An air spring bag is a hollow inflatable rubber bag. They are used in place of coil steel springs. Air bags are flexible and have a certain amount of give, this helps absorb bumps for a smoother ride. Suncore Industries air bag suspension parts are engineered to last at least 10 year. When replacing an air spring bag with a Suncore Industries air bag you will be doing so at a fraction of the cost, when compared to OEM costs.
