Hi,

I have a 1956 Bel air 4 door.

I think the rear springs are original to the car, and they are sagging.

What springs would you recommend for this application?
The springs in there now are 4 leaf springs. Was that original to the car?
Would 5 leaf springs be a better and safer bet?

Thanks.

The five leaf replacements will make for a stiffer ride and set the rear end up higher.
If it were mine I would stay with the four leaf as the newer replacements do not tend to sag as much.

Ok, thanks.
Just curious, are the 5 leaf springs a dangerously stiff ride? I don't want the 5 leaf springs to make the rear look ridiculously high....is that the case in your opinion?

Spring rate (stiffness) is different that load capacity and height.

If everything else (spring length, leaf width and thickness) is the same a 5 leaf spring will be about 20 to 25% stiffer than a 4 leaf. The 5 leaf spring can be designed and built to give the same unloaded ride height as the 4 leaf. Under the same load the 5 leaf will not settle as much.

see if there is a spring shop in your locale that can re-arch your original springs. there is a shop in Frostburg, Md that I've used in the past, successfully. mike mccagh

I had the springs from my 32 re-arched 22 years ago and after 12 thousand miles they are still fine. I think much depends on the ability of the shop doing the work and the condition of the springs to start with.
