Wisefab dynamic half-shaft axles are rated for 1500 hp and offer superior reliability. Our axles use low-friction, high-strength CV joints. The key is an excellent shaft material that not only has high yield strength but can also withstand deformation and twisting.
The S-chassis half-shaft kit includes two fully assembled axles and two custom 30-spline hubs that fit OEM S-chassis wheel bearings. The inner flange has a 6x94mm (6x3.7-inch) bolt pattern that fits Winters 930 CV joint flanges.
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 hold 1500 hp and offer superior reliability. The axle shaft strength is designed to be slightly lower than that of the differential output shaft. Our axles use low-wear, high-strength CV joints. As expensive drivetrain components are becoming common in most rally, drift, and race cars, it is crucial to build a life-extending system between them. The key is an excellent shaft material that not only has high yield strength but can also withstand deformation and twisting. If any part of the drivetrain fails, Wisefab shafts will withstand the abuse. Our shafts will bend to absorb excess critical torque. Even in such situations, a Wisefab shaft can twist at least 90 degrees, and often 180 or even 360 degrees without failing, allowing you to finish the race safely. Note that no twisting occurs until the torque limit is reached. If the shaft has twisted more than 90 degrees, we recommend replacing it.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shafutoya 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Confirmation of Compatibility
Since all of our product databases are based on North American vehicles (USDM), please confirm whether or not parts can be installed on Japanese vehicles (JDM) before ordering. (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 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 homepage, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping within 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 Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation 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-public roads," 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 packing box or the product itself. We will only provide returns, refunds, or replacement exchanges if you notify us within 7 days of receipt regarding products with shipping damage, defective products, or products different from your order. Please note that for products sold through us, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
