    I want to use the stock 56 inch spring that came off my crewcab and put them on my blazer. I would be using a DIY shackle flip and the correct shackle. My blazer will see DD duties. Is there in drawbacks to having 56's on a DD?

    Not exactly sure what your saying but I would maybe remove a few leaves if they came from a 1 ton, Dave

    No affects on breaking. I just had horrible axle wrap. But that was after my antiwrap bar bent. Once I build a new one all will be good.

    I did the same -- had to remove several leaves, as the 56"s had like nine or ten leaves. I think I ended up with five or six.

    Mine are flexy as all get-out, which does somewhat preclude high-speed manuevers. While good for crawling, too much flex can be bad for DD'ing.

    I would tune it by changing the number of leaves.

    Oh, sorry, wasn't clear. Yes, *my* 56"s were out of my crewcab (a C/20, oddly, but they're the same springs as on a 1-ton single cab), so for Stoney, prolly the same drill ... but as a general case, no, 56"s don't always have so many leaves.

    You should see the ones on my sixpack now ... ten leaves or so, with the upper overloads and the brackets on the frame ... I'm fortunate the truck is so dang tailheavy, being a crewcab, but she still rides like a buckboard.

    I installed the 56's a week ago and have driven it every day since WITHOUT shocks, it does have a small increase in body roll but nothing unbearable. The shackles I used are about .5" longer, I feel certain that another inch on the shackle would help some more. It improved flex/droop ten fold. here are before and after pics.
