1T15SM6 RB 2BM 3/4OFF BW AIR SPRING

Firestone Airide springs are designed to reduce costs and increase profits for heavy-duty vehicle operators. They are built to last at least two to four times longer than traditional steel springs and require minimal maintenance. Key benefits include increased tire and brake lining life, reduced breakage of other vehicle components, improved driver comfort and safety, and perfect load equalization. Firestone Airide springs are available in single, double, and triple convolution types, as well as reversible sleeve models, catering to a wide range of heavy-duty vehicle suspension applications. They feature robust components such as permanently attached studs or blind nuts for mounting, 1/4 N.P.T. air fittings, crimped bead plates for durability, and four-ply rubber bellows with cord-reinforced fabric. Some models also incorporate composite pistons, which are lighter, more impact-resistant, and impervious to corrosion compared to steel or aluminum. Common applications include primary trailer suspension, lift axle, drive axle, front axle, cab mount, and seat air springs. All Firestone air spring assemblies undergo pressure testing before leaving the factory and come with a 2-year/200,000-mile warranty. Firestone is recognized as the original designer of composite pistons and uses superior rubber compounds with a wide flex range (-65F to 135F).
