Just curious if there is a telltale way to find ones current spring rate? Mine are all black springs, does the blue on yours make them 150 lbs?

Yeah, black paint is stiffer than blue paint.


(actually there should be some numbers on the springs)

The easiest way is to apply a known force and measure the deflection. I picked up springs from southern speed and they only have a small aluminum band with the spring rate. Once that frees itself from the spring there is no easy way to find the spring rate other than applying a load and measuring. And for the record, they're painted black.

Check the end of the spring, you may have the rate etched into the flat ground section of the last coil.
I actually have a spring checking fixture, but a bath scale and drill press could be rigged up, so it could be used on these lite springs to determine the rate.

There are various on-line calculators that are damned accurate. Needed is a micrometer for measuring the wire diameter, a tape measure to measure coil diameter and an ability to count the number of active turns. I used one calculator to determine the spring rate of my springs. Later when I removed the spring, I found the exact same rating written on it.

IIRC, all GAZ springs are stamped with the inch/pound rate, on the flat plane at the top. You may have to look close - the paint may have partially filled in the stamping.
