Reverse Shackle Pics wanted

[gonecrazyi]

I am getting ready to start putting together my crew cab project and have decided to use my 2wd cc frame instead of the 4x4 frame to build my 4x4.

I want to do a reverse shackle on the front using rear springs instead of the worn out 4in lift springs I have now. I have seen others do it and the ride is said to be better and they will also provide a lift at the same time.

My plan is to use the stock rear brackets in there stock 4x4 location in the back with the swinging part of the rearend shackles for movement. In the front I plan to box the frame and weld a piece of square tubing to mount the front spring brackets to.

Being that the rear springs are longer than the front I know Im going to have to move the front mounts out a little over an inch from stock. I also need to get center pin measurements to ensure that the axle is far enough forward. I suppose I would rather have it farther forward than backward but have not looked it over enough to be sure.


I would like to get everybody's opinions as well as other reverse shackle conversion pics.


This truck will be built for hauling gooseneck and dump trailers. If you ask a couple of the guys that have met me, I use my truck to the fullest so it needs to be done properly with plenty of strength.


Once I get this step done it will be time to gut and insulate the cab, paint the frame and drop in on the low millage 6.9s or 7.3s Ive collected. I plan to trade a dana 60 and a crew cab frame for a 6.9 with documented 65k with a new banks turbo kit and a 7.3 with 110k from an ambulance. This trade will also come with a bunch of body parts ect. Now all need is a gearvendors or ranger overdrive box lol.


Thanks for any input and please post any pics that you may have.

I didn't box the front frame horns in on mine, just bolted to the sides and to the bottom of the frame. I acutally used a set of rear leaf spring shackles from my old 03 F150 modified to work because the stock shackles are not as wide as the rear stock hanger.

text me tommorow and i'll attach some pictures

Alright ill do that thanks.

I like the idea of the square tube because then you can integrate a reese hitch into it. If you do that, you do realize it'll give you more lift right? Why not just swap in a front set of F-Superduty springs......I KNOW you've got some. If anyone is wondering where all the used IDI parts are, they're at Billy's house!

I don't have a set of superduty springs yet. My 4in lift springs are so worn that the shackles are bottomed out and hitting the frame. Im looking to get around 6 inches or so of lift with a ride that doesn't leave my kidneys hurting going down the dirt road to my parts collection.

I also plan to add a reese hitch to the front in the process. But don't really want it to be connected to my shackles. They already take enough abuse.

You are talking about super duty springs. So I understand better you are talking bout 99 and newer springs? Now are you using the front or the rear springs off a super duty and putting in the front off an obs 250 with ttb what mods does it take to make the work and how much lift is gained? I have a new set of 99 f350 snow plow front springs I would like to put in the front of my sons 92 f250 4x4. Thanks for any and all info.
Thanks Keith

front superduty (99+) springs are approx 3" long, so the shackle reveral is needed but they ride better and flex better. the rears are a semi-direct swap, i believe the hole in the OBS shackle needs to be enlaged for the bigger bolt used on the SD spring bushing eyelet.

Putting them in an F-250 wil still require reversing the shackles, but i dont knw how it will work with the TTB.

I want to use rear springs from an 80-97 f250/350 on the front. According to the tape measure it will take 1-2 inces more than a stock spring.

As for the term superduty, we were refering to an 80s -97 f450.

1st A RSK will not work w TTB. You have to have a D60 to use a RSK.

2nd, why would you want to use a rear spring (3,200lb) in place of a 2,200lb spring?

actually you can use the RSK with ttb on a F250. Just need pivot drop brackets.

one issue with this is the center pin is, well centered in the rear springs. the front spring it is not. the pin is closer to the front of the pack. i been measuring springs alot trying to decide what i wana run. i am trying to move the front alxe forward some in the process.

there is all the different spring measurements u need.


the rear springs u want to use are alot longer than u think.

I measured the center pins last night against my 4 on lift springs and the stock springs an they we're relativly close. Ill try to find them tonight. If im making my own front mounts it should be easy to make up for the pin difference. I was also wanted to move the axle a little further forword.

No you cant. The lift is not the issue. It is how the axle is allowed to move w the RSK. It will bind and break things. Ask me how I know. been there broke that.
