King Shocks 3.75" ID Coil Spring 15" x 600lb

King coil springs are manufactured in the USA using the highest quality, high-tensile chrome silicon wire according to our own specifications. Our springs are not repackaged off-the-shelf automotive parts; they are wound specifically for off-road use. Spring rates, wire diameters, and coil lengths have been developed through real-world testing across all types of terrain. Our race-winning designs have been proven in grueling battles from Baja to Dakar. Every spring features closed, ground ends that sit flat for precise rebound. We boast the most extensive line of springs to suit your application. We sell thousands per month with almost zero returns, but we offer a lifetime warranty against sagging or breakage to the original purchaser. You can use them with peace of mind in any eventuality. Should a spring fail, we will gladly replace it without question. We provide exceptional customer support to match the quality and performance of our products. There is no ride quality that surpasses King products.

Before Ordering

〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred at the time of import 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 market vehicles (USDM), please confirm whether or not parts can be installed on Japanese market 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 sorted by selecting the model year, manufacturer, and vehicle model via the tabs on our home page, this does not necessarily mean they will fit Japanese market 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. 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.

Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. We do not use sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are fundamentally designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength study documents or similar materials for this system. Therefore, all parts are sold for the purpose of "use on circuits, private property, and off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, packaging or products may sustain damage during transit. Please understand that we will only handle returns, refunds, or replacement exchanges for items with transit damage, defective products, or items different from what was ordered 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.
