Trailer springs are a type of leaf springs used in trailers and other types of similar vehicles. These leaf springs are of one or several pieces of thin steel leaves, curved to form an arch. Different trailers use variations of this basic structure of trailer spring according to the weight that they usually need to carry.
The thickness of the leaves along with their number plays a significant role in determining the overall level of weight that these leaf springs can handle. The arch of these leaf springs controls the height of these trailers.
