2009-2017 STi Direct-Fit 800HP Rear Axles
It has been a long time coming for this set of axles. When the STi was released, many models were pushing past the 600HP mark, and we moved from upgrading axle bars using factory CVs to our Level 5 axle and hub kits. As time has passed, the cars are beginning to age, and with most builds under 800HP, we decided to create a direct bolt-in axle that supports 800WHP.
This is similar to our Level 5 axles in that the outer CV is made from billet chromoly and the internals are made from the same high-grade material, but it uses the original spline size to fit the stock hubs. To ensure the center bar can handle the demands of hard launches, autocross, and rally, we decided to use a new 300M material sourced directly from a Swedish mill (*Ovar). This material has proven to be arguably the strongest and most resilient bar material we have ever used. We also recently changed the inner CV from a tripod design to a full ball-and-cage design and increased the radius of the spline plug for added strength.

Before Ordering
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇 Compatibility Confirmation
As our entire product database is based on North American vehicles (USDM), please confirm whether the item can be installed on Japanese 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 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 a product is sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not necessarily mean it will fit the Japanese model of the vehicle 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 Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself plenty of time when ordering. 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 never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
The products we handle are basically all designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength test reports for Japanese vehicle inspection purposes. 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 immediately upon arrival. As all products are shipped internationally from outside Japan, packaging boxes and products may sustain shipping damage. 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 our company, all warranty-related support will be handled "strictly through us." Please note that we do not handle support through other companies or distributors located within Japan.
