This is a Genuine Paccar cab air spring (air bag) service kit used on the rear cab suspension of certain Kenworth and Peterbilt sleeper cabs.
It acts as a pneumatic mount that isolates the cab from frame vibrations, improving ride comfort and reducing driver fatigue. Replace it when the rubber bellows develop leaks, the cab sags or sits unevenly, or the air suspension fails to hold pressure.
Verify your cab suspension configuration and air spring location before ordering. Different Paccar cab air springs (e.g., T81-6000, T81-6002) appear visually similar but use different mounts.
