STOCK CLUTCH HYDRAULIC THROWOUT BEARINGS

Stock clutch hydraulic throwout bearing for stock style 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 1" master cylinder.

This bearing is made much smaller than the racing version so that it will fit behind the "thicker" stock style clutches. This new design is much cleaner. It has no boss on the body.

AN4 fittings on the feed and the bleed line. Both fittings are tapped inside to accept the bleeder fitting. If you would like an external bleeder, purchase one each of the following: 8352200063, 6174025 and 91031842-4.

This new design also has a retainer on it to prevent over extension and seal damage.
