As I understand it, there is an air line that connects the front air shocks to each other. This air line contains a "Front Gate Solenoid". When one front wheel tries to go over a bump, as the wheel rebounds and the shock collapses the air pressure can escape over to the opposite shock. This lets the wheel going over the bump to come up easier for a better ride.
But if you are going around a curve, there is a pressure switch within the power steering system that lets the air ride controller know the vehicle is turning. The air ride controller then turns the front gate solenoid on which effectively disconnects the front shocks from each other. As the veicle attempts to lean to the outside of the turn the air in the outside front shock can't escape to the other side so it keeps the vehicle from excessive lean in turns. (If the air was allowed to escape to the opposite shock it would help the vehicle to lean excessively.)
I think a similar process takes place with the rear air bags. Seems pretty cool. Like having an extra sway bar when you need it and not having one to ruin the ride when it's not needed.

The front air shocks are part of the air ride suspension system that basically consists of the front air shocks, rear air springs, ride hight sensors, and a compressor mounted in front of the widow washer fluid reservoir. It automatically adjusts the suspension to improve handling of the vehicle. If it's all working, I'd leave it alone. If you do choose to remove it you'll need to get the conversions like these ones www.SuncoreIndustries.com if you do the front you'll need to do the rear also. These conversions are needed because you can't just swap these out for regular shocks due to the mounting, and springs needed in the conversions to maintain your ride hight.

No. There are height sensors front and rear. Thats why its called LLS (Load Leveling System).
If your running empty, or towing with a heavy tongue weight, or have 5 people in the first two rows of seats, the vehicle will always try to keep a level trim.
One thing about air suspensions is that when they pump up the spring rate increases, and when they vent down the spring rate gets softer.

do you pull the torsion bars out then? it didnt say anything in the directons. why do you need coils and torsion bars?
do they ride better then a standard exp suspension?

i was looking at a non air eb the other day. what is the difference in the suspension in the front other then where and how things mount? this one just had shocks and torsion bars. so why cant i just replace my air shocks with regular shocks? the front air shocks dont act like a coil over like what is on that site
