King Shocks 3.75" I.D. Coil Spring 20" x 700 lbs

King coil springs are manufactured in the USA to our specifications using the highest quality high-tensile chrome silicon wire. Our springs are specifically wound for off-road applications and are not repurposed automotive springs. The spring rates, wire diameters, and coil lengths were developed through extensive real-world testing across all types of terrain. Our winning designs have been battle-tested in the fiercest races from Baja to Dakar. Every spring features closed and ground ends that sit flat and deflect accurately. We offer one of the largest selections of springs available. Despite selling thousands of springs monthly with almost no returns, we provide a lifetime warranty to the original purchaser against sagging and breakage, giving you peace of mind in the unlikely event of an issue. Should a spring fail, we will replace it unconditionally without hesitation. Our customer support is held to the same high standards as our product quality and performance. Experience the King ride for yourself.

Before You Order

〇 Regarding Import Consumption Tax
At the 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Checking Compatibility
Since our entire product database is based on North American (USDM) vehicles, please confirm whether the products are compatible with Japanese (JDM) vehicles 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 assist you.)
If you order without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are filtered by selecting the year, manufacturer, and vehicle model via the tabs on our top page, it does not guarantee that they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before placing your order.

○ 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 actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually via email.

All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient 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 be aware that all products handled by our company are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural review documents or similar paperwork for this purpose. 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 check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility that packaging or products may sustain damage during transit. Please understand that we will only provide returns, refunds, or exchanges for damaged, defective, or incorrect items if you notify us within 7 days of receipt. Furthermore, please note that for products sold through us, all warranty-related support will be handled "exclusively through us." We do not coordinate with other companies or agencies located within Japan.
