My current project has a discernible 1/2" left lean at the rear. Right front is equivalently high. Apparently the previous owner used a torch on new springs to drop front down at least an inch...but missed the mark a bit on the right front.

I have replaced all rear spring hangers, pads, bushings, shackles.

Advice is requested: do I take my torch and heat the coil which is most collapsed and if so, where on it and how do I limit the amount of drop?

Or do I have to bite the bullet and buy new coils, which may or may not need some massaging?

I think your aware, the back can still cause the front to appear to sag. Determine if it's the front or back by jacking the front up on a pipe running longways in the exact middle of the front crossmember. Then measure the back from the frame to the axle housing. http://www.trifive.com/garage/56%20Chevy%20A ssembl...

I would use Acardon's method after I changed the front springs. Reason is with heating a spring you heat/weaken areas in both directions past where you aimed the torch. Even if the car sat 100% square now I would still switch out those front coils.
Or if you have not heated coils b4 do Acardon's method first then heat up the rt coil and watch for results. Don't let shock get too warm.
Report back once you get the fire knocked down.

Torching coil springs is absolutely the worst method available. Don't do it. Worst ride and tire wear. Drop spindles is the only method that doesn't mess up the steering geometry.

The problem with torching the springs is twofold.

First, it's nowhere near exact on the results as you already know.

Second, the spring is heat treated - except the part that's been torched. That part will continue to change with time and use.

Just get some new springs and if the ride height is too tall, cut coils to make a fine adjustment. Or put a rubber spacer under the spring if too low, for a fine adjustment. Even original stock springs are fine as long as they don't have pitted rust. Contrary to popular belief, they don't change over time without intervention.

Now that you've posted an ad, I'll post a counterpoint.

A guy I know bought some Eaton Detroit springs for the front of his 57 a few years ago. The ride height was too short, not necessarily the look but the tires rubbed the fenders. He decided recently he'd had enough, ordered some new springs from them to raise the front. First set he got raised it too much. Sent them back, next set raised the front even more (gasser look, not what he wanted). Throughout the whole process, they told him how stupid he was.

He now has a rubber coil spring spacer under the original replacements and it's doing pretty good. Still low stance but not rubbing, what he wanted.

FWIW, here is my experience with Eaton Spring. I purchased some rear leaf springs form one of the low cost catalog parts sellers and they failed very quickly. I then ordered some from Eaton and after talking with the sales rep, we decided on a spring for my car. I wanted the ride to be stiffer and the car to sit lower. The springs were perfect and have been for about 10 years of use.

Something I heard about the company is that the founder has passed on and the company is now run by his heirs. Things may not be what they once were.

I do know this. I called them several years ago and I was not satisfied with what I heard on the other end. The guy I talked to seemed to care less about my needs or whether he even sold me anything. I declined to buy anything.

Tri5man and Rick did I lead you two to think I was suggesting heating a spring as a fix rather than a lesson if you had never done it? Since the springs had been heated b4 I saw them as just junk to be pitched.
I know there is a Moog listing of springs here in CT somewhere but I am drawing a blank. Either of you know where?

Larry:
I purchased front coil springs from them around sixteen years ago (3" drop). As I remember they were very professional. Still driving with them on the car as of today.
This was a long time ago, some thing change and some things don't.
