The ISR Performance Z33 Differential Bushing replaces the worn-out factory rubber bushings, which are known to tear under hard driving conditions. ISR bushings are rigid and prevent the differential from moving during hard launches and acceleration, reducing wheel hop while improving power transfer to the ground.

Before Ordering
○ About Import Consumption Tax
At the Shaftoya 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.
○ Verification of Compatibility
All of our product databases are based on North American vehicles (USDM), so please verify whether the product can be installed on a Japanese vehicle (JDM) before ordering. (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will check 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 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 the automatically calculated shipping cost differs significantly from 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 check delivery times. Note that all products are transported by air mail. They are not shipped by sea freight.
○ 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 study documents or similar items for that purpose. 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 of your order as soon as it arrives. Since all products are shipped internationally from outside Japan, there may be shipping damage to packaging boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or items different from what was ordered if contacted within 7 days of receipt. Also, for products sold through our company, warranty support will be handled "exclusively through our company." Please note that we do not handle warranty claims through other companies or distributors located in Japan.
