A lot of it depends on the length of the springs and equalizers that are used.

When using Leaf Springs # e64SR with the # AP233 Equalizer Kit and the # H248 Hanger Kit, there should be 29-1/2" between the front and center hangers and 29-1/2" between the center and rear hangers. This should achieve a 4-1/2" clearance between the center of the axle and the trailer frame if you have a 3500 lb axle. I've Provided a diagram that should be helpful. I've also provided a link to our trailer maintenance schedule that may come in handy.

With the part # SP-216275 you can use the same dimensions minus 1-1/4 inch in the spacing to accommodate for the shorter spring length.
