Trailer Leaf Springs come in a number of lengths, widths, capacities and styles. Free Length is the distance from the center of 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 Collection 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 for instance.
Please note: All dimensions are nominal and measurements would possibly vary rather.
