Suspension Upgrades on 72 C20
 

Hi all, I am looking to upgrade the old suspension on my 3/4 ton C20. I have stock original Leaves and Old shocks. I'm looking to upgrade to stand hauling heave loads such as Metal and wood. And would also like to pull a goose neck and a regular car hauling trailer. I wanted to know what idea's and recommendations some you have on part etc. Also would love to see some photo's of some upgraded suspension if you have any.

P.S. Along with the leaves I have a Dana 60 axle and the truck is 2 wheel drive. Really just looking to Beef the rear for now.

How many leafs do you have now? I added three extra leafs into the stack on my 71 C 20 and it stiffened it right up. Haven't had a huge load on yet since then but had 2300 pounds of roof shingle tear offs and it barely felt it. I bought new u bolts and center bolts from the local spring shop and put some leafs I had from some parts vehicles in. All the leafs original and the added ones were in good shape though. Right now I have 8 leafs plus the heavy overload leaf on the bottom. The spring shop says you can estimate adding 500 lbs of capacity for every leaf added to the stack. So I figure 3 leafs per side added 1500. Of course springs are just part of it ,you have to remember the brakes and the frame remain the same, it just keeps it from squatting quite so much.
