1995 k3500 vs 2000 k2500 Rear Springs, Both 6 Leaf, Same Rating?

[Edward Case]

I am looking at both springs and they are a 6 pack, would the k3500 spring be made differently to offer more carrying capacity or are these the same spring?

It doesn't look like it here. I think you're looking at 2500HD compared to regular 3500 springs.
