Aibags are a great option. I have the chevy airlift bags on my truck. the problem I have with them is they are my only source of lift. If they fail off-road then my lift does too. they could fail from exhaust heat, line being pinched, or a bag busting, ( even though I have never heard of a bag busting) still possible. Plus when I get passed 2" lift or so with them the ride gets too rough. Bouncing around everywhere. I plan on using them with my new springs as a load leveler only.
