King Shocks 3.75" I.D. Coil Spring 4.5" x 500 lbs.

King coil springs are manufactured to our specifications using the highest quality high-tensile chrome silicon wire in the USA. Our springs are not repackaged automotive springs; they are specifically wound for off-road applications. Spring rates, wire diameters, and coil lengths were developed through extensive field testing on all types of terrain. Our race-winning designs have been proven in the heat of battle, from Baja to Dakar. All springs are closed and ground, ensuring they sit flat and deflect accurately. We offer the largest selection of springs to suit various applications. We sell thousands of springs each month with almost no returns, yet we offer a lifetime warranty against sagging and breakage to the original purchaser. You can use our products with confidence, knowing that in the unlikely event a spring fails, we will gladly replace it for any reason. Our customer support is held to the same high standards as the quality and performance of our products. Experience the exceptional ride of 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Compatibility Confirmation
Our product database is based on North American vehicles (USDM). Please confirm compatibility with Japanese domestic vehicles (JDM) before placing your order. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle; our support team will be happy to assist you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are filtered by selecting the year, make, and model using the tabs on our top page, this does not guarantee 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 automatically calculated on the checkout page once you enter your shipping address. 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 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; they are not shipped by sea.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese vehicle inspection standards," and we are unable to provide strength study documents or similar for these standards. Therefore, all parts are sold for use on "circuits, private land, or off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the products themselves. Please understand that we will only handle returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, all warranty-related matters will be handled "exclusively through us." Please note that we do not facilitate correspondence through other companies or distributors located within Japan.
