Installing rear coil springs on a Impala SS

[Jim Spahr]

I bought a set of Moog CC507 rear springs and they are progressively wound. They have a section of closely wound coils and a section of coils much further apart. These are called 'cargo springs' because they allow a comfortable ride when lightly loaded and a firmer spring rate when heavily loaded. My question is - do you place the tightly wound coils at the bottom or the top, when mounting them? Or does it matter?

Tighter coils go on top.

Blokley, thanks for the reply and you are correct. I did find a small piece of paper in the bottom of the box of springs. It had some install tips and stated that the tighter coils do go on top. Thanks. Jim
