arm as it moves up and down its range of motion. The up and down motion translates into a circular rotation of the T-Rod arm as it needs to 'twist' around the same arc of movement. OEM silicon filled arms can twist; and so can the spherical bearings of of most aftermarket T-rods. But the ES bushings make no provision to rotate or twist... hence not a good choice.
