    shackle flip with 56\"s, 57\"\' conversion and gas tank questions

    okay, this fall, hopefully within a few weeks i'll be installing a 4" shackle flip on my '89 suburban. i have 56" springs, so obviously i just mount it where the existing shackle mount is right? and if i were to go to 57"s one day all i'd have to do is get longer shackles right? or would it be better to flip them around? how hard is it to remove the gas tank? and do i really have to? /forums/images/icons/confused.gif

    I'll take some pics when I do this install for you to check out. I have a K30 with the 56" rears, and I am planning to do what you have talked about. Hopefully will be done within the month. I'll let you know what I find and get the pics up for you to inspect.

    It appears that way. According to those I have spoken with, the flip (for something with 56" stock), the ford springs, and the stock shackle creates a good rear shackle angle, and it improves with the use of the longer rear shackle. I will try it both ways and let you know how both work out.

    so if a guy had the 52s on his blazer..then wouldnt he get better flex with the 56s?? with enough leafs removed to make them close to the same rates as the shorter ones??just a thought......

    Most guy's don't remove the tank. You can swing it down to get to the rivet's. If I were doin the flip I would remove the tank. Get more room to work,also there would be no fire hazard. /forums/images/icons/tongue.gif

    in switching from 56 chev springs to 57 ford springs, would the center bolt holes be near the right position? /forums/images/icons/blush.gif

    Re: shackle flip with 56\"s, 57\"\' conversion and gas tank questions

    Shackle angle will probably be Ok with 57's, haven't really checked it out but educated guess says you'll be in pretty good shape.

    As for the tank, I was able to just hinge the tank down on my Sub from the front and snake my arm in there to access the inside. Not too big a deal, just took 2 guys. Really we weren't a long ways away from just removing the tank.

    Best tool for the rivets is a good air chisel running on plenty of air pressure. We finally bought a snap on air chisel and at 150 psi inlet pressure it devours rivet heads. Literally 10 seconds of pounding on it and you're done. Pretty cool. I highly suggest renting/borrowing a good air chisel for this job.....
