The OEM factory bushings are very soft and flexible, allowing the differential to move under hard driving conditions. Additionally, because the factory configuration only includes two front bushings and one rear bushing, the differential can flex excessively as the bushings wear out. This excessive flexing can lead to differential cover failure.
The ISR Performance multi-piece differential bushing kit eliminates unnecessary drivetrain movement and helps prevent damage to the differential cover. The ISR Performance differential bushing kit utilizes a multi-piece design featuring hardened Delrin bushings and aluminum sleeves, and includes a fourth bushing to further reinforce the differential.

Before Ordering
〇 Regarding Import Consumption Tax
At Shafutoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All of our product databases are based on North American vehicles (USDM), so please check the compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will check it 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 on the tabs on our top page, 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 payment. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where there is a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via 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 enough time for your order. 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 not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection (Shaken) system," and we cannot provide strength evaluation documents or similar items for the Japanese vehicle inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, and off-road," 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 packing boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors within Japan.
