Description
World American WA02-7087C is the aftermarket cab air spring for Freightliner FLD conventionals (1988 and later), replacing Firestone W02-358-7087 and Goodyear 1S5-040. Sleeve-style construction with a 1-stud top plate (2.99″ diameter) and 1-stud bottom plate (3.25″ diameter), 2.4″ compressed and 8.5″ extended, rated to 100 PSI. Mounts under the cab corner to isolate the cab from the chassis.
Signs You Need a New Cab Air Spring
- Cab leans to one side at rest, or sits low until air builds
- Audible air leak from the cab corner area; air system cycles repeatedly when parked
- Visible cracks, blistering, or tears in the rubber sleeve, or rust streaks from a leaking bead
- Harsh ride quality, sharp impacts felt through the cab over expansion joints
- Cab makes a clunk or knock over bumps from a collapsed or unseated spring

Applications

Replace cab air springs in pairs (left and right) when one fails — a single new spring next to a worn one will sit unevenly and the cab will rock asymmetrically.
Verify your cab mount configuration (stud pattern, hose port location, and top plate orientation) against the failed unit before ordering. Class 8 cabs use several similar-looking sleeve air springs that are not interchangeable.
