What function does the low arm serve in a McPherson strut suspension system?

In a McPherson strut suspension system, the low arm, often referred to as the lower control arm, plays a crucial role in supporting the weight of the vehicle and absorbing shock. This component connects the vehicle's chassis to the wheel assembly, ensuring that the wheels remain properly aligned with the chassis during various driving conditions. By providing a sturdy connection and allowing for vertical movement, the low arm helps to maintain stability by managing the vehicle's weight distribution and enabling the suspension system to absorb impacts from road irregularities. This function is essential for ride comfort and vehicle handling, making it a fundamental aspect of suspension design in vehicles utilizing a McPherson strut arrangement.
