Dual-rate springs and crossover rings are the most cost-effective suspension upgrades. By significantly suppressing body roll and nose dive, the FOX dual-rate spring kit includes everything needed to upgrade your UTV to a true dual-rate setup with crossover adjustment. Using top-grade springs, it maintains consistent performance and prevents sagging from extended use.
Before placing your order
〇 Regarding Import Consumption Tax
At Shaft-ya, we cover the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇 Checking Compatibility
As our entire product database is based on North American vehicles (USDM), please confirm whether parts are compatible with Japanese-spec 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 an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by year, make, and model using the tabs on our homepage, this does not necessarily guarantee a direct, unmodified fit for Japanese-spec vehicles.
All product descriptions have been translated into Japanese using translation software. As there may be confusing phrasing, 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. In rare cases, there may be a significant discrepancy between the automatically calculated shipping cost and the actual cost for large items such as body parts. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. 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 rush, please inquire about delivery times in advance. Note that all items are transported via air freight; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not designed to comply with "Japanese vehicle inspection standards," and we are unable to provide documents such as strength calculation reports for Japanese inspections. Therefore, all parts are sold for "circuit, private property, or off-road use only," and you are responsible for their installation and use at your own risk.
○ Regarding Warranties
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside of Japan, there is a possibility of damage to the shipping box or the product during transit. We will only provide returns, refunds, or exchanges for shipping damage, defective products, or incorrect items if notified within 7 days of receipt. Please understand that for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not facilitate support through other companies or distributors located within Japan.
