Upper Arm

Upper control arms are important components of a vehicle’s suspension system. They connect the wheel hub to the vehicle’s frame or chassis. Their main function is to control the movement of the wheels during driving. Upper control arms help keep the tires properly aligned with the road. They also support smooth steering and stable handling. These parts usually work together with lower control arms and ball joints. Most upper control arms are made from strong steel or aluminum for durability. Over time they may wear out and require replacement. Properly functioning upper control arms improve vehicle safety, comfort, and overall performance.
