Essentially, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international delivery takes approximately 7 to 14 days, so please allow plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. All products are transported via air freight. We do not use sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
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 structural calculation documents or similar paperwork for this purpose. Therefore, all parts are sold for "use on circuits, private property, and off-road" purposes, and installation and use are at your own risk.

○ Regarding Warranty
Please inspect the contents immediately upon arrival. As all products are shipped internationally from outside of Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defects, or incorrect items if notified 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.
