Air Lift 1000 Installation question

[azeagle]

I have a question about installing a Air Lift 1000 system on my 2006 Wrangler Unlimited. I saw a installation video showing the installer just smashing the airbags, and folding each end to get all the air out of them. He then just shoves them into the spring then reenflating. This seems easier than removing the springs completely but is this the correct way to intall them? I need some advice on this please.
