A leaf spring, also known as a leaf spring, is an elastic element made of a number of elastic steel plates stacked on top of each other. It is widely used in truck suspension and vibration damping systems. Compared with traditional coil springs, leaf springs have higher load carrying capacity, better stability and longer service life.
Leaf springs are an integral part of your trailer suspension system. The double-eye spring is suspended at the ends by hangers that attach to its eye or, in the case of tandem-axle or triple-axle systems, into hangers in the front and rear and an equalizer or equalizers in the center. To determine the type of hangers or hanger kit you need, you must know the specific type of leaf spring you have, as well as your axle diameter and capacity. Depending on the hanger kits used with them, springs can be configured to work for single-, tandem- or triple-axle applications.
