King Shocks 3.75 ID Coil Spring 13" x 500lb

King coil springs are manufactured to our exclusive specifications using the highest quality high-tensile chrome silicon wire in the United States. Our springs are specifically wound for off-road applications, not repurposed from consumer vehicles. Spring rates, wire diameters, and coil lengths have been developed through extensive real-world testing across all types of terrain. Our race-winning designs have been proven in the most demanding environments, from Baja to Dakar. Every spring is end-ground and polished to ensure a flat, stable seat and precise deflection. We offer a wide range of springs to meet your needs. We sell thousands per month with almost no returns, yet we provide an original purchaser lifetime warranty against sagging or breakage. You can rest easy in any eventuality. Should a spring ever fail, we will replace it free of charge, no questions asked. Our customer support is of the same high standard as our product quality and performance. Nothing delivers a ride as comfortable as King products.

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 Confirmation of Compatibility
Since our entire product database is based on North American market (USDM) vehicles, please confirm compatibility with Japanese market (JDM) vehicles before ordering. (If you are unsure whether a listed product fits 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 selecting the year, make, and model using the tabs on our homepage, it does not necessarily guarantee that 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 payment. Shipping estimates are calculated automatically once 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 shipping 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 in 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. All products are transported via air freight. They are not shipped via sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection (Shaken) system," and we are unable to provide strength study documents or similar certifications for this purpose. 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. Because 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, defective products, or items different from your order if you notify us within 7 days of receipt. Furthermore, please note that for products sold through our company, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
