Will this settle?

What do you think? I just installed new eaton monoleaf springs and poly bushings. I think it is sitting a little high. I don't have the rear shackles tight yet. The gas tank and interior are out so the full weight is not on the springs yet. Should I go ahead and tighten the shackles or wait till I get more weight on the springs.

YIKES ! That looks awfully high.

What happens when you add 150 pounds or so to the back end?

Have someone of about that weight sit on the rear of the car and see how much it squats.

P.S.

A gallon of Gasoline weighs aprox 6.5 pounds.

18 gallon tank full would be aprox 117/lbs plus the tank weight.

Re: Will this settle?

Doug - If I (180 lbs) sit on the trunk, it drops about an inch (not as much as I would like). Addiing the gas tank and gas would not even be that much weight. It sounds like adding weight is not going to get me where I need to be. Any suggestions on getting it lower?

Re: Will this settle?

something doesn't look right to me... did you tighten the shackles with weight on them? put it back on the ground have someone sit in the trunk, loosen the shackle bolts, bounce it around and retighten everything.

Re: Will this settle?

Steve: The shackle bolts are not tight yet. I put it on the ground, bounced the rear of the car up and down a dozen times and this is how she looks. I tightened the bolts on the spring perches at the front of the springs before I attached them to the car. The assembly manual says that is OK. Only the shackle bolts need to be tightened after the weight of the car is on them; is that right?

My suggestions were to see what it might end up like once you finished putting the tank (full of fuel) in.

If your 180lbs only moves it an inch i'd be really worried that you got the wrong springs.

Re: Will this settle?

I purchased these Eaton springs through Rick's (At the time it was cheaper than getting them directly from Eaton). I have contacted Rick's about them and even sent them a picture. I will keep you posted on what I learn. I remember a number being stamped on the springs, but of course that is now covered by the rear mounting plates. All I want is to reproduce the original stance. I had to replace my original monos because the left spring was broken at the front perch.

Re: Will this settle?

Here is what I have learned. Both Eaton and Rick's responded very promptly to my Email questions. The coupe mono leaf springs are Eaton ML001 and should have a free arch of 6.25 inches. Mike from Eaton says it is possible I have the Eaton ML002 springs for a convertible. Their free arch should be about 2 inches higher. That seems logical.

I will need to remove one of the springs tonight and measure the free arch to determine which one I have. If they are incorrect, Rick's is willing to swap for the correct ones. My fear is that they are the correct ML001 springs. If that is the case, then what do I do?

Rick's suggests that adding the gas tank and interior is much more than my 180 lbs sitting on the trunk and that the body height should look fine once that is done.

Does anyone have experience with adding new springs without the weight of the interior and gas tank? Should I expect to see a 2-3 inch drop when my restoration is done?

Re: Will this settle?

I had the gas tank and entire interior out of my car before I swapped my springs. They were no where near as high as yours. Can you post a pic of the rearend where the springs are mounted?

Re: Will this settle?

Mikey: Here you go.


I pulled one of the springs off last night and measured it. The arch measured 6 5/8 inches. Mike at Eaton says it should be 6 1/4 inches. The spring also had ML001 stamped on it next to the centering knob. So these are the right springs for a 67 coupe. Rick's was very cooperative about replacing them. I have decided to wait until I get the car completely back together before seeing if I want to try a different set of springs. De-arching these springs is also a solution listed in a couple threads CamaroDave told me about (thanks Dave).

After putting the spring back on last night, my 18 year old son and I sat on the trunk and the ride height was almost where I want it. It moves quite a bit because the shackles are still not tight, so adding the weight of the interior, gas tank, gas, spare etc. may get it to the right height. I just have to remember to tighten those shackles before I drive it and at my rate of restoration that will be over a year from now.
