The trailer leaf springs act as the connection between the axle and the frame. They allow a built-in “give” in the suspension that allows the axle to move up and down without allowing side to side movement. Without a spring, the tires have to absorb the shock from the road and the weight that the trailer is carrying. This would quickly lead to broken components .
