240SX S13 S14 1989-1998 Wilwood Clutch Master Cylinder Adapter for LS Swap

Out of stock


When doing a conversion or simply upgrading your clutch master cylinder to a Wilwood option, you will find the PCD is not the same as the OEM S/R chassis'.

The GKTECH Wilwood master cylinder adapter simply allows you to do so while taking up as little room as possible.

This little bad boy measures 6mm thick and also comes with countersunk allen key bolts and a clevis to suit your desired master cylinder. This listing does not include the master cylinder.

We have also included the option of two different master cylinders that we recommend. We suggest double checking the measurements supplied to ensure there are no clearance issues between the master cylinder and the engine.
