Sonnax turbine hub GM-HT-49HS is a direct replacement for worn or damaged hubs in listed GM converters.
GM 6L90 (captive clutch) converters are known to have two versions of turbine hub. Check the end of the hub towards the stator to determine if you need GM-HT-49HS with the chamfered nose or GM-HT-56HS with the stepped, chamfered nose.
