    this is my first post,and i would like to say that this is one awsome site.

    my question is, I just got a free junk front axel, for a 80's chevy,but it came with a drop steering arm, and leaf springs, that have a positive arch to them. the guy said it was a 4inch lift, and he gave me some 4inch blocks. I got them home, got the springs off. I put a strait edge across the two leaf spring bolt holes, and measured them, from the holes to the bottom of the 6 leafs, it was 6 and a half inches

    i'm going to put these on my 85 k20, i just want to know how much lift it will give me.

    By the time you install those and put the weight of the truck on them it should flatten out quite a bit.

    You'd be surprised. There is gonna be close to 2000 lbs on those springs.

    BTW you spelled Illinois wrong...:p:

    my 4" rancho lift springs have 5 leaves. i never measured the height on these, but the 6" i did have had 8" from the bolt holes to the bottom of the leaves. so it sounds like yours are 4"

    the guy also had a set of 5 inch blocks, so if its a little more than a four inch lift, i can go get those.

    or what about a shackle flip and one inch blocks
