Can anyone help me with what primary springs these are?

[snowmanx]

I've got 4 primary springs that are used on an arctic cat primary.

From left to right,

1st is a titanium blue

2nd is a titanium yellow/green, pretty sure that is the stock spring on a KK

3rd is a yellow/white...M1000 spring?

Last is gold? Is this a CPC primary?

If you know the rate of each perspective spring that would be great.
Thanks again for the help.

The Yellow/White is 122-285 lb (AC P/N 0646-229)
The Gold is 75-275 lb (AC P/N 0646-376)

The 1st one, titanium blue is the 440 sno-pro modified, but I still don't know the rates.

The 2nd one is indeed AC on the KK, but again, I can't find the rates.


Are you sure about the gold spring rates? It seems stiffer, not softer than the yellow/white when I try to compress them manually.

Anyone else have any ideas?

Thanks

What I do is take a bathroom scale and set it on the drill press table. Then use the drill press to compress the spring. It is an easy way to check the load at different compression levels.

Another interesting thing. It is a good idea to take a new spring and check it. Then compare it to what you are running.

Example: You are running a 130/300 primary spring. You purchase a new 120/320 primary spring. You switch them and you don't get the results you expected. After checking the new spring it is actually running more like a 120/305. So you can really chase your tail if you don't know exactly what your new spring is compaired your old spring.
