Trying to rate leaf springs by the number in the spring pack is a hit or miss way of doing things. If you can find the manufacture of the springs and look at spring charts provided by them might work. A little searching on the net will find 26" springs with 4 leafs rated at 3000lbs, the same chart had 3 leaf springs rated at 3000lb also. These were 1.75 width, which is pretty standard. I also saw 3000lb springs with 5 leafs so it's pretty much a******shoot trying to rate springs that way. I ended up just ordering springs that had a rate as close to axle capacity I could find.

So true. Even measuring the leaf thickness and arch on well used springs is a******shoot. Best to know what OEM it started with (build sheet), then source the needed capacity in the proper length and arch needed. One of most inclusive spring lists around is the one on the Stengel Bros Website.
