The genuine General Motors plain bearing 93742707 is compatible with selected General Motors vehicles or assemblies. Compatibility depends on shaft diameter, bearing size, application location, and model year. Always verify the part number 93742707 and bearing specification before purchase to ensure correct fitment.
