The airbag suspension system uses a system of inflatable airbags filled with compressed air to suspend the vehicle off the ground. Air compressors provide air to the integral components of your vehicle's air ride suspension, keeping air springs and air shocks inflated to a necessary height based on your carrying load, towing, and passengers. A properly working air suspension will keep your vehicle's ride a smoother, more enjoyable one, and help with vehicle stability, braking, and fuel economy.
