A suspension system is comprised of shock absorbers and coil springs which connect the frame to wheels, allowing for relative motion. When you drive on a bumpy road, suspensions deduct vibration efficiently. Stance, handing, riding height and riding performance of your vehicle are affected by suspension system entirely. Air bags, say, air springs which are precisely designed rubber bellows. Allow people to change the air pressure that air bags sustained to get a perfect stance, better handing, proper riding height and splendid riding performance with just a single touch of a button .
