The Hendrickson C-21210-1 or C212101 is an air spring for an air suspension. An air spring is the flexible rubber bellow that holds the air cushion carrying the load between axle and frame, so it sets both ride height and load support. A worn bellow shows cracking with cord visible through the rubber, a hole rubbed into its side, bulges, or air leaks, and it is best changed before it fails on the road. A genuine Hendrickson part from Pro Gear and Transmission. Call us with your suspension model to confirm proper fit.
