These are very high quality steel connecting rods. These are forged / milled from 4340 steel (40CrNiMoA). The H-profile provides maximum stability at low weight. This is particularly well suited for high revving engines.
Thanks to the forged chrome-nickel steel, our I-connecting rods are significantly more resilient than the series connecting rods. After numerous hardening processes, our connecting rods achieve a hardness of HRC35-38. Finally, the connecting rods were shot peened to further increase the surface density.
Our connecting rods are 3D designed and then CNC milled. This allows load conditions / stresses to be simulated and the connecting rods to be designed to have the maximum stiffness with the least weight.
During production, all dimensional tolerances are very precisely adhered to and checked several times. The piston pin bearing is made of bronze and has a hole for lubrication of the piston pin. To avoid confusion during disassembly, all connecting rods + bearing blocks are marked relative to each other.
Tolerances:
Piston pin bore: +-4/1000mm
KuWe pin bore: +-4/1000mm
Verticality, parallelism and distortion: +-5/1000mm
Weight between them: +-1 gram
Technical data / dimensions:
Material: 4340 steel (40CrNiMoA).
Length : 153mm
