When swapping an S-chassis to an LS engine and T56 transmission, the factory clutch master cylinder is too weak to operate the internal slave cylinder of the LS's large and heavy pressure plate. An upgraded clutch master cylinder is absolutely necessary for an LSX swap.
The ISR kit is a complete kit that includes a brand new clevis, unlike other kits on the market that require you to disassemble and remove the rod and clevis end from the factory master cylinder to use with a Wilwood.
This kit also includes the ISR T56 Remote Clutch Speed Bleeder, which is designed to make bleeding the internal slave/release bearing easy. Most other remote bleeder kits on the market simply attach multiple fittings to the end of a hose, requiring you to zip-tie a loose line in an easy-to-use location. The ISR bleeder utilizes a compact bleeder block designed to mount in the existing spot on an F-body T56 transmission, away from heat sources. It can be easily accessed with a wrench or a vacuum bleeder.

Before Ordering
〇 About Import Consumption Tax
At Shafutoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges other than the total amount paid at checkout.
〇Confirmation of Compatibility
Since all product databases are based on North American vehicles (USDM), please confirm whether or not they can be installed on Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure whether the listed product is compatible with your vehicle. 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 top page, it does not necessarily mean they are compatible with Japanese models 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.
〇 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 automatic shipping calculation 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 order with plenty of time. If you are in a hurry, please inquire about the delivery date in advance. All products are transported by air. They are never shipped by sea freight.
〇 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 System," and we cannot provide strength study documents or similar 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.
〇 Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be damage to the packaging boxes or products due to shipping. Please understand that we will only handle returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Please note that for products sold through us, we will only handle warranty-related support "through us." We do not provide support through other companies or distributors based in Japan.
