The TOMEI Crankshaft is available as Semi-Counter Balanced or Full Counter Balanced. By counter weighing every cylinder, the crankshaft will suppress excess vibration and reduce friction. This increases durability and reduced the chance of engine failure.

Two-route oil supply from two journals ensures enough oil is supplied to the crank. Moreover, the distinct ‘X’ shape oil passage enables oil to be supplied using the centrifugal force of a crankshaft. This increases reliability of the oil supply at higher RPMs.
