1969 gmc heavy half ton, leaf spring removal for drop and ease up stiffness

[Mike C]

The overload is for when you are loading the truck up to rated capacity even. Once you get a certain amount of weight in the truck, the spring place flattens out to transfer weight to that leaf.

The parts axle I had from a 71-72 truck that I put in my 69 came with the standard leaf pack which was 3 leaves plus the overload.
