Description
Audi Con-Rod Set
Fitting at following Audi 5 cylinder engines:
- Audi 80 90 2,3L
- Audi S2
- Audi RS2
This highquality con-rods are made of 4340 steel (40CrNiMoA).
The H-shank enables maximum stability during minimum weight.
Thereby they're perfectly suited for high-engine-speeds.
At first this con-rods got many times hardened to achieve an durability of HRC35-38.
Finally they got shot-blasted to strenghen the surface density to the maximum.
Before all of our con-rods are 3D designed and finally CNC-milled, it's possible to simulate a lot of charge states and tensions.
The small-end-bearing is made of bronze, and is suited with an lubrication bore.
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%.
