What did you have to do? I have a 78 k-5...
I run a shackle flip w/ an extended shackle and 57's... not 56's, but close enough!
I'm thinking about not doing a shackle flip though. Thanks for the info...
If you can find a used or replica echobit style flip you just flip the brackets around backwards and change left to right . We did this on the 75 when it was Dave's , lined right up to the 56 inch springs . Just rockin the truck back and forth on the ground you could already tell it was going to be some sexy flex
i did....shackle flip..with homemeade 6.5" long shackles...moved my rear hangers back 2" and the angle is good...
Matt (az-k5) and I did this to his truck about 2 weeks ago. He had a shackle flip on the truck already (homebrew) and he just built some new longer shackles. We installed the new longer shackles and 56's and if flex's like a mother. It rides really soft to because his shackle angle is very good.
P.S. I believe Jay had the echobit style on his burb with 56's and broke a shackle. I would build your own HD shackles or have someone build you a set.
Like this but longer
I am running the echo bit shackle flip backwards, and we were able to put in 56's
flexy as hell!
It is a killer mod. It will ride like butter and flex like crazy. You will have to have something better than the factory shock design to accomadate all of the travel. I also had to play with my e-brake cable so it wouldn't snap.
Here is the shackle angle
I just put some pics in my sig link of the shackle bracket and the design of the shackle. This shackle is more than over kill. I ran one with less weld surface and only 1.5 x .25 flat stock for the sides for that last 3 years with no problems and they are still being used in harley's rig. The new ones are 2 x .25" flat stock. The only reason I see to step up to 3/8" plate is for bolt hole strenght (thicker steel has less tendancy to waller out) this can easily be overcome buy just welding the correct size thick washer around the bolt hole.
Its a great mod, I did a shackle flip as well using front hangers just moving them back.
Just do yourself a favor and build some heavy shackles.
This is what a stock shackle does with some mild wheeling:
OK, time for the usual question in a post like this one...
What do the 56" springs come out of?
yep and im now doing to the 74 also, but this time im using 56's out of a 3/4 ton truck(because they are free) and pulling the overload leaf out of the pack. the only problem for me is that echobit is not around anymore. so im unshure if i should make a hanger or make a replica echobit
i know that was nice of me to do that for u...
The softest ones (5 spring plus overload) are in light duty 2wd 1/2 ton suburbans (those are what I have). A 3/4 ton truck, or any suburban will have them. I am running the original 5 leaves with no overload.
How much more lift, if any, does the 56/57" with echobit flip compair to the 52" with echobit flip?
It is the same amount of lift with 56's as with 52's.
73-91 are the ones I would look for. I think the newer gen II body style still uses 56" but am not positive.
Move your brackets back 4" and you are golden.
Separate names with a comma.
