From the posts that I have read and from doing searches when measuring the spring with no load, track off the ground all the post mention spring length at 10 3/8". I was trying to do this adjustment yesterday to get ready for winter and the spring that I have on the used Attak that I bought is 12 3/4" long and after checking it with me sitting on it the spring length is 11 1/4" so it is even to long with a load on it. Is this a different spring than stock or am I measuring it incorretly? If this is a heavier spring is there a way to be able to tell which spring it is? Any information would be greatly appreciated.

What model of suspension do you have and which shock are you talking about? Oh, ... Maybe you could go to your profile and list this type info. Then it would automatically be there for you, all the time.
Not sure about your overall measurements but the 1 1/2" difference in spring length (called spring sag or set-in) when you sit on it is close to being right on, if correct I'd leave it.
Monoshock ride height is set by measuring the spring completely unloaded, then again with the weight of the sled and rider, just as you've done. Difference should be 40~45mm. You're at 1.5" / 38mm, a little on the stiff side, but when you add gas, riding gear, snow and ice you're probably right on.
If it still feels too stiff in real-world riding, back off the spring preload until you get 1 3/4" / 45mm of sag and try it again.
The 40~45mm spec is the same for both shock types and suspension lengths, 121 or 136", Kayaba or Ohlins, so it's easy to remember.

Thank you type787x. I guess the overall length really doesn't matter as long as you can acheive the correct overall measurement.
