Description
Arlows 6x Steel Connecting Rod Audi RS4 152,8mm (H-Beam)
Note that the connecting rods are 1.2mm shorter than the stock connecting rods. This results in a compression reduction from 9.0:1 to 8.2:1 which enables the components to better handle higher boost pressures.
Fitting at following Audi V6 engines:
- Audi RS4 2,7L Biturbo
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%.
