front axle shackle angle question

with my mock up this afternoon, the front axle shackles appear to be straight up and down, should I move the rear mount to hange this angle before I weld the brackets on?

Id like to think its from my super precise measurments and planning, that I arrived at this, since I spaced them according to the rear spring length, but more than likely its luck of the draw.

in a Spring over configuration what should the angle of the front shackle be? Im not Shackle reversed either, the shackle is in the front of the truck.

any ideas opinons?

Re: front axle shackle angle question

I would try to get a slight angle on the shackles. They should work straight up and down, but I think they will be a little smoother with a slight angle /

Re: front axle shackle angle question

From what I've heard, straight up & down will give a rough ride. They need to be angled.

Re: front axle shackle angle question

I KNOW they need to be angled, which direction towards the spring or away from teh spring?

Ive heard BOBCA before say that 11 degress was the magic number.

I assume 11 degrees towards the spring.

how about this, anyone got some pictures handy of there shackles? stock or other wise?

thanks

Re: front axle shackle angle question

hey ozark.. do you have wieght on it? with no wieght they will be straight up and down.. but you want a slight angle on them.. in the front.. the bottom portion (spring) will be forward of the top (hanger) portion.. 11 degrees does sound about right.. / about like that [img]/wwwthreads_images/icons/smile.gif[/img]

That was 20 deg from vertical.

Re: front axle shackle angle question

Are they new springs ? you'll want to allow for them straighting out if they are new, otherwise I'd set them slightly angled spring eye closer to the front.

Re: front axle shackle angle question

oh Sorry for misquoting you bobca, my memory isnt what it should be.

the springs are used, all cj rears, im using them front and rear. No wheight on them, its a bare frame not even axles bolted up yet.



I can jysy redrill the holes in my brackets to move the rear hanger back about an inch ( thats all the room I have) I held the spring in place and the angle looks about right.

the top of the shackle is towards the front of the Jeep, the spring eye at the bottom of the shackle is a little farther back from the top of te shackle.

wait, thats baCKwarsds from what Jeepgod said.

one way will hinder compression, one will hinder droop right?

when I put weight on it they will push forwards just like JeepGod says ( I jumped up and down on it, and I could see the direction of travel)

so maybe I shold leave it?

all this work to meagerly re engineer what they had already figured ou with way more resources tan I have, whay do I bother?

thanks for the ideas, please keep them coming I dont fully understand just yet.

Re: front axle shackle angle question

if youre talkin bare frame.. even just on axles.. then it should be ATLEAST vertical.. once you add the wieght they will bow out to the front like they should..
