Product Description

King engine bearings are manufactured to precision finished wall thicknesses. They cannot be resized, nor should their inner working surfaces be scuffed or otherwise altered. The size of each King bearing shell is stamped into its steel back. It is the installer’s responsibility to check each shell and to confirm that it is the size intended for the job.
