Okay so i got ahold of some really good 63in chevy springs for 20 bucks, jus have some surfice rust. But my problem...
I wrecked my truck offroading over the summer and wound up with a bobbed flatbed. We shortened my frame about 4-6 inches!. So is there a way to mount these springs without moving the rear mount? Maybe boomerang shackles or something? Thanks for any help.

But that really doesnt help me with my situation! That basically states i cant move it forward without other problems and the double shackles janky, then it jus says dont bob it. I jus wanna kno if some boomerang shackles would provide enough distance backwards to work with the stock mounts.

 

Long ass springs. You are going to have to add something to mount them to where you cut the frame. Moving them forward 4-6" won't work.

I wasnt planning on moving them forward lol, i jus wanna kno if theres a way to use the stock shackle mounts with a special kind of shackle or setup. i want the axle to stay in the stock position.

 

No. You are going to have to move the front leaf hanger and the shackle mount to keep a relatively close to stock wheelbase. Read the Pirate FAQ thread for 63" chebbies.

Run some ford springs and you wont have to move your rear shackle mount

 

i believe you can run like a 9 or 10 in shackle in the rear and not move the rear mount, i plan on picking some 63's up this weekend im gonna do a double shackle with out moving the rear and see how it works out

 

Please dont DD a double-shackle vehicle.. Any situation under hard braking will cause the weight to be lifted off your springs and the rear to raise up significantly higher than if it were single shackle

 

Yep, that has been done. We have made a couple of sets of 9+" long shackles for that type of application. That will tip your pinion probably 5*-6* but that may be partly offset by the front hanger being lower on the frame:

I agree on the really long shackles. I also agree with the double shackles for offroad only, Those set ups are pretty sweet but can be sketchy on the road.

 

couldnt he also get away with a much larger shackle with a shackle over frame setup? alot of desert trucks do that for the good amount of articulation it provides, and a longer shackle = more leaf spring movement across the range

 

sketchy off road too.. After watching how they unload when side hilling..no thank you.

 

i was waiting for someone to hate on the double shackles ....

 

It's not hate, they're awesome on a trail rig.. AND THATS IT.
When your suspension unloads and you almost crap your pants because your truck feels like it's gonna endo, then you'll agree.

 

I have a double shackle on the rear of my 4Runner, but I have the upper shackle set up so I can bolt it to the frame. To date, I've never unbolted it. For me, it was easier to make the double shackle to move the hanger back for my 56" springs than to try and cut off the old hanger and the re-install it rearward 4" and brace that all up:



And I also used that upper shackle to adjust the hanger width from the stock Toyota hanger width to a wider setup to fit the Orbit Eye spring eye width. Before I used to run a 7" long spring shackle from the stock hanger.

 

Sorry to hijack this thread, but if the object *is* to increase wheelbase, can I leave the front hangers where they are, and move the rears back?

 

yes, but I dont think you have have that much frame space behind the stock shackle hanger. You would have to move the rear 15 inches back with the chevy springs.

 

Well, in theory, yes. But since you move the front hangers ~11" forward of stock, leaving them stock would move your axle back ~11", so if that is what you want, go for it. But since you also normally move the shackle hanger back ~4" (assuming front moved forward 11") you would end up moving the rear shackle hanger back ~15" and that would probably mean extending the frame back about a foot. So what you gain in wheelbase, you would lose by extending the frame back, giving no increase in departure angle if that is a consideration.
