What is the size and weight capacity of your axle? When you choose leaf springs their width needs to fit between the hangers on your trailer frame and then they need to be rated for at least the weight of your axle, if not more. You also need to make sure that the length is appropriate for the space between your hangers as well.

For example, the leaf spring # e54SR measures 25-1/8" from center eye to center eye, has a width of 1-3/4", and is rated for a 3,500 lb axle.
