Shock oil weight preference and shock rebuild kit?

[Deluge]

One last question. Would you replace o ring as well? I assume you would since it's a rebuild. Thanks!

Only if they're damaged. It's a good idea to lube the O-rings, as well. I use this for my O-rings...

You could use AE Green Slime, as well. It's the same thing, and you can probably find it locally.
