The clutch master is the “heart” of your hydraulic clutch system. Often they go out or get spongy. This is a high quality replacement clutch master, direct replacement for 75 to 80 Toyota Land Cruiser FJ40, FJ45, or FJ55 and works perfect on earlier as well. We use it on all 80 and earlier models. Has a three bolt flange and bolts on easily. This is a SUPERIOR quality Aisin brand.
