I recently purchased back a '55 BelAir 2 door sedan that I sold in 1991.
It had a broken rear spring, so I ordered a set of new 5 leaf springs from
a 55-57 Chevy vendor I've been dealing with for many years.
The new springs have much thinner leaves than the old ones,
such that we had to order new u-bolts from another vendor,
because the ones on the car were too long.
Has anyone else noticed this ?
After installing the new springs and gas shocks,
the car initially sat a bit higher in the rear - now after only
about 2 months, the car is sitting level, or perhaps even a
little lower in the rear.
A friend suggested a set of "Helper Springs" - any opinions ?

I spoke with my vendor today, and he said he has been selling
springs from this distributor for almost 20 years,
and never had anyone else raise this concern.
Am I the only person who has experienced this ?

I'd be very interested in hearing the dimensions of other members'
rear springs - how thick is each leaf, what is overall thickness of
the spring, and how does the car sit - level, slight rake,
or down in rear.

Thanks - Rich Warner - MisterShine

I replaced my leaf springs last year and didn't notice any difference in thickness. I could measure them for you if you want me to, but there wasn't anything unusual that I noticed.

I just went to the garage. My rear springs are 2 inches wide and 3/8 of an inch thick. These are the springs that were on the car when I got it last fall. They are 4 leaf and because there was no engine or trans the nose was higher than the rear. I believe that these may be originals as they have a different look than what you see on springs these days. I have a '56 210 2dr sedan.

Tickness of replacement 5 leaf springs

Update: A friend of mine was looking under my car because he also
noticed that it was not sitting as high as it was when the springs
were changed about 2 months ago. He said they match the description
he saw in someone's catalog (he can't remember what vendor's catalog
it was) - they were referred to as "soft ride springs".

One 55-57 vendor catalog I have says the following about the
replacement rear springs they sell:

"We will sell only 2 multi-leaf springs both made in USA"
"These won't *** out after a few months"
=> Sounds like thats what happened to my springs...
This vendor sells both their 4 leaf, and their 5 leaf springs for $129 each.
I paid $100 each - I guess I got what I paid for...

I'd be very appreciative if a couple/few of you who do have 5 leaf
replacement springs, could measure the thickness of the individual
leaves, and the overall thickness. I think I'm going to have to spend
the money, and the effort to change out these springs,
for the ones I noted above.

I just went out to my garage, and measured my springs.
The longest/full leaf measures about 5/16" thick,
and the total spring at the center, measures about 1 9/16" thick.

Thanks very much - Rich www.mr-shine.com

Rear Springs - Thickness ?

I'd be very appreciative if a couple/few of you who do have 5 leaf
replacement springs, could measure the thickness of the individual
leaves, and the overall thickness. I think I'm going to have to spend
the money, and the effort to change out these springs,
but I'd like to confirm what I suspect - that my springs are not as
thick as some other replacement springs.

Thanks very much - Rich

I heard somewhere that the rear shackle can get "reversed" or "inverted" or something, and might have an effect on the way the car sits. Take a look to make sure they're positioned right.

Rear Springs

"1957Chevy":

Thanks, but the shackles are definitely in correctly.

The car did sit higher in the rear right after the new springs/shackles
were installed, then it slowly (over 1-2 months) settled in to
a lower stance. I'm convinced that these springs are different
from the ones offered for $129 each - where this vendor specifically
mentions that these springs "don't *** out after a few months".

So far nobody has gotten back to me with a measurement
of their springs.

Thanks - Rich

Not to beat a dead horse, but I heard that the shackles get flipped or whatever after they've been installed correctly. I'm not saying this it your problem, but it's something that's easy to check -- just take a look and make sure they didn't flip.

I have four-leaf springs, but I'll still measure them for you for what it's worth.

I found a piece of an old, I think "original," leaf that was on the car when I got it. It is part of a four-leaf spring -- it measures 2" wide by 5/16" thick, which is exactly the size of my new four-leaf springs.
