smoother ride from my 71 k10

[Classycustom71,95]

Hi guys, I have been doing alot of research about what to change to avoid knocking my teeth out on every bump in the road.

Any clarification on these would be greatly appreciated:

I understand that a 4 link with bags would be the best but im not about to drop that much money into ordering a kit, I would be confident fabing one but resources and info about the how-to is hard to find.

or I understand that longer leaf springs will lift and smooth out the ride? I am very unsure how i could go about that route with success.

any other success stories?
