I have new multi 5 leaf springs from eaton springs.(this is not a conversion, it had 5 leaf multis before), new shackles , and new spring perches and bushings.
After bolting up the front spring perches, I tried to swing the new leaf springs up to the rear shackles to test fit.
Problem:
The leafs barely reach the rear lower shackle bolt hole. by barely I mean I was not able to get the lower bolt in. I may be able to if I torque the heck of it.
Even then the spring eye will be right up against the rear frame rail bottom.
Is this normal and will this PUSH OUT with weight on the springs. Seems like the weight would push the spring tighter against the frame rail.
I know the old springs were about an inch longer but were sagged out and had a couple leafs broken.
I have compared new and old shackles and the hole in the shackles plates are the same.
I am kinda stuck on if I should proceed and this is normal and will straighten out OR something is not right.

Thanks

Not sure whats going on there. But I just did mine and started from the shackle then push the perch up in to the body. I even used a small car jack to hold the spring and slowley raise it up. Its nice b/c you can move it around an such to align the bolt holes and lip with out having to hold the weight of the spring all the time. Dont forget to leave the shackles loose while you do this.
And yes the spring will flatten out some. Mine had a pretty fair arc (being brand new) but once the cars on them it will sit much better. Good Luck.

Hi spideynut
Did you have any play in the hookup at all. Mine will have to be forced for me to get the rear bolts in. My difference is I have Competition Engineering Sub frame connectors as well as the spring perches already bolted up. I'm trying to do the shackle side last.

I think I'm OK, I went out this morning and rigged up the floor jack under the springs. If I put pressure under the spring I can force the EYE out far enough to slip the bolt in. With weight on the car it should push the shackles down to I hope proper position.

Thanks

so you have the springs mounted on both sides? if so yes the rear shackles will sit where they may once the car is on the ground.
