King Shocks 3.75" (approx. 95.3mm) ID Coil Spring 13 x 300lb

King coil springs are manufactured in the United States to our specifications using the highest quality high-tensile chrome silicon wire. Our springs are wound specifically for off-road use, not adapted from mass-produced passenger vehicle springs. Spring rates, wire diameters, and coil lengths have been developed through field testing on all types of terrain. It is a winning design proven in the most grueling race environments from Baja to Dakar. All springs feature flat, ground-closed ends to ensure straight, consistent deflection. We stock a wide range of optimal fitment springs and sell thousands per month with almost zero returns; however, we provide a lifetime warranty against sagging or breakage for the original purchaser. You can use them with 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 as exceptional as the quality and performance of our products. There is no ride quality that surpasses King products.

Before Ordering

〇 Regarding Import Consumption Tax
At Shafutoya 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
Since our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese domestic market (JDM) vehicles before ordering. (If you are unsure if a 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 year, manufacturer, and vehicle model using the tabs on our top page, 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 payment. Estimates for shipping costs are automatically calculated on the checkout page once you enter your shipping address. For large items such as body parts, there are rare cases where there is 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 within Japan, international shipping 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. Note that all products are transported by air. They are never shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation 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 of your package immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packing box or the product itself. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective goods, or items different from your order if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
