much in favor of longer shackles, before welding the perches. Also might need a few spring bushings.

Are you CV rear? pinion looks up a bit for none CV

8" total spring lift, i think your going to have to go with a lift spring to get that much. WELL fronts at least.

44s on cruiser axles, shall i assume more street then not?
 
i dont think im going to need cv in the rear just the front .. in going to put a reversal on it to give me a lil more wheelbase then i think a cv in the front will fix it all....
yes this is a mostly street machine a lil mud and off road, nothin too extreme.
im a flatlander here in ill. theres really no good places to get tooo extreme
 
spring or shackle reversal?

custom cv only then. $$$$ front. rear make sure you check your u joint angles when setting the rear pinion angle up to run the none CV shaft.


if you look there are places, i am not all that rocky, but you travel a bit you can find some.

Dude.....

Anyway, I could care less if you drive a dangerous rig on the trail, but it is the street that worries me the most. That is the reason to fix bootie fab.
 
so if i put a shackle reversal and a spring reversal on the front to give a lil more leingth ,,, do u think a cv axle will work good on it or do i NEED to not do any reversal at all...... cuz the springs reversed will give another 2 inches of leingth to play withth the angle .....also if i need to i can cut and turn the axles ..... if i did all of that do u thin it would b ok ohh ya ....thank ALOT for all the help guys keepm commin

OK, you are binding now with regular shackles. When the front end drops out now the pinion actually reduces the angle you have.

If you do a shackle reversal, the pinion will dive when the front drops.

Your binding will be worse.
 
so how does everybody that had an soa and a shackle reversal get around the the binding?? i understand now that the binding will be worse, but there has to be a way around it ...there always is ,,
from what ive heard is that its almost pointless to put a shackle reversal on, with out putting on aftermarket springs, well if they put on aftermaket springs then there in the same perdickament that im in.......how do they get around it??? reason for me wanting the shackle reversal is because i will get new springs for it in the future... mine r week.

OK, I have a spring over and a shackle reversal. My front springs are flat. That nets about 5" of total lift. No fenders and I run 42s with a flat spring spring-over.

Since you wont take a picture of your setup, I a simply assuming that you have too much angle and too long of a driveshaft and it bottoms out in the Ujoint cup.

I have a 1310 joint at the bottom of my front axle and a Toyota Ujoint at the top. I have long, long splines and all that keeps it from binding at full droop. No CV.

i understand now that the binding will be worse, but there has to be a way around it ...there always is ,,

SHow me what you have and hopefully I and others can help

I think you misunderstand what folks have said. I know a TON of Cruisers with toasted, flat stock springs, shackle reversal and no binding.

The fact that you said you have standard shackle setup and your drivesahft is binding leads us to say, if you do a Shackle Reversal now, you will get worse binding because something up there is bad and the SR will just make it worse.

TAKE SOME PICTURES like Woody described above and we will get you fixed up.

ok thanks ive been meanin to get pics up but ive been outa town for about a week so. ill get pics up asap thanks guys
 
this is a pic of the front end /......i tried to get a good pic of the angles
cruiser axle.webp
 
it looks like full droop might have enough movement at the top, can you grind on the ears and such to get it to work?

exhaust nice and short, LOL.
 
If you're in Walnut- I can stop and look at it sometime with you, my wife's family lives in Dixon and we'll be there sometime for the holidays, Let me know, Luke
 
hey luke ..that sounds good to me... ill be going to st.louis for a bit during the holidays but if ya want , let me know what your schedule is like and we can set comthin up................................................................................................ i dotn know if i grinf the ears off if ill have enuph clearence it might be real close...wouls it be a good idea to just put a cv on it and let'er be?
 
I think that I should see it before I give any advice at all... I'm having trouble picturing what the problem is from the pictures and the description. Once I know when we're headed that way, I'll send you an email and see if that works for you or not. I'm not promising that I'll have all the answers, but maybe I can be helpful. Luke
 
does anyone know the best thing to do with the driveshaft to make it hook up without binding????HELP!!!!!!!!!!!! :bounce: :beer:
 
Where is it binding? which ujoint?

Right now i do not see any bind issues visually.

I have no bind issues, no SR, soa, no CV, a auto so driveshaft could be longer.

is the above pic with weight? looks like it.
 
My best suggestion is to lower that rig some. If you are building a rockcrawler / trail rig, it's too tall and will be top heavy.

If you are building a mud runner or something that doesn't need much flex, then limit the droop so it does not bind and you will be fine.

If you are insistent that you need to be that tall with that short of a front driveline - call Jess at High Angle Driveline and shell out the bones for a high angle driveshaft. That one is not beyond hope of him making something work.

You can also lower the engine (leaving the tranny in place) and improve the front driveline angle, but I have no clue on if that will worsen the rear at the same time to where it just moves the problem.

Bottom line, in my opinion, you have raised it a bunch and maybe too much for the length of the front driveline.
