Automotive Control Arms Online

The control arms, or "A arms" as some call them, are an integral part of your vehicle's front suspension. Some vehicles have four, while others have two. The difference is due to the type of suspension system your vehicle features.

How A Control Arm Suspension is Constructed

A control arm suspension system has both upper and lower control arms. The upper control arms connect to the top part of your wheel, while the lower arms are attached to the bottom part. In a strut suspension system, the lower control arms are still employed. However, struts replace the upper control arms.

What OEM Control Arms Do

These allow the arm to swing vertically as the front wheels and tires roll over road hazards. The outer end of a control arm connects via a ball joint. The latter is either permanently attached or pressed or bolted in for easier replacement.
