To find the correct replacement leaf spring for your trailer you need to know both the weight rating of your axle and more importantly, the length from center of one eye to the center of the other eye.

For example, the 3-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 23-1/8" Long # e59SR measures 23-1/8 inches from center of one eye to the center of the other eye. Keep in mind that springs can elongate over time so your springs may not be that exact measurement.

For 3,500 lb axles there is also the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 25-1/8" Long # SP-e54SR and 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # SP-210275.

I have added links to video reviews of each of these springs as well as a help article on trailer suspension which I strongly recommend checking out.
