More leaf spring madness.

I would worry about increased spring wrap removing lower leafs. What I might do if I was in your situation is disassemble the C10 packs. Look for differences on the individual leafs from each pack side to side. Replace leafs with discrepancies on both packs with corresponding leafs from the donor springs.

I did that a little bit by removing the tire, and pulling out my dial calipers.

The leaf spring pack I want to swap in weighs 20 pounds more atleast then the original one. A few pounds is due to these metal shims in the pack.

There is a difference in every leafs thickness.

Lengths are the same.

Different style slide straps. My C10 used straps where the K20 used pads+shims.

Then to round this off. The bushing diameter is 1.75" vs the Factory 1.5" every website says it should be.

So I am beginning to believe the leafs maybe some form of aftermarket. Which explains the bushing, but they are not heavy duty or 12 leaf for smooth ride. Which alot of aftermarket springs would be to help with sales. Much less lift springs.

So what they are I am at a loss.

I swapped one on to replace my sagged leaf for a quick visual. It raised my truck 1.5" above the other spring, and was horrifically stiff.

Yes I am aware that's what she said.
