    can you still haul weight after a basic rear spring shackle flip ?

    you dont really have to remove the spring hanger bracket from the frame rail to do this right ? what are the gains that you get by doing this ? hyow much does it raise back of the truck ? back ride any differently than before flip ?

    and what size and grade are stock shackle bolts ? man they must be strong they have to hold a ton of weight esepcially whehn truck is loaded down, if one of them bolts ever broke them damn..... could be a bad thing to happen /forums/images/graemlins/frown.gif


    thanks

    By the concern over removing the bracket I assume you are doing a home made style. Yes it is possible to make it work without removeing the bracket (I did mine this way). A lot of gusseting is needed for a well built load bearing design. The oringinal shackle is not up for the task. It will collapse (3 of mine did). Build one out of at least 1/4" make it look like a capital "A" and that should work.
    The stock bolts are 9/16, there is a debate as to use grade 5 or grade 8. G5 will bend before it will shear and hopfully not fall apart. G8 will shear very quickly when overloaded (ask me how I know).
    I will try to get some pics of my C.E.E. flip for you and the shackles I made to match.

    All stock rear spring bolts are 9/16-18 about 5" long or so. Shackle flips make your rear suspension really soft and flexy and lift varies with which one you choose.

    On the grade issue:

    Stock bolts are grade 8 I believe.

    Grade 5 bolts will not only bend, but they will break before a Grade 8 bolt will BEND.

    Body bolts I know for a fact are 5s, but I think the ones I cut out of my rear springs were 8s. I am not sure what I replaced them with, one or the other, probably 5s, which are plenty anyway.

    yeah homemade stock flip


    i wouldnt think that grade 5 would be able to streth when are used for shackles since use a nut, would keep the bolts pulled tight straight

    humm..

    and does this flip add much height to rear of truck ?

    do you think stock hangers would still be weak after welding a piece across tops of them after the flip ?

    thanks

    3 lines = Grade 5
    6 lines = Grade 8

    most other marks are manufacturer, not important

    I have a half ton short box pickup and tow a 6000 pound travel trailer with a shackle flip for about 2 years and have had no problems. /forums/images/graemlins/truck.gif

    The question is, whether he's trying to haul 6000 lbs of concrete in the back of his truck, or on a trailer.

    I've personalyl only loaded the back of my truck up with about 2000 lbs worth of bricks/concrete. Flip held up without any problems. I was afraid of bumps sending bricks flying though! /forums/images/graemlins/smile.gif

    Youll get 4" from a homemade shackle flip. When i did mine I replaced all bolts with grade 8.

    I wouldnt think that would be a problem normally- however, when you do your own flip, it really is cutting down on some of the original structural design of the hanger. By how much, I dont know, but I do know that either the ORD, or the Echobit will retain / increase the stock capability.

    The home made versions vary, by how much you end up cutting yourself.
