Why Are Control Arms Important?
Control arms provide both a connection and pivot point between your vehicle’s suspension and chassis. Typically linking a steering knuckle to the body frame, control arms feature ball joints and bushings which work in tandem to retain correct wheel tracking and position. For example, a lower control arm assists in setting the longitudinal and lateral position of the wheel while the vehicle is in motion. This reduces transmitted noise, road shock and vibration while providing resistance to unwanted suspension movement.
