At Wisefab, we constantly strive to develop the best products that allow drivers to push their limits on the track. Countless hours of research, problem-solving, and meticulous development have gone into our unique designs. Wisefab dynamic half-shaft axles can handle 1500 hp and offer excellent reliability. The axle shaft strength is designed to be slightly lower than that of the differential output shaft. Our axles utilize CV joints with low wear and high strength. Since expensive drivetrain components are now commonly used in most rally cars, drift cars, and race cars, it is crucial to build a life-extending system between them. The key is superior shaft material that is not only high in yield strength but also capable of resisting deformation and torsion. If a component in the drivetrain breaks, the Wisefab shaft withstands the abuse. Our shafts flex to absorb exceeding critical torque. Even in such situations, a Wisefab shaft can twist at least 90 degrees—often reaching 180 or even 360 degrees without failure—allowing you to finish the race safely. Please note that no twisting occurs until the torque limit is reached. If the shaft has twisted beyond 90 degrees, we recommend replacing it.

Before Ordering
〇Regarding Import Consumption Tax
At the Shafutoya shopping site, we cover 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 Check
Our entire product database is primarily based on North American vehicles (USDM). Please confirm whether or not parts can be installed on Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to assist 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, make, and model using the tabs on our homepage, it 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 checkout. Shipping estimates are calculated automatically once 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 cost. 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 yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to check lead times. All products are transported via air freight; they are never shipped via sea freight.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please understand that they do not comply with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents for the purpose of such inspections. 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 of your products. As all products are shipped internationally from outside Japan, there may be shipping damage to the packing boxes or the products themselves. Please understand that we will only handle returns, refunds, or replacements for shipping-damaged items, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, warranty-related support will be provided "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
