Description
World American WA02-7206C is a sleeve-style cab air spring that replaces Freightliner 18-29919-000 and Firestone W02-358-7206 / W02-377-7202 on Freightliner Century Class and Argosy COE (2002 and earlier). Designed for the cab-suspension mount behind the seat, it isolates driver-side road and engine vibration from the cab interior with a 5.00″ design height and a composite bottom plate using a single push-to-connect air port.
Signs You Need a New Cab Air Spring
- Cab sitting low on one side or sagging when parked overnight
- Excessive cab bounce, side-to-side roll, or harsh impacts over expansion joints
- Air compressor cycling more often to hold cab height
- Visible bellows cracking, dry rot, or bubble leak when soap-tested at the air port

Cab air springs should be replaced as a left/right pair to keep the cab level. Verify the existing OEM number stamped on your old bag (Freightliner 18-29919-000 or Firestone W02-358-7206) before ordering — Century and Argosy used several different cab-mount bags across model years.
