An air spring is a heavy-duty rubber bellows that works like a high‑pressure balloon to support a truck’s front or rear axle.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
Compressed air inside the bellows takes the place of traditional steel springs, automatically adjusting to load and road conditions to keep the chassis at the correct ride height. As the air spring flexes millions of times, the rubber can crack, leak at crimped seams, or de‑laminate, causing sag, rough ride, and uneven tire wear. Replacing a worn air spring restores ride quality, stable steering, and proper suspension geometry, preventing damage to shock absorbers and linkages.
