Control arms are among the most important parts of any vehicle. Essentially, it helps to connect the front wheel assembly with the rest of your car's frame. Thus, not only allowing you to steer your vehicle accurately. But, the control arms also bear the brunt of any shock, movement, and load that your wheels absorb while you're driving. When you're in motion, the control arms synchronize the motion between the chassis and the wheels. On top of that, it aids in coordinating the operation of both the suspension and steering systems in your car. This ultimately yields a comfier yet sportier ride, and lets you take better control of the vehicle.
