    ORD 4\" shackle flip

    Can anyone who has 4" rear superlift springs and a 4" ORD shackle flip tell me how much the flip moved the axle forward. I am getting ready to do the 4" shackle flip and want to make sure that I don't need to get some zero rates to relocate the axle back some due to the arch of the spring moving the axle forward too far.

    If you want to move it back without z-rates you can just drill a new hole in the spring perch 1" farther forward to move the axle back. This will work on all steel perches but I think the stock 14FF cast iron ones have a void there. You will also have to notch out the u-bolt plate because it will move back as well.

    I was already thinking about making new perches anyway and making them with a couple different holes to move the axle since I will need to correct pinion angle again anyway. So you are saying the axle will move forward by 1 inch?

    PM Rockjunkie- he was making some solid spring perches a while back... thats where i picked up mine. Very Beefy. /forums/images/graemlins/thumb.gif
    IF he isn't making them any more PM Tony P. I think he is doing 14ff perches also.

    I don't know how far it will move back but I couldn't see it being more than 1". I made my own perches out of some 2.5 x.25 wall square tubing and drilled the hole offset 1". The axle sets a bit to the front from the factory...so it is hard to tell how far the axle actally moved with the shackle flip.

    How did you cut the tubing into the curve to form the perch?

    IIRC, Triaged clamped the two pieces of tubing together and used a hole saw to make the half round notches.

    When I made mine, I drew the perches up and printed them out full scale using my CAD software. I then traced and scribed the shape of the notch to the tubing. I roughed the notched out with a gas-ax and then fine tuned the opening with a grinder. /forums/images/graemlins/thumb.gif

    You can even do it with a sabersaw and a metal-cutting blade. Cut the hole slightly undersize, and then use a grinding wheel, to create a nice clean final shape. /forums/images/graemlins/thumb.gif

    Re: ORD 4\" shackle flip

    Beast is right. I used a 3.5" hole saw to do it. Scarry thing is that my drill press is made for wood and spins way to fast for the hole saw so I did it by hand /forums/images/graemlins/eek.gif I found out that my 1/2 Milwaukee puts out plenty of torque. I had it braced against my leg when I was doing it and it threw me on the ground once when it got hung up. That hurt....so I can't sugest anyone else doing it that way unless you have a drill press that turns nice and slow. It did however go quick and left a nice finish.
