Location: Elk River, Minnesota | Hiya,
I'm not sure that this type of spring is something you would first have room for, and second, I don't believe the trailer frame would be built to accommodate the spring as well.
I would be more apt to replace the current springs with a heavier set to deal with this type of issue.
Many times when a really good deal comes around on a new rig, there are two major areas the dealer will "skimp" on....the trailer, and the outboard. The outboard will not be put on as a maximum Horsepower. May times, it can be well below that. The same thing happens with the trailer, and I believe many out there overlook the trailer itself. Many dealers will put the smallest trailer under the rig to get the best possible price point to sell...but that causes issues as some trailers are almost maxed out on their capacity once you put the boat, motor and gas in....leaving very little room for anything extra, let alone then travel down a road that is not optimum. So...the trailer bounds along just fine, but due to being close to max weight, the springs take a beating as they are constantly being flexed more than a heavier trailer would. The result...more flexing = more fatigue, and over time, they wear out and break due to the stress... It is inevitable with any leaf spring combination, but on a trailer that is really close to maximum capacity, it will happen faster.
This may be your case here...or it may not be....as I do not know any more specs on the trailer. Do you have a model number for it?
If you can....I'd get heavier springs if you can find a set that matches the mounting brackets of your trailer. It may even mean replacing your axle as well to a beefier one to accommodate the new springs, etc.
