The function of the complete rod on the vehicle can be described as long tie-rod and short tie-rod in the systems that are defined as rigid axle system.

Long tie-rod
Long tie-rod transmits the actions transmitted by short tie-rod to the axle located on the other side. Long tie-road connected to selector lever and right/left rods transmits the action of selector level to the rods. It is used for transmission of steering actions to the front wheels and for optimum handling. Long tie-rod provides a precise direction and secure driving. A centrally located part allows for optimal adjustment of both wheels.

Short tie rod
Short tie rod directs the steering action initiated in the steering gearbox, finally transmitting action of steering arm to the wheel. Short tie rot connects the joint to the gooseneck. It acts like a joint which transmits left or right action of selector lever backwards and forwards.
