Stock clutch hydraulic throwout bearing for stock-style 3-speed and 4-speed Chevy clutches only. Install simply by replacing one bolt from the front of the transmission with one of the provided studs, then shim to fit. Use 3/4" bore master cylinder.

This bearing is made much smaller than the racing version so that it will fit behind the "thicker" stock style clutches. This redesigned new housing is much cleaner as it has no boss on the body. Plus, this design also has a retainer on it to prevent over extension and seal damage.
