What weight shock oil to use?

[PowerJoe]

I am going to rebuild my Zero Pro shocks on my M7 and was wondering what came in the shocks from the factory. I was planning to use a 5wt synthetic oil guessing that's what the Arctic Cat stuff is. Does anyone know? Any recommendations on what to use? I have plenty of 5wt fork oil lying around for my dirt bikes and was planning to use that.

Thanks!

I'm no expert but the guys I know rebuiling them usually use Syn. Ams 10 weight.
