Must be a wording problem. Axles are provided to the RV trailer manufacturer with a maximum load capacity as certified by their manufacturer. The RV trailer manufacturer has the authority to use any load capacity from the top down when certifying the GAWR for their fitment onto the trailer.

In other words, axles provide with 5200# maximum load capacity from their manufacturer are allowed to be derated to 5080# by the RV trailer manufacturer. (Look on the trailer's certification label for GAWR values).

Ok I think I see your thinking now, they are not certifying the axle per say, but the trailer capacity in relationship to the axle(s) used, a gross weight trailer of say 9,500# might use 5,200# axles.
With that sad it does not take away the fact they are 5,200# (axles)this info would be needed for ordering/needing new part(s) (brakes or bearings) for said axle, this is why I said this was false/flawed thinking.

The GAWR (s) reflect what the trailer manufacturer has deemed appropriate for your trailer.

"Only the trailer manufacturer has the authority to certify your trailer axles."

I say that this is false thinking as in my opinion only the axle manufacture can certify the capacity of their axle(s), unless the trailer and axle manufacture are one and the same and in most cases they are not.

So, what did you find? 🙂

Probably tandem 3500# 5 lug axles, or a Dexter 4.4# 6 lug.

Well with:
UVW of 5530#
Dry axle weight of 4630
GVWR of 7000#
15" tires

Probably 3500# axles

Just look at tire side wall MAX Load at MAX PSI rating
Double the tire max load rating and axle will have same or lower rating

Look at the metallized tag on the left near the front.

Crawl underneath and see if there are tags left on the axles. Get the p/n and call KZ or the axle mfr.
