I had a broken spring on my trailer with 3,500 lbs. axles and replaced all with OEM spec 1,750 springs. They looked too flat and almost a reverse curve to them. Subsequently replaced them with 2,400 lbs springs (PR4 with 4 leaves) and it raised the the frame 2" and the springs have the appropriate looking curve while loaded. The weight on my axles at the scale loaded for RVing with full fresh water tank & empty holding tanks was 5,700 vs 7,800 GVWR.
I believe the original and first replacement springs didn't meet the 1,750 spec because at that weight they should not be flat. Perhaps the 2,400 lbs springs don't meet specs either but they do the job for my 7,800 GVWR trailer. I would suggest you change the springs and then shim IF required.
