I've had good luck with Etrailer. But sometimes I've also found better prices when I shopped around. Just depends.
Just a heads-up: if you go to heavier springs, you may need to get longer U-bolts.

FYI, a friend of mine got his springs from etrailer last year and they were stamped Made in China.

So I finally pulled the good spring off... measures out to 25.25 eye to eye. Gonna need new shoulders bolts anyway as those mostly were trashed removing them, I plan on a wet bolt/shackle kit anyway.
The stamping on the spring band was:
RA 93115
7 29 04
I might assume the second number is the date it was stamped
A search does bring back a matching hit:
https://standardaxle.ca/product/spring-25-70-4-leaves-72-26a-sup/
But those are rated at 3K, so, who knows. The number I found on the axle was 5200. The number on the RV is 5080 per axle, so, ha, none of it lines up. Either way I think I'm going with 3K springs.

3K per spring is 6K per axle which is more then 5.2K per axle which is more than 5.02K max load!!!
You should NEVER run at max load anyway.

Yeah, I hear you... I think I'm safe going with more spring, but I agree, the numbers don't line up, and I don't plan to overload it, I just don't want the springs to break again.
It turns out, the RV industry can design their GVWR based pin weight supported... so, GVWR of 12K, with a 2K tongue weight supported by the tow rig means they can legally sell a 12k GVWR RV with tandem 5K axles.
In a way it makes sense, but it still doesn't seem smart to me to be running maxed out all the time. They are 3" axles, as are most 6K axles. AL-KO is the brand.

Stick with the same spring capacity but spend the $$$ for US Made.

And no guarantee that even if it's supposed to be made in America, it won't say Made in China when you actually get it. You're doing what I would be doing.

It turns out, when I search for "93115" springs, they are sometimes 25.25, and sometimes 25.13 (or shown as 25 1/4, I'll assume there is rounding in the first number).
The examples are always 4 leaf springs rated at 3,000 lbs each. They get away with a 4 leaf spring because it has thicker leaves than the 5 leaf springs. I'm not sure if one is really better than the other.
I'm also not 100% sure mine measure out to 25.25, or 25.13, with a tape measure it is easy to be off by a 16th, these maybe fall in the middle somewhere, but they are 19 years old, and maybe at this point we are splitting hairs. The longer length at best adds 1/16 on either end of the spring.
Interestingly enough, you can find a set of 4 on amazon, haha:
4 Leaf Spring Set
They are stupid cheap at $40 a each shipped, so I'm going to assume those are the worst china has to offer.
I'll continue the search to find the best quality, but it is a trick to know what you're even ordering now. It seems dexter/rockwell is still american made, but can't seem to find them to order online.
I need to get this order done today so I can get them in by next weekend.
