Description
VW VR6 connecting rod set ( 6 pieces )
Suitable for all VW VR6 engines
These are very high-quality steel connecting rods.
They are forged / milled from 4340 steel (40CrNiMoA).
Thanks to the forged chrome-nickel steel, our I-connecting rods are much more resilient than the series conrods.
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 connecting rods + bearing blocks are marked to each other to prevent confusion during disassembly.
All our connecting rods are equipped with high-strength Pro-Series 14.9 3/8" screws ! These have a tensile strength of 1490N/mm^2. Furthermore the threads are rolled which also increases the flank thickness by 30%.

Piston pin bore: +-6/1000mm
KuWe pin bore: +-6/1000mm
Verticality, parallelism and distortion: +-8/1000mm
Weight among each other: +-1 gram
