At Wisefab, we strive to develop the best products that allow drivers to push their limits on the track. Behind our unique designs lie countless hours of research, problem-solving, and meticulous development. Wisefab dynamic half-shaft axles can handle 1500 hp and offer superior reliability. The strength of our axle shafts is designed to be slightly lower than that of the differential output shafts. Our axles use CV joints with low wear and high strength. Since expensive drivetrain components are now commonly used in most rally, drift, and race cars, it is crucial to build systems that extend the lifespan of these components. The key is an excellent shaft material that is not only high in yield strength but also resistant to deformation and twisting. If other parts of the drivetrain fail, the Wisefab shaft will endure the abuse. Our shafts bend to absorb excessive critical torque. In such situations, Wisefab shafts can twist at least 90 degrees—and often 180 or even 360 degrees—without failing, allowing you to finish the race safely. Please note that no twisting occurs until the torque limit is reached. We recommend replacing the shaft if it has twisted more than 90 degrees.

Before placing your order
〇 Regarding import consumption tax
At Shafutoya, we cover the import consumption tax incurred at the time of import on behalf of the customer, so there are no additional charges beyond the total amount paid at checkout.
〇 Checking compatibility
Our entire product database is based on North American vehicle specifications (USDM). Please check whether parts can be installed on Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether a 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 an order is placed without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and model using the tabs on our top page, it does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All product descriptions 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 once you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may rarely differ significantly from the automated calculation. 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 delivery takes about 7 to 14 days, so please allow plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all items are shipped by air; they are never shipped by sea freight.
○ Regarding Japanese vehicle inspection (Shaken) compliance
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" (Shaken), and we cannot provide strength evaluation documents or similar paperwork for these purposes. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use only," and installation and use are at your own risk.
○ Regarding warranty
Please inspect the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be instances of delivery damage to packaging boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacement products for items that arrive damaged, are defective, or differ from your order if you notify us within 7 days of receipt. Furthermore, for products sold through us, warranty support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
