Connecting rod installation instructions

We have collaborated extensively with the Precision Racing team in Australia to develop and refine the Audi/Lamborghini V10 V2 series of 300M connecting rods. These connecting rods are available exclusively through Precision Racing and cannot be purchased through any other Nitto dealer.

300M material is another step up from your 4340 or 4330 alternatives. It has exceptionally high tensile strength and has excellent resistance under continuous loading and unloading conditions, making it a fantastic material for connecting rods. Much like our 4340 connecting rods, the 300M billets are taken and forged into the shape of a connecting rod in order to ensure you benefit from the uniform material grain flow.

Our V2 connecting rods are our flagship steel connecting rods. In RB30, 2JZ and Barra applications, they have exceeded 2000hp – a clear display of how stout these connecting rods are. The market was crying out for a steel connecting rod that could withstand these power levels and we delivered.

The V2 differs from the regular I-beam in a multitude of ways. Most noticeably, the I-beam pocket has been revised in order to include more material in key areas. The sides of the beam and the pin end are profiled, not straight cut as seen with our H-beams and I-beams, and, the pin bushes have been upgraded to a CHE bush which is made from their proprietary material.

These features culminate in multiple 6 and 7 second drag builds as well as World Time Attack Challenge winners and Roll Racing dominators.
