The description in the picture is wrong for a Mopar suspension. When you turn the adjusting bolt, the lower control arm moves. Not the hex. No tension is added to the bar. Not on a Mopar system anyway, I'm not familiar enough with the design of the Chevy system to say what that one does.
But on the Mopar suspension, when you turn the adjusting bolt it doesn't move the hex, it just changes the angle between the hex and the LCA. Grab an LCA and see for yourself. The bar only twists when the weight of the car moves the LCA and the adjusting lever together. Moving the adjuster just sets the angle between the two.
