Is it Ok to Replace Factory Leaf Springs With a Higher Capacity Option?

Question:
Hello, I have a twin axle travel trailer weighing 5000 lbs. loaded and my leaf springs are rated at 1500 lbs 3 leafs, 26 in. centers. which means they are always loaded at 0ver 80 capacity. I was thinking of changing to 2000 lbs leafs to reduce the load to 60 percent of capacity. I understand that I will have a higher spring rate and that the axles cant take it but wouldnt I gain spring life and less chance of failure? I figure at 60 loading, I am well in the operating range of the heavier spring so the ride shouldnt be that bad. A travel trailer can never be unloaded like a utility trailer so things shouldnt fall apart. Am I making any sense? From your experience, have other trailer owners done this? In general I am not very happy with trailer companies loading components to 80-90 percent capacity by design. It is what it is I guess. Thanks p.s. I have been reading your responces and find it great that you offer advice, keeping safety and regulations in mind.

Though I do tend to warn people about the ride getting stiffer when upping the capacity of their leaf springs, you are correct in that you will technically never be fully "unloaded". I do have to mention that this could still happen, but very minimally.
With that being said, this is something that is done pretty often. Whether this is due to the factory springs not handling the weight very well, or wearing out over time, upgrading to a slightly heavier capacity is perfectly fine. The 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles # e27SR will match your current 26 inch length and will have the single spring capacity of 2,000 pounds. These should eliminate the possibility of bottoming out, and should also extend their longevity.
I don't suggest going with a capacity higher than this, however, as it will most likely cause the trailer to ride poorly.
