Control arms are a crucial part of a vehicle's suspension system. They are typically mounted between the steering knuckle or spindle and the frame or body of the vehicle, and they help to connect the wheel hub assembly to the suspension system. The primary role of control arms is to help control the motion of the wheels, while also allowing for some degree of movement and flexibility.

​

Control arms help to ensure that the wheels stay properly aligned and perpendicular to the road surface, even when the vehicle encounters bumps, potholes, or other obstacles. They also help to absorb and dampen the shocks and vibrations that are created as the vehicle travels over uneven terrain.

​

In addition to providing stability and control, control arms also help to distribute the weight of the vehicle evenly across the suspension system. This can help to improve handling, reduce wear and tear on the tires and other suspension components, and improve overall vehicle performance and safety.
