At Wisefab, we are constantly striving 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 are rated for 1500 hp and offer exceptional reliability. The axle shaft is designed to be slightly weaker than the differential output shaft. Our axles utilize high-strength CV joints with minimal wear. As expensive drivetrain components are now commonly used in most rally, drift, and race cars, it is crucial to build a life-extending system between them. The key is a superior shaft material that is not only high in yield strength but also capable of resisting deformation and torsion. Should a drivetrain component fail, the Wisefab shaft will absorb the abuse. Our shafts flex to absorb excessive critical torque. Even in such situations, Wisefab shafts can twist at least 90 degrees—and often up to 180 or even 360 degrees—without failing, allowing you to finish the race successfully. Please note that no torsion occurs until the torque limit is reached. If the shaft has twisted more than 90 degrees, we recommend replacing it.
- Maximum horsepower rating: 1500 hp
- 30 splines on the outer side, 6x94 flange on the inner side
- Length from wheel mounting surface to inner flange: Left: min 524mm, max 570mm; Right: min 559mm, max 605mm
- Maximum CV operating angle: 50 degrees outer / 25 degrees inner
- Maximum permissible permanent shaft flex before replacement: 90 degrees
Before placing your order
〇 Regarding Import Consumption Tax
At the Shaft-ya 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Compatibility Check
Our entire product database is based on North American vehicles (USDM). Please confirm whether the product can be installed on a Japanese domestic vehicle (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate 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 are compatible with Japanese models 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. Estimates for shipping costs are automatically calculated when 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 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 warehouse in the United States. Unlike domestic shipping in Japan, international shipping 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 delivery times. Please note that all products are transported by air; they are not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Products we handle are basically designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork 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 immediately upon arrival of your product. As 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 replacements for products with shipping damage, defective goods, or items different from what was ordered if you contact us within 7 days of receipt. Please note that for products sold through our company, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
