King Shocks 3.0 ID Coil Spring 12" x 250lb

King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome-silicon wire. Our springs are not repackaged automotive products; they are specifically wound for off-road use. Spring rates, wire diameters, and coil lengths were developed through extensive field testing across all types of terrain. Their winning design has been proven in the most brutal racing environments, from Baja to Dakar. Every spring is closed and ground at the bottom to ensure they sit flat and deflect accurately. We offer a wide range of springs to suit your specific application. We sell thousands of units per month with almost zero returns, but we provide our buyers with a lifetime warranty against sagging or breakage, so you can have peace of mind in the unlikely event of an issue. If a spring fails, we will gladly replace it, no questions asked. Our customer support is just as top-tier as the quality and performance of our products. Experience the ride that only King products can provide.

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 you will not be charged any additional fees beyond the total amount paid at checkout.

〇 Compatibility Check
Our entire product database is based on North American vehicles (USDM). Please confirm whether the product is compatible with Japanese domestic market (JDM) vehicles 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 sorted by year, manufacturer, and model using 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 Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. In rare cases, for large items such as body parts, there may 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.

Essentially, all products are shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. They are never shipped by sea freight.

○ Regarding Compliance with Japanese Vehicle Inspections (Shaken)
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for these systems. 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 Warranties
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be 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 you contact us within 7 days of receipt. Furthermore, for products sold through us, 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.
