The Ford Mustang S550 Rear Upper Control Arms (RUCA) are used for camber adjustment. These arms are constructed from high-strength alloy steel and feature double adjusters that allow for full adjustment without removing the arms. The arms also include lock collars, which eliminate the need for one jam nut. This reduces the risk of them coming loose under heavy stress.
The product includes two fully assembled arms (one left and one right).

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Compatibility Check
As our entire product database is based on North American vehicles (USDM), please confirm whether they can be installed on Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an 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 in 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 before ordering if you have any questions.
○Regarding Shipping
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually by email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, 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 check the delivery time. Please note that all products are transported by air; they are not shipped by sea.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not adapted to the "Japanese Vehicle Inspection System" in any way, and we cannot provide strength evaluation documents or similar documentation for Japanese vehicle inspection purposes. 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 immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please note that for products sold through us, we will only handle warranty-related matters "exclusively through our company." We do not provide support through other companies or distributors located within Japan.
