King Shocks 3.75 ID Coil Spring 13 x 600lb

King coil springs are manufactured in the USA to our own specifications using the highest quality high-tensile chrome silicon wire. Our springs are not off-the-shelf repackaged items; they are specifically wound for off-road use. Spring rates, wire diameters, and coil lengths were developed through extensive real-world testing across all types of terrain. It is a race-winning design proven in brutal battles from Baja to Dakar. All springs feature ground closed ends to sit flat and rebound precisely. We offer the widest selection of springs to suit any application. We sell thousands of springs a month with almost zero returns, yet 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, no questions asked. Our customer support is top-tier, matching the quality and performance of our products. Nothing performs like a King.

Before Ordering

〇 Regarding Import Consumption Tax
At 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 Checking Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese domestic vehicles (JDM) before placing your order. (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 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 using the tabs on our homepage, it does not necessarily guarantee that 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 payment. Shipping estimates will be automatically calculated on the checkout page once you enter your shipping address. For large items such as body parts, there are rare instances where the automatically calculated shipping cost differs 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 about 7 to 14 days, so please allow sufficient time when placing your order. If you are in a hurry, please contact us in advance to check delivery times. Note that all items are transported via air freight; they are not shipped via sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on tracks, private property, or off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please inspect the contents immediately upon arrival. As all products are shipped internationally from outside Japan, packaging boxes and items may occasionally sustain shipping damage. Please understand that we will only provide returns, refunds, or replacement items for damaged, defective, or incorrect products 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 handle correspondence through other companies or distributors located within Japan.
