Sagging Truck Bed?

I was under the impression payload cannot be increased because there are other safety factors such as frame, axle, brake components etc that aren’t changed when beefing up leafs. Custom spring packs just replace stock springs that could warp over time under constant load towards max, and reduce bouncing. Shackles only to correct drop as suggested are fine if capped and not hauling regularly.

 

I had no idea a single leaf was that cheap. I guess that would mean one added leaf on each side for $200+ on parts alone isn’t so bad. I’ll look into it.
