Replacement Slipper Spring Recommendation to Replace 31 inch Long Spring

Question:

I have a 1980 Cox, 3 rail motorcycle trailer that has been converted into a flatbed. The springs appear to be replacements are 31inch long, and contain 6 leaves on a 1 1/8inch axle. The ride is stiff and the trailer bounces. I want to replace for a smoother ride while hauling a 900 lbs Harley Davidson.

For a slipper spring that would work well for your application you would want the part # e29SR. This is a 2k rated spring that is 30-1/4 inches long. This should be a much softer spring than what you have as it looks like your spring would be a higher capacity than this one.
