King Shocks 3.75 ID Coil Spring 20 x 500lb SE

King coil springs are manufactured in the USA to our own specifications using the highest quality high-tensile chrome silicon wire. These are not rebranded automotive springs, but are wound specifically for off-road use. The spring rates, wire diameters, and coil lengths were developed through extensive field testing on all types of terrain. Our race-winning designs have been tested in the harshest environments from Baja to Dakar. Every spring features closed and ground ends to ensure they sit flat and deflect accurately. We offer a wide range of springs to suit your specific application. With thousands sold every month and almost no returns, we offer a lifetime warranty against sagging or breakage to the original purchaser, giving you peace of mind in the unlikely event of an issue. Should a spring fail, we will replace it unconditionally without hesitation. Much like our quality and performance, our customer support is second to none. There is no ride quite 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 on your behalf, so there are no additional charges beyond the total amount paid at checkout.

〇 Checking Compatibility
As 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 order without verifying 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 homepage, this does not necessarily 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 before ordering if you have any questions.

○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your delivery address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount automatically calculated. 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 about 7 to 14 days, so please allow plenty of time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Please note that all items are shipped via air freight; they are never shipped by sea.

○ Regarding Japanese Vehicle Inspection Compliance
Please be aware that all products handled by our company are generally 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 these regulations. 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 Warranties
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we can only handle returns, refunds, or exchanges for shipping damage, defective products, or incorrect items 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 cannot provide support through other companies or agencies located in Japan.
