Hendrickson air spring 66975-000 or 66975000 is a suspension part and a genuine Hendrickson part from Pro Gear and Transmission. An air spring is a rubber bellows filled with compressed air that carries the load and sets the ride height of the suspension, so it keeps load support steady over rough roads and heavy loads.
When a bag cracks or leaks, a corner or axle settles low, often after the vehicle has sat parked for a while. Dry spots, cracks in the rubber and contamination from oil or road debris are the visible cues that a bag is nearing the end of its life. Call us to confirm proper fit for your suspension.
