Hi all. Hope everyone is well out there.

I know the subject of coil spring rate color codes have been discussed before but I can't seem to find it.

I have two coil-over springs (sitting on my shelf for the past 10 years) for which I am trying to confirm the spring rates.

They are black powder coated springs, 3.4" OD by 2.6" ID by 8" long. There are two color slashes on the end of the springs: silver and red.

I don't recall the manufacturer but my hand written numbers on the end of the spring say 450 lb.

Is there a site/reference I can go to to confirm the color code/spring rate.

Cheers
Greg
