Firestone Double Convoluted Air Spring
The Firestone Double Convoluted Air Spring serves as the primary lift mechanism for Hendrickson, Ridewell, and Watson & Chalin suspension systems. This Firestone W013586910 (Style 20) uses a two-ply fabric-reinforced bellows to provide a 2,720 lb load capacity at 100 PSI while maintaining a compact 3.12-inch compressed height. The top and bottom bead plates feature 3/8-16 blind nuts spaced 3.5 inches center-to-center, ensuring a secure mount that won't swivel or leak under high vertical oscillation. Its double-convoluted geometry allows for a maximum extension of 9.9 inches, providing the significant stroke required for lift axles without the risk of sidewall "ballooning" or structural failure.
