Built with Firestone Airide construction, this assembly uses a 1T15MT-8 bellows with a 9-inch top plate, 10-inch piston, and a compressed height near 5.9 inches for compact suspension movement. Its approximately 22-inch extended height provides the travel range needed as axle position changes under load and road input. The Firestone W01-358-9648 air spring’s reversible sleeve design helps manage vibration transfer while supporting stable suspension operation in matched applications.
