King Shocks 3.0 ID Coil Spring 16 x 600lb

King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome silicon wire. Our springs are not repackaged off-the-shelf automotive springs; 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. Our race-winning designs have been proven in the toughest battles from Baja to Dakar. Every spring features closed and ground ends to ensure they sit flat and rebound accurately. We offer the largest lineup of springs tailored to your application. We sell thousands of springs per month with almost zero returns, but we provide a lifetime warranty against sagging or breakage to the original purchaser for your peace of mind. In the rare event of a defect, we are happy to replace it, no questions asked. Our customer support is as exceptional as our product quality and performance. Nothing rides like a King.

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 (USDM) vehicles, please confirm whether the products can be installed on Japanese (JDM) vehicles 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 year, make, and model using the tabs on our top 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 payment. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, the automatic shipping calculation may occasionally differ significantly from 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 sufficient time for your order. 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
Basically, all products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection (Shaken) System," and we cannot provide strength evaluation documents 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 inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, packaging and products may occasionally sustain delivery damage. Please understand that we will only provide returns, refunds, or replacements for damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Additionally, regarding products sold through our company, please note that all warranty-related support will be handled "exclusively through us." We do not coordinate with other companies or agencies located within Japan.
