In order to find the correct replacement leaf springs for a trailer you first need to start by noting the type whether that be slipper or double eye. Then, you'll need to measure their unloaded length via jacking up the trailer. If the springs are worn they will measure longer than their replacement. Lastly, you will need to note the axle capacity which is found on the tag in the center of the beam. Please note, the number of leaves does not really denote capacity as leaves have different thicknesses. Once you have all this info you can choose the correct replacement from the list below. The springs should be replaced in pairs as well. The 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles part # e54SR is a pretty common replacement measuring 25-1/8". In regards to u-bolts, I recommend the CE Smith U-Bolt Kit for Mounting 3,500-lb part # CE23002.

Unfortunately, we have no way to look up leaf springs for any one particular trailer.
