King Shocks 3.75" ID Coil Spring 20" x 350 lbs

King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome silicon wire. Our springs are not rebranded automotive springs; they are specifically wound for off-road applications. 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 harsh conditions from Baja to Dakar. All springs are closed-end and ground, ensuring they sit flat and operate straight and smoothly. We offer a wide range of springs for a variety of applications. We sell thousands per month with almost zero returns, but we provide a lifetime warranty against sagging and breakage to the original purchaser. You can use our products with peace of mind knowing we have you covered. In the rare event of a spring failure, we will happily replace it free of charge, no questions asked. Our customer support is at the highest level, matching the quality and performance of our products. Experience the ride that only King products can provide.

Before Ordering

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.

〇 Compatibility Confirmation
Since our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese domestic vehicles (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look it up 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, manufacturer, and vehicle model via the tabs on our home page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions 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 on the checkout page once you enter your shipping address. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually via email.

Essentially, 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 yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported via air freight. They are not shipped via 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 calculation documents or similar paperwork for the Japanese 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 immediately upon arrival of your order. Because 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, defective products, or incorrect items if you contact us within 7 days of receipt. Additionally, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan for these matters.
