Firestone Air Bag/Piston Assembly
The Firestone Air Bag/Piston Assembly provides controlled cushioning for suspension systems that rely on air-spring dynamics to balance ride quality and load distribution. This sleeve-type unit uses a shaped top and bottom plate to promote smooth compression and rebound as road conditions change. Its build supports consistent height management, helping reduce harsh feedback that can travel through the frame during heavy hauling or uneven terrain. The materials used in its construction are selected for resilience, giving the assembly the flexibility to cycle repeatedly without losing structural integrity. The Firestone W01-377-8537’s dimensional profile also allows the spring to integrate with systems that depend on stable air volume during suspension travel.
