The Sikky S13 240sx Quick Change Subframe Kit is a crucial addition when building a race car that performs at the highest level. This setup allows users to change gear ratios in under 5 minutes simply by removing the rear cover. This is a major advantage when fine-tuning your setup at the track to ensure your gearing is in the sweet spot and you aren't forced to shift at improper times. It is also designed to handle massive amounts of power. Customers have used this setup in cars with well over 1,200 horsepower.
We have designed, developed, and tested our subframe kit to withstand the most grueling conditions. We use advanced technology, such as FARO 3D scanning arms and Solidworks CAD software, to design and build all subframe assemblies to precise tolerances. Perfect rear alignment ensures the differential is always centered to achieve optimal CV joint angles while remaining Formula Drift legal. It is engineered to handle all the abuse that high-horsepower cars dish out. The subframe ships fully assembled with all necessary brackets welded on and the entire assembly powder-coated black. There are options to add a Sikky Winters IRS rear, Sikky solid subframe bushings, driveshafts, and/or heavy-duty axles. If you want to gain an edge over the competition, the Sikky Winters IRS Subframe Kit is your best choice.

Before Ordering
〇Regarding Import Duties and Taxes
At the Shaftoya shopping site, we cover the import duties and taxes incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Since all product databases are based on North American vehicles (USDM), please confirm whether 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 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 model from 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 automatically calculated once 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.
All products are generally shipped internationally from our U.S. 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 the delivery date. Please note that all products are transported by air freight; they are not shipped by sea freight.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese vehicle inspection standards," and we cannot provide structural calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.
○Regarding Warranty
Please check the contents immediately upon arrival of your product. Since all products are shipped internationally from outside Japan, there may be delivery damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for items with delivery damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Please note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
