Air Spring

The AirTech 3813 is a rubber truck air spring designed for use in commercial vehicle suspension systems. It is manufactured to be a direct replacement for various OEM and aftermarket air springs, ensuring a proper fit and function within the existing suspension setup. This air spring is built to withstand the demands of heavy-duty applications. The rubber bellows are constructed with multiple layers, including cord-reinforced fabrics, designed to maintain flexibility and durability across a range of temperatures, down to -65F. The steel piston and cover plate assembly ensure maximum strength and longevity. Each unit undergoes a 100% leak test before shipment to guarantee quality and performance. The AirTech 3813 serves as a cross-reference for numerous part numbers from manufacturers such as Firestone (1T19L-11, W01 358 9122), Goodyear (1R13-038), and various OEM suppliers like Navistar and Hendrickson. This extensive cross-referencing capability highlights its compatibility with a wide array of truck and trailer air suspension systems.
