Upper Control Arm

Upper Control Arm – Be the Master of Your Suspension

The upper control arm connects to the frame by a control arm shaft. The arm spans out to the spindle or knuckle support and is connected by a ball joint or a pin and bushing. The upper control arm works in unison with the lower control arm, this is called a double wishbone suspension. Control arms typically house wearable suspension parts. The inner part of the control, where it connects to the frame, will often have a shaft with bushings. The outer portion of the control arm will have a replaceable ball joint or an upper outer pin and bushing.
