advice needed for shock replacement

[accely]

Hey all, new to the forum, had my 04 H2 since 2010 summer. love it!!

My H2 is at 100k miles and it's still on stock shocks & suspension so the ride seems a little rougher than I'm sure it could be with some new parts.

I'm primarily interested in making it a softer ride for daily driving. Suspension lift kit may come later. So I'm looking for suggestions on what to do. Would it be as easy as replacing stock shocks? should I check out aftermarket shocks? I was looking at Rancho rear/front shocks for around 50$ each one on a few sites.

Also, can someone explain the air ride suspension for me? How do I know if my H2 has it? If it doesn't, can it be installed?

Thanks guys.

Dan
