C-21220-1 or C212201 is a Hendrickson air spring. In an air suspension the air springs cushion the ride for the driver, the truck and the load, working together with the shock absorbers. The rubber tends to age out before it wears out, and checking the flexing rolling lobe for cracks and sideways splits is the main inspection; a leak starts once the cracking reaches the inner liner. Call us to confirm proper fit for your suspension. A genuine Hendrickson part from Pro Gear and Transmission.
