On single axle trailers typically you put the hanger spacing right at 1/4 of an inch shorter than the leaf spring length from eye to eye center. So if you were using the leaf spring part # e54SR that you referenced which measures 25-1/8 inches long from eye to eye unloaded the hanger spacing you'd want to use would be 24-7/8 inches. The hanger kit for this leaf spring typically is the part # APS4.
