FEATURES: 1/4-28 pilot (SG) crankshaft for Centax type clutch
          Advanced Bi-Metallic Liner. This process uses a double layer of
            plating material rather than one thick layer. This helps the metal
            to bond to the cylinder and is more durable. Also, the plating
            process is more consistent, resulting in a more precise fit between
            piston and sleeve for better compression, longer life.
