Connecting rods are forged in I-profile with trapezoidal small ends. They are produced in five different weight classes with regard to the connecting rod's weight at the big end. The big end has a cracked bearing cap, which provides a stable joint in that the bearing cap and connecting rod are secured in the actual fracture surface. The bearing halves are of different materials. The top is of stronger material to withstand high loads. The connecting rod length is 147 mm. Piston pin diameter is 21 mm. Weight (including screws) is 537 g.
