Tomei - Forged H-Beam Connecting Rods - VQ35DE (TA203A-NS04A)The connecting rods role is to transfer the compressed pressure that the piston receives to the crankshaft. When the connecting rod becomes one with the piston the connecting rods inertial weight and balance then plays a major factor in the smoothness of the engines rotation assembly and durability at high RPM. The weight factor itself will dramatically change the engines characteristics. The overall strength, balance and light weight properties that
