If you are not having any issues with the trailer bottoming out, and the springs are the same as how they left the factory, then you shouldn't have any issues as some leaf springs are flatter than others depending on the rating of the spring.

With that said when the trailer is loaded you only see roughly 1-1/2" deflection. More than that can mean the trailer has been/is over loaded, or that the springs are worn and are in need of replacement.

If you decide to replace the springs, I will just need to know the axle rating, and length of the spring with the axles off the ground.

Starting with the axle rating, the easiest way to determine this is by looking for the axle tag on the center of the axle. There will be an axle rating on it. If there is not, just send me a picture of the axle tag and I would be happy to help identify the axle.

For spring length you will want to measure from the center of the spring eye to the end of the spring if it is a slipper spring, or from center of spring eye to center of spring eye if it is a double eye spring. I included a few pictures showing the two different measurements for you to take a look at.

With this information I would be happy to recommend the correct replacements should you decide to go that route, and I have linked our selection of leaf springs for you to take a look at.
