when we put the chevy shackle on scotts truck i noticed that the shackle is narrower than the hanger.
how this issue is addressed can affect the springs relationship to the frame, and in turn the axles relationship to the centerline of the truck.

IMO, the best option would be a spacer on each side of the shackle to keep it centered in the hanger when the bolt is tightened.

how did you correct the misalignment?

no he means the drivers side tire is further forward than the passenger side tire.

its dog tracking.

front tires / / (forced this way to make it go straight

rear tires / / ( this way because the center pin is in different places than the other side

i see. mark said axle off center, not thrust angle, and mentioned that the rear wheels ARE centered in the openings....guess i misunderstood

anyhow, didnt you see the axle off center on your truck, or is your problem with thrust angle as well?

what did you do about the shackle fitment?

that confirms what i have read, and is exactly the effect i am lookin for. runnin the mondo RCD shackle has pushed my rear wheels forward in relation to the opening. the 3/4" extension of the WB from a chevy swap would fit nicely.

i just tightened the hanger bolt. it was not really an issue.

as for mine its the trust angle as well its off over a 1/4" so im just thinking move the hanger on the drivers side back some.

then again i still think my frame is bent so i might be misunderstanding mark.

idk im cutting the rear half of my frame clean off one of these days.

in that case, i would wonder if the front hanger holes are in identical places along the length of the frame......or dont buy procomp springs.

any thrust angle issues bob?
what about evans truck? since he used stock chevy leafs too.

as far as i know evan has no issues.

his install went flawless. now marks that was a different story.


the lift springs are actually longer on one side of the spring than that other.

i think its the mount. the front one on the drivers side.

lol..

Remeber when we did the swap at your house....We had the springs turned in the wrong direction (cause there is a long end, and a short end of the spring from the center pin) We had one long end facing the front and one long end facing the rear. When i started it up to drive, my steering wheel was cocked 1/2 way just to go straight - almost looked like 4wheel steer. We couldnt figure out what was wrong until we measued the end of the spring to the center pin. Then we figured out the lengths varied, so we flipped one spring around. That helped a little, but my steering wheel was cocked 1/4 of the way to go straight after that.

Then, last fall i had enough of the steering wheel being off, so i put the left leaf on the right side and the right leaf on the left side, and spun both around. When i bolted them up and took it for a spin, the steering wheel was almost perfect, still slightly to the left, but alot better than before. Now lately it seems like it's getting worse - the steering wheel has to be turned a bit to the right to go in a straight line.

Im wondering if the shackles are causing this?

Your truck is doing the same as mine.

My thrust gets thrown off b/c of the locker. When I take corners (mostly ONLY when I take right corners) my steering wheel will go left about 1/16" more every time. if I take a left corner, same thing, it goes right about 1/16".

The only way you can "fix" it (which is a bandaid fix) is to tighten the u-bolts to 100ft/lbs when the axle is dead center. Do this by supporting the truck on jack stands and adjusting the axle. I use fenders as marking points (even though it's not AS accurate as driving it). Mine is near perfect now.

I think maybe if you put some sort of spacer in the pin to make it fit tighter or something it woudl be better. I'm in the process of doing the same. My pin I'm guessing is loose fitting in the center pin.

Chev swap is soon anyway

Mark its not the shackle. if it was everyone would have the same issue with stock springs.

just a guess but mine started to pull to the right before the SAS, the balljoints were going out. might want to jack the front end up and check it out.

No, he is right Zach

After i flipped the springs around i didnt have a good wrench to tighten the u-bolts...I was driving with the back window down one day and noticed a weird clicking noise...So i tightened the shackle bolts, and it still made that weird noise. I was like wtf and went on a tightening craze, after i tightened the u-bolts a bit the noise dissappeared.

I need to loosten the u-bolts, jack the truck up, center the axle, then re-tighten the ubolts.

This sounds like a legitimate issue...

Oh and my truck isint really "pulling" to the right at all. If anything its the left a bit.

well you should have known to tighten them, seems like we used the torq wrench on them before you left.

sounds like u need to take the truck to a good alignment shop.

heres a ride quality question while all you chevy spring swap guys are here.

do the 1500 springs come in different rates for different payload/WB optioned trucks? like say, if i found a short wheelbase 2wd sport, might it have softer springs than a long wheelbase towing package truck, or sumthin similar?

Well this is interesting information. My truck is very heavy in the rear which might help, and I'm not as worried about the spring rate.

What I am concerned about though is the relocation of the front mounting point and the undue flexing caused by the unreinforced mounting point on the one side. I need to think about whether I am doing a swap or not.

I was thinking that.

And also, in response to your other question, yes, jack it up and put it on the frame with jack stands.

just 2wd and 4wd, the 4wd has an extra leaf spring in it. the 4wd you might get some more lift out of it too. idk.
