    57\" F*rd Rear Spring Q.

    Can I use these with a shackle flip and a stock or slightly modified shackle on a K30 frame with the shackle flip mounted in it's normal location? I'm getting a K30 shortly, and am wondering if this is as easy as it sounds, or even worth the trouble. It appears others have had good luck with the 57's, are the 56" Chevy leaf packs just as good? Thanks!

    Do a search, this has been covered in depth more than once.

    Basically, the 57" F150s are much more flexy but will not be as good for load handling ability. The pin on the 57s is 1" further forward and will need correcting to keep your axle where it belongs. A flip with a new hanger (like the ORD) will work ok, other's have done it. Using the "cut-n-drop" you would need a custom "L" shackle.

    For more info, search...

    Re: 57\" F*rd Rear Spring Q.

    I've seen the swap and understand the benefits and the 57 inch spring versus the K5 52 inch spring, what I am wondering are 2 things-
    1) Can I do the flip on the K30 and use all the stock or mildly modified components to fit the 57 inch spring
    AND
    2) Is it worth it? Will the 57 incher be much better than an aftermarket 56 inch K30 spring.

    rocko-Can you tell I'm looking forward to this? /forums/images/icons/grin.gif

    Re: 57\" F*rd Rear Spring Q.

    With the pooer mans flip, yes you can. I imagine you might be able to get away with the stock shackle as well since your only using a spring that is 1" longer. If your using the ORD flip, you could run them on opposite sides and still use the stock shackle but on the one inch forward installation, you'd need a slightly longer shackle. The 57's are much softer than the 56's and I wouldn't tow with them!

    Re: 57\" F*rd Rear Spring Q.

    That's what I was after. I won't be towing with this rig, so the softer spring in conjunction with the shackle flip won't be an issue to me in that department. I intend to use the f*rd spring, ORD shackle flip, then locate the axle using rockjunkies' 14 bolt spring perches. Thanks for the help!

    Hmm, is it just me or did I basically say the same thing? Hmmm. /forums/images/icons/wink.gif

    Re: 57\" F*rd Rear Spring Q.

    I dont think that you can use ORD's stuff on the k30. (I havent checked the site to see if they offer one for the K30)
    as the spring mounts are different then the other trucks.
    surprizes me that Baddog didnt mention that as I thought he was a K30 owner
    you can knock the rivets out of the hangers and use 1/2 3/4 ton hangers if you want to change the rearend spring pads distance, you will gain lift from that as the frame depth differs where the front hanger is attached
    it would be much easier to follow tRusty's method (I am sorry I dont know the originator of the idea/method no offence intended),
    cut the bottom out of the hanger,
    move it back on the frame,
    bolt it in,
    add reinforcements,
    redrill the spring pack to centre the tire in the wheelwell

    If I missed or got something wrong I am certain some paying members will chime in to fix it up

    Well as I am a paying member... /forums/images/icons/wink.gif

    I didn't mention that because, IIRC, ORD makes brackets for 1 ton spacing. But, you have to remember to tell him that's what you need (or at least that it's going on a K30). Maybe BerregoK5 can confirm since my word holds no weight for him. /forums/images/icons/laugh.gif

    Re: 57\" F*rd Rear Spring Q.

    see now you made me go google search for ORDs site and look it up.... /forums/images/icons/tongue.gif

    paying members ain't all that Bad after all!

    </font><blockquote><font class="small">In reply to:</font><hr />
    1-ton trucks require a different flip kit than k5's, k10's and k20's. The kit is the same price, we just need to know it's for a 1-ton when you order it. The difference is that the spring center spacing on the 1-ton axle is only 40 1/2", and on the rest of the trucks, it's 42 1/2". The brackets are a different shape to reflect that.

    Hey, I got an idea, "ORD makes brackets for 1 ton spacing."...

    You'd think Baddog would have known that! /forums/images/icons/grin.gif
