When I ordered my axles from Colin Hyde, he explained that there is a difference in the rubber inside the axles. Derated axles have less of it, which is what makes them softer riding for lighter trailers.
The other option being discussed makes no sense... If the only change was a different label with a different rating, the axles would bounce lighter trailers to pieces in no time at all. It's as bad to have too much axle as it is to have too little.

It is your trailer, do what you want.
Airstream ordered the axle that way. I assume your axle has a label to that effect. But it is your trailer not mine.
https://www.dexteraxle.com/Resources...-an-axle-label
You have had a conversation with Dexter and you posted that they told you the axles are derated for capacity.
Dexter's website shows that it is possible to get load capacitys in different ratings in 100 pound increments.
How do you think they change the axle capacity? With a sticker?
If a sticker makes a difference, why not just make one axle and then chnage the sticker for all load capacities?
As to car and light truck suspension packages, I am very familar. I worked for an automobile manufacturer some time ago and for a number of dealerships. The designed suspension capacity and load capacity is not done with a sticker. Each GVWR is a different spring package. In some vehicles the original springs vary with the weight of options. But this is way off topic.
Make contact with Dexter or a Dexter distributor not me. They are the experts. They make them or the distributor sells them. You seem to question anything that is in this thread. Go find it for yourself. Contact the company or distributor that handles the product. I don't make axles or stickers so I am not a source.

Ugg, I don't need axles..yet. And I'm not taking any position. I have questions relative to what I was told vs. age old, often repeated internet postings...which make nothing actually true. I'm just looking for facts. My label is coded. That's why I called dexter in the first place. I see where Rockwell states the 100# increments. But what does that really mean? I didn't see it on the dexter site. Their literature breaks things up in groups, with obvious dimensional differences between the groups.
This all relates to OP and how can you tell if your axles have aged out. When measuring compression against a known weight on that corner and the full load "h" dimension, one can easily determine health of the rods. If, as you say, they are tuned to within 100# of the rating, that calculation would be pretty accurate. If they are "label" rated, the calculation would not be an accurate indicator of axle health.

Yeah, I am not the guy.
Dexter isn't the company either. Dexter does not like retail and the handling of all things retail. It is not what they do. They manufacture stuff including rubber torsion axles. Because they don't handle the retail function (working with customers) they have a distributor network.
Have questions, ask a retailer.
Have Dexter product questions? Ask a Dexter distributor. That is why they exist.

Where did you get that chart from ? I checked my manual & on line manual and can find that chart.
Thanks

On the dexter site, there is a technical manual. I forget what they title it. In there, you can find line drawings of the trailing arm with dimensional indicators. "H" is the total swing of the spindle from its up stop to its down stop. Just measuring your trailer drop isn't telling you a lot. You have to measure the "h" dimension with trailer jacked up. A worn axle rubber will have a small measure "h" dimension.

I think that number is flexible. My 2001 Bambi 19 had settled and was stiff at 18 years old. It had been stored on the ground. I replaced the axle with an upgrade of a few hundred lbs. to recover the ride height, and I now store it indoors and raise the weight off the axle for storage. I do it like this: Unhitch the TT, drop the tongue jack all the way down. Place jack stands under the rear jack points, then raise the tongue jack until TT is level. This raises it to about 2 or 3 inches above normal ride height, with the tires still on the floor but not flat spotted. Quick and easy, I expect to see the new axle last a long time.
