HOTROD Let the Air Out Air suspensions for hot rods & classics aren't as daunting as you might think. By S. Kellie Colf A pproximately 96-percent of all semi trucks on the highway use air suspension. That big an industry wouldn't be using them so extensively if there wasn't something to it. Your shop should be offering them as a solution to your customers. But… Myth: Air suspension is not only complicated, but expensive and troublesome. Wrong! The myth continues to prevail around air suspensions that they are mysterious systems fraught with problems and upkeep. This is simply not true. Proper installation of an air suspension system requires no more skill and common sense than working with traditional coil or leaf spring suspensions.

Air offers the ability to change ride characteristics with changing road conditions. Soften it up for a smooth highway ride; stiffen it for more challenging conditions. Stance Is how she sits very important? This means both under driving conditions and when parked. One benefit unique to air is the ability to have multiple stances—one for driving and one for parking. Want her in the weeds? Air can offer that, but you can't keep her on the ground if you ever want to drive her. Air systems offer your customers the ability to drive to the event in comfort with superior handling, and drop her on the ground when they get there. Handling & Performance Is drivability key?
