This product, SR2944-35, is an output flange (side flange) for Winters Performance 10-inch quick-change differentials. In exploded view: #39
This is a replacement part compatible with the Porsche 930-type CV joint, which is standard equipment on quick-change setups.
Side flanges gradually wear down due to mileage, high-load driving, track curb strikes, or contact with other vehicles during racing. This product can be used to refresh worn-out output side flanges or as a spare part.
Quick-change side flanges come in two types: 31-spline or 35-spline. Please confirm that your current side flange is the 35-spline / 930 flange specification before placing your order.
The 31-spline / 930 flange specification side flange can be viewed here.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shaft-ya shopping site, we cover the import consumption tax incurred during import, so there will be no additional charges beyond the total amount paid at checkout.
〇 Compatibility Check
All product databases are based on North American vehicles (USDM). Please confirm whether the 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 verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products are 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 at the checkout page once you enter your shipping address. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automatically calculated amount. In such cases, we will contact you individually by 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 enough time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. All products are transported via air freight. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents for Japanese inspection purposes. Therefore, all parts are sold for use on "circuits, private property, and off-road" purposes, 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, there may be shipping damage to the packaging or the product itself. Please understand that we will only handle returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Additionally, for products sold through our company, we only provide warranty support "exclusively through us." Please note that we do not handle support through other companies or distributors located in Japan.
