How many leaves should I run in 56" springs? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

This set of 56" I was planning on using for rear of my Blazer has 9 leaves - 8 regular & 1 overload I think. They're out from under a single wheel 1ton CUCV. So I'm sure they're pretty stiff as is. I'm gonna take them apart & clean/paint them anyway, so which leaves & how many should I take out for a better ride?

Okay I'll try saying it another way...
Let me see some pics of other folk's 56" springs; how many leaves are in them?

Here's what I have. It looks like there are 8 in mine. These are out of a 3/4 ton.

How rough is the ride? I don't mind & do like it a little stiff but not too rough.

Compared to what? The only thing I have to compare it to was the 40 year old stock warn out suspension that was pretty rough as it was. Any lifted vehicle is going to be a little stiff but I don't think this setup is bad at all. I would think it would have to be a better ride than using 6" lift springs in the rear and personally I would never use blocks so this was my choice.

i went with 56 inch springs off a cucv truck for my 68. the spring center pin isnt the same as the factory spring so i had to run the springs backwards and use an 1.5 zerorate block from diy4x4 to move the axle forward, but its still a half an inch back from factory spec, but i doubt anyone will even notice it. i used the rear hangers and shackles from the same truck. over all it ended up giving me a little more than 4inches of lift in the rear. as for the ride of it, i have no idea yet as im not done building the truck :waah

cucv springs (top) and stock 68 spring (bottom)

after i finished up getting everything measured out and bolted up.

i took the top overload spring and spacer block out and left everything else on, theres 9 leafs left in the pack.

gave it some army green accents to set it off
