Forged Billet Full Counterweight Crankshaft for 1992-2006 Mitsubishi Evo I-IX by Tomei

The reciprocating motion of the pistons is converted to rotary motion to rotate the wheels. Since the revolution is at high speed, high torsional, bending rigidity and wear resistance of the shaft are also important. Weights are placed on the arms on both sides of the crankpin to increase the balance ratio of the counterweight against the inertia of the piston up-and-down motion and crankpin rotational inertia, thereby reducing vibration and minimizing bending to prevent uneven bearing contact.
