Trailer Leaf Springs come in quite a lot of lengths, widths, capacities and styles. Free Length is the distance from the center of each and every mounting hole on a double eye spring, or from the mounting hole to the tip of the radius end on a slipper spring. The Selection of Leaves refers back to the total sections of spring material that make up the spring assembly. Free Arch is measured from the center line of the mounting holes to the center of the highest surface of the primary leaf with out a load applied to the spring. Capacity is measured per spring so two 1,750 pound springs would be used on a 3,500 pound axle as an example.
Please note: All dimensions are nominal and measurements might vary relatively.
