ahhh.. so that's it.. nitrogen pressure.. makes sense.. so I suppose I just have to mount them and just pump them up to the desired ride height?

What would you recommend alwaysbroken, Should I mount them half way extended, fully extended or... ?

I've noticed that everyone seems to mount them about 6" from being completely colapsed.. that doesn't make much sense to me because i'd imagine you'd want maximum up and down travel thus mounting them at full stroke and then pumping the nitrogen in until they're about half way.

Any suggestions!  I'm a complete newb when it comes to Air Shocks
