Upper Control Arms (UCAs) are considered the first step in a mid-travel truck build, unlocking a vehicle's off-road performance on harsh terrain. Our engineers thoroughly evaluated the suspension geometry and designed UCAs optimized for the target vehicle. Lifting a vehicle affects OEM alignment specifications and results in excessive caster; however, FOX UCAs provide the necessary correction to maintain proper alignment while allowing for increased extension (drop) travel to maximize off-road traction. The added caster reduces wandering at highway speeds and increases driving confidence. You will experience precise, comfortable handling even on rougher roads and trails.
Before Ordering
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Confirmation of Compatibility
Since our entire product database is based on North American specification (USDM) vehicles, please confirm compatibility with Japanese specification (JDM) vehicles before ordering. (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 you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, this does not necessarily mean 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 ordering.
○ Regarding Shipping
Shipping costs are paid at the time of payment. Estimates for shipping costs are automatically calculated once you enter your shipping address on the checkout page. In rare cases, there may be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost for large items such as body parts. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of 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 freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
All products handled by our company are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection (Shaken) system" in any way, and we cannot provide strength study reports or similar documents for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, 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. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacement exchanges for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, regarding products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located in Japan regarding warranty claims.
