Bi-Metallic Liner process uses a double layer of plating material rather than
one thick layer. This helps the metal bond to the cylinder and makes the
plating more durable. Also, the plating process is more consistent, resulting
in a more precise fit between piston and sleeve for better compression and
longer life.
