leaf spring broken..trailer legs?

Trailer Legs website.
I don't have nor have I ever used them but they look like they would be more work than just using boards. I see they did use boards in the video to raise the axle enough to get the jacks under it.
Also don't see why they would cause any damage to the springs if used.
I would save my money.

If you're talking about hoisting the whole trailer to "stabilize" per the company's claim, it puts no additional load on the springs.

To further that, there is virtually nothing you could do to the trailer in a static situation that would put more stress on the springs than the dynamic loading that is present while underway.

From watching the videos the only way I can see it damaging the springs is if the legs unit is not installed correctly, or placed off center on a spring. Otherwise it appears to do what it was intended to do without damaging anything.

It does apply some different forces from what the suspension was designed for but probably not. Of course, axle manufacturers say not to jack up on the axle tubes.

Bigger question is what do you think you are fixing?

I can't imagine they'd affect the springs negatively. The only issue I see is they're shown supporting the axle inboard of the spring perch/u-bolts, which is contrary to axle mfgrs. requirement not to "jack" on the axles.

So they’re marketing these as not only increased stability when camping, but also as storage devices.
For camping it appears they would literally only be useful on level sites (which I’m sure many are, however I can think of vary few instances where I’ve camped with any RV that a little side to side leveling isn’t required.). So they’re of limited usefulness there.
And the garbage they spew about the advantages for trailer storage sounds like it was cut and pasted out of a late night infomercial with the late Billy Mays!

OP, like many posts you didn’t even begin to explain if your question is out of curiosity or you’ve sustained some damage you think might be attributed to trailer legs. But regardless, they seem like another solution looking for a problem that doesn’t exist.

They appear to provide 3 benefits...
1. They reduce the width between the things in contact with the ground, thus creating a less stable trailer.
2. They raise your trailer up on plastic supports that, when they deteriorate and break, the fall will likely damage your trailer.
3. They separate you from money that could be used for something you need or at least beer.

OK. So really only one benefit for the manufacturer, your money. :)

^Well stated.

Does anyone know if using the product "Trailer Legs" cause/promote broken leaf springs?

I don't see any way they could cause a spring to break.
The Brand maybe new but the lifting devise for one or all axles for working on the suspension or storing the trailer for winter isn't new.
Several similar devices/brands have been around for years that lift the trailer from the axles next to the Ubolts. https://seasense.com/collections/trailering/products/easy-lift-jack

I am leery about putting anything inboard of the spring saddles. As for stability,the only flex they remove is that of the tires. The springs will still flex.
