I'm setting up leaf springs (front end) on a bare frame and I ran into a problem. Do the springs have to be level at the centering pin? If so I'm going to have super long front hangers. Will I have any suspension issues?

Nice crosspost. :shaking:

NO. You adjust your pinion angel with the perches on the axle.

can't get any answers that make sense

Thanks malibu

do you have matching springs? i dont think your question makes sense.

What vehicle are you working on and what springs are you attempting to install? That will help everybody see what the issues are, that you are running into.

For a tuesday, you people are being kind!

yj bare frame. wagoneer springs. shackle reversal. I'm making all my own shackles, front hangers, and spring pads. Where I want to put the spring, it causes the spring to be unlevel at the center pin. To make it level I will have a extremely long front hanger. Does it matter if it is level as long as my caster and pinion angle are perfect. When I hit a bump in the road the spring looks like it would move backward instead of straight up and down.

people put wagoneer springs on YJ's all the time and i've never seen them with 2 foot shackles on em. Search around and see how other people have mounted theirs.

which waggy springs

how long center pin to bushing. what arch. are they lift springs. how long do your shackles look like they might be what pinion angle do you want. what front end do you want.



WAY TOOOO little information to give you much for a response without just providing you a Wild ASS Guess.... BTW any advise will still be a Wild ass guess

No it doesn't have to be level (ie: parallel to the ground). Yes the axle will travel in an arc that moves towards the rear as the spring compresses. It would do this even if the spring perch were level (unless your springs were perfectly flat at ride height). This is one of the reasons a long travel driveshaft is recommended for shackle reversal.
None of this is rocket science, and there's 8 years of history available to you for the mere price of $20. Search is your friend.

:shaking: Ok retard..... What did you not understand about my reply in your General4x4 section post. NO, the pin does not have to be vertical. Can you understand that? The pin is not in the center of the leaf. It can be positioned fore or aft of the centerline to accomdate wheel base. It can be up the arc of the spring because of that. So, it can affect the castor. I told you to make sure you install the hangers so the castor is ok. I think that is pretty clear huh?
The only way your axle is going to move foward under compression is if you put the shackle hanger so far back on the frame, the shackle would be facing foward, aka a bent spring for sure

Kieth, obviously you don't understand the question (and that's ok). All of your answers I know already and I didn't ask for them. I'll check a different web site.... Nice attitude
Thanks

Keith's answer is correct. My answer is correct. If you're still looking for answers clearly you're not getting it.
Once more:
1) Don't use super long front hangers.
2) Weld new perches on to adjust for caster/pinion angle.
3) Get a long travel drive shaft.
If you bothered reading the general information posts you would know that attitude comes with the territory.

If you study most "factory" style leaf spring setups they are for the most part level from hanger to shackle. You can vary by a couple inches, but if they vary by 6" you will have handling quirks because the suspension will move too much front to back. In a shackle reversal front axle application, with the front of the spring tucked up tight to the frame and the rear shackle under the frame there will be significant angle...it will lead to major brake dive and other suspension oddities. (I know because that is how I built mine at first) I have since lowered my front fixed spring eyes about 2" and replaced the shackles with sliders. I have yet to drive it so I can't say how much it will be improved.

In a nutshell, try to be level from front attachment to rear attachment in the spring, or vary by a few inches max, but not six inches.

Please do...and for around here it was a "sunday morning glad to meet ya" conversation.

I didnt look at the post in General but here is my answer if you ever come back to see. Please excuse the kindergarden art :)

A. You have this. I had this when i had a waggy 44, waggy springs and a reversal. You just spin the pinion up to where you need it and weld on the perches.

B. This is what you say you dont want. Agreed, no one wants that.

C. When i got a 60 the passenger perch is cast in and i also wanted to lower my rig a lot so i did this. Got the idea from a Shaffer build thread. If you dont need to lower it as much you could just put a hole in the bottom of the frame and sleeve it for the shackle.
