In order to pick out replacement leaf springs for your trailer you will need to determine the axle's weight capacity and measure the length and width of your existing leaf spring stack.
If the main info tag/plate is missing from the trailer and you can't find any identifiable info on the axle then your best route for verifying its capacity is by simply contacting the trailer manufacturer. Just have your VIN ready and they will be able to look up its exact specs.
Once you have the capacity needed it's just a matter of measuring your current springs. If you have double-eye springs you will measure from the center of one eye to the center of the other. If you have slipper springs measure from the center of the eye to the end of the leaf on the opposite end. Make sure to measure the leaf springs without any weight on them, either by jacking the trailer up or completely removing the stack.
Since leaf springs tend to stretch out just a bit over time you will want to pick out a new set that matches the length you measured or is just a tad shorter.
If you can tell me what numbers you came up with I will be happy to make a specific recommendation. In the meantime I have attached a link that will take you to our complete selection along with a couple articles you might find helpful.
