Not exactly true. They can be oriented many ways, depending on WHAT you're doing. But to increase caster, they should be oriented with the bolt hole in the FRONT bushings facing closest to the frame and with the holes in the REAR bushings facing closest to the ball joint. In this way, you're effectively lengthening the FRONT of the control arm and shortening the REAR, thereby increasing the caster angle. You are shifting the upper ball joint BACK towards the rear of the car. They can also be installed to increase or decrease camber as well.
