I finally found an on-line coil spring chart. Check this out

http://bbb-carb.com/moog_Coil_Springs.htm

I copied and pasted it into a spreadsheet and can sort it to make things easier.

Anyway, I'm trying to choose between the 5409 and 5401. Both have the same load height, but the 5409 has a higher spring rate. As I understand it, the higher spring rate should keep it from compressing as much as the lower spring rate. However, most likely means a stiffer ride.

I'm leaning toward the 5409, since I don't have a lot of room for upward movement of the rear axle.

Do I understand the chart correctly?

Yes, ride height will be about the same, the 5401 will deflect less on a bump. I had about 2" on my 48 chevy, I used urethane jounce bumpers because at times it would bottom out.

Do you mean the 5409? I would think the higher spring rate would deflect less.

You are right, I thought 5409, I typed 5401. :D
