Hey Hector, thanks for all the info! I got those numbers over to Dexter, and they were able to tell me that this is a 2,800 lb axle with a 83.75" hub face center to center, 66.75" spring seat center to center and is underslung.
If there is something you were looking for in particular to this axle, please feel free to let me know!

So both axles can handle 5,600 lbs? I just have the frame of the Rv I was thinking of putting a 500 gallon smoker on it with a 40” x 4 ft long square fire box
