Shackle Inversion
Just got back from the junkyard. Got a pretty good deal on some rear leafs. My have two cracked leaves and were pretty rusty. I got the leaves, u-bolts, plates, blocks, shackle, front mount and rear mount. For both sides. I am seriously looking into lifting my truck. I have everything I need to do the Shackle Inversion but does anyone have any specs on it. I would just like to get it right the first time and not have to mess with anything. Thanks for the help.

Except for getting the rivets out, the shackle flip is easy. The rear spring hanger needs to bolt on 180* from it's stock orientation. Also the holes in the frame and bracket need to be drilled out to accept 1/2" grade 8 bolts. If you need a pic of what the insalled brackets look like, let me know and I'll e-mail you a one.

Well I am in the mist of working on it right now. But it seems as though it is going to lift it too much.
Here is the question:
Can i run the rear suspension with out the block?? Seems like I could since it doesn't have any offset and it isn't anythng soft or the like. Whatcha think?

I drew it all out in AutoCAD, seems that it would lift it too high if it were flipped 180° - i think if you turned it 180 and just used the two lower holes in the frame and used a piece of angle under the frame to catch the other two holes it would work. I can send over a pic if you send me your email address- gdavis@rahco.com

I would appreciate those pics. Can you flip on front too? This will be on a 75 F150.

no, actually I drew up some longer shackles for the front
made a .dxf drawing out of them and used a computer burn table to make the parts out of 3/8" plate - If somebody can tell me quickly how to post a pic on this board I do it.

O.K. - If you check my gallery to the left, I have put up pics for the lift kit in there.
Thanks

Shackle Inversion
I just finished my flip today. Using the method I described, I picked up 2". This was reusing all existing holes and rotating the bracket 180*. This was actually 2" less than I was expecting. I did the shackle flip so I could get rid of the 4" blocks I got with my 6" lift kit. The truck now sits 2" lower in the rear than it did with the blocks. Needless to say, I'm a bit dissapointed as I was expecting 4-5". Basically I was expecting it to come out roughly the same ride height that it had before I removed the blocks and did the flip.
Here's what mine looks like now.
If I were to relocate the brackets the way gdavis2265 drew up (nice drawings by the way) then I believe i'd be right around 4-5".
Obviously, there are a few variables here such as the condition of the springs and such. Mine are probably shot.
I want to get rid of the factory blocks too so I think I'm making a trip the spring shop tomorrow to get some new leafs made since my flip didn't come out right. I was hoping to get off cheap for now.

Thanks Scott, too bad you could'nt just buy a longer link that goes between the hanger and spring.

I just dropped off an old spring this morning for the shop to work from.

Well i did it. Looks like I am going to have to order some huge lift springs for the front. I am sure that i have gotten atleast 4 inches of lift with what i did. I used the front hanger braket from a similar year ford truck and mounted in the rear and that was used to the inversion. I don't knwo how much lift i have because i didn't take any measurement. I have a huge rake right now. can anybody tell me the distance between there axle and the frame, so that i can have some idea of how much lift i have. Mine measures 15.5 inches right now. also i left out the rear stock blocks. My truck would be on it's nose if i did. thanks.

Just subtract your pre-install measurements from the post-install measurements...............
Comapring to someone elses truck will be inaccurate--age, loads, sag, etc. different. I am picking up a '75 4x4 f150 (sight unseen) this weekend and can measure then (assuming it is still stock)
