“It’s all in the details”

Control arms

In this pick-up truck, the control arms in the front suspension were upgraded from 340 MPa yield strength to Docol HR700 LA. This reduces the weight of the control arms by 36%, or 2.7 kg. At the same time, static and dynamic as well as fatigue performance was improved – at a lower cost compared to an aluminum solution.
