    56\" rear springs, what to do to them

    I have a set of 56" rear springs with the teflon on the spring ends. They have 7 leaves in them plus the overload. I am planning to take 3 out and flip the overload. What else should I do to them before putting them in?

    Head down to your local farm supply store and get some black graphite paint and cover your freshly cleaned (wire wheel) springs.

    They use this stuff to protect farm equipment that sits outside for years at a time. Nice and flexible. Works great for Springs!

    Wayne,

    I don't have that much experience with the 56" Chevy's, but I've experimented alot with the 57" F-150 springs.

    I've learned to have a MINIMUM of 5 leaves in the pack. This is the setup I've used for a "flexible" spring pack for a 4" lift. So, I'd suggest the same for your springs... at least 5 leaves.
    Also make sure that your finished pack uses some kind of clamp to keep the leaves aligned.

    Is that 5 including the overload? I doubt it is but just checking. I know I need to keep them clamped to keep them inline. I plan to use these springs with your springer kit someday but right now the springer is out of the buget. /forums/images/icons/frown.gif

    Sorry... didn't make that clear..

    That's 5 not including the O/L.

    BTW, if you have acces to some F-150 O/L leaves, they have a little more arch than the Chevy's - so flipping them works a little better cuz they allow more compression (negative arch).

    Total newbee question:
    What do those 56"s come out of? What are you planing on doing running them with the pin where it is moving your wheelbase out or just running a longer shackle (which would still lengthen the wheel base depending on where the pin is drilled)? I am looking for a way to get my 74 to flex this seems logical.

    I would have to junkyard shop for some Ford springs and these were free. I guess I will try them for now and do the Springer with some 57's if I don't like this set up.

    Re: 56\" rear springs, what to do to them

    You can find 56" springs in 3/4 and 1 ton trucks. I am planning to leave the pin in the stock location since it is the same distance back from the front of the spring as a stock K5 spring. The difference is they are 4" longer in the rear half of the spring. If you want your 74 to really flex then contact Marv for his springer set up.

    Re: 56\" rear springs, what to do to them

    I have the same springs in my K/5. I removed two leafs....very soft and flexy set-up.I recently added one of the leafs, it seems to ride pretty good.And I did keep the O/L just flipped it.I've been thinking of flipping the springs where the 30" long side is towards the front to extend the whelbase and increase the departure angle.Oh yeah i did the shackle flip mod(one of the best ideas out there!!!).Mike

    Re: 56\" rear springs, what to do to them

    heres one----i have the ORD shackle flip with the stock springs, but with lowrider extended shackles. the shackles are almost straight up and down, so--- if i added the 56"ers, would it push my shackle rearward so the angle would
    be is a more desirable 45* +/-????

    also, are the early 80's bronco rear springs the same as the F-150 ones?? a buddy just got one and said i could have them.

    thanks rob

    Check to see if the Bronco springs are 3" wide. If so, no worky..!

    Even some F-150's had 3" wide springs. Need to make sure you get the 2.5" wide ones.

    How did those shackles work out, strong? I'm looking at getting a longer shackle (or making one). how much longer are they, were did you get them?

    Re: 56\" rear springs, what to do to them

    I have heard they are alot weeker then stock shackles. Other guys with bent stock shackles have comented how "beefy" mine look (stock)....
    I think you should just make your own.
