Having read all the posts here on Torsion Arms, I immediately had to go out and check mine.(They're horizontal!) However, I also noticed that the bracket that attaches the Torsion Arm axle to the trailer frame has TWO adjustments slots for bolting. Mine is in the Bottom slot, therefore, it looks as though I could jack up the trailer and move the axle to the Upper slot and gain some height and the Torsion arm would then again be slightly below horizontal. Should gain back some action from the system.
Anyone know if this is "right" thinking? Sure, I can see someday replacing the axles, drums, tires, etc. , but for now this looks like an option. Perhaps the factory knew the system would settle after some years and allowed for it?
Looks like it wouldn't be "that" hard to make an adjustment.
