Advanced 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.
