Generally speaking, on a single axle trailer you will want the leaf spring hangers to be spaced apart 1/2" less than the eye to eye measurement of your leaf spring. Therefore, you will want to place the hanger 25-1/2" apart on center when using the 4-Leaf Double-Eye Spring part # e77SR with the Single-Axle Trailer Hanger Kit part # APS4.

Please keep in mind that you will need to determine the correct position of your Dexter Trailer Axle part # 20545I-EZ-72-15 before welding the leaf spring hangers to the frame. If you need help with this I have attached an article for you.
