Looking for air bag and shock replacement parts for your semi-trailer? Utility Keystone can help.
When replacing a faulty air bag on your semi-trailer, you’ll also want to purchase a new air bag mounting kit and possibly new shocks.
Utility Keystone carries Hendrickson and Firestone airbags.

Two ways to identify the specific replacement parts you need for your trailer.
- Provide your parts sales representative with the vin# of the trailer
- Provide your parts sales representative with the model # and serial # of your trailer’s suspension, which is identified on the left front hanger of the suspension itself.
Air Bag Mounting Kits:
Mounting kits can become corroded, requiring them to be cut off when replacing the airbag. Therefore, it’s a good idea to order a new mounting kit.
Shocks:
Consider replacing shocks when replacing airbags. Over time leaking airbags can cause added stress to shocks causing additional wear.
Utility Keystone carries Hendrickson and Pro-Par shocks.
Check for other worn parts:
Check the airbag pedestal and top mounting plate for excessive wear when replacing these wearable suspension items.
