These are very high-quality steel connecting rods.
They are forged / milled from 4340 steel (40CrNiMoA).

The H-profile provides maximum stability at low weight.

This is particularly suitable for high speed 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 CNC milled.
Thus load conditions / stresses can be simulated and the connecting rods can be designed in such a way,
that you have the maximum stiffness at the lowest weight.

During production, all dimensional tolerances are adhered to very precisely and checked several times.

The piston pin bearing is made of bronze and has a bore for lubricating the piston pin.

All our connecting rods are equipped with high-strength Pro-Series 14.9 screws! These have a tensile strength of 1490N/mm^2. Furthermore the threads are rolled which also increases the flank thickness by 30%.

All connecting rods + bearing blocks are marked to each other to avoid confusion during disassembly.

Tolerances:

Piston pin bore: +-4/1000mm
KuWe pin bore: +-4/1000mm
Verticality, parallelism and distortion: +-5/1000mm
Weight among each other: +-1 gram

Use:

- released up to 9000upm
- loadable up to 200PS per connecting rod

These are motor sport articles, the use in the area of the StVO is not permitted.
