Tomei Forged 8 Countered Stroker Crankshaft - Nissan RB28 Rays Uses an advanced Torque ManagementBy preparing counter weight on every cylinder, making inertia power balance so that bent of the crankshaft is suppressed and vibration and friction is reduced, while the reliability of bearing is raised. Two route oil supply from two journals secures crankpin an enough amount of oil supply. Moreover, X shape oil passage enables supplying oil using the centrifugal force of a crankshaft, reliability of the oil supply at high RPM is improved.
