Firestone Air Spring - Double Convoluted, 2 Lobes, 4.1 in Compressed Length

#FIRW01-358-6948

Product Overview


Although air springs are produced in single, double, and triple convoluted and reversible sleeve styles, only those manufactured by Firestone Industrial Products Company bear the trademark “Airide™.” Airide springs were pioneered and perfected by Firestone, and only Firestone offers a complete line of Airide springs, with replacement springs available for virtually every vehicular air suspension system. Today, Airide springs are used by practically all manufacturers who offer air suspension on their vehicles. While it may appear simple, an air spring is actually a highly sophisticated and complex product. Even slight changes in design, methods of construction, or materials used can make vast and significant differences in performance. It makes good sense to specify Airide springs by Firestone. That trade name on an air spring guarantees you the benefit of the very latest technical developments and improvements. It is your assurance of a product not only engineered and perfected to perform, but which also has a long history of superior performance in actual use.Air Spring, Double Convoluted Air Spring, 4.1 in Compressed Length, 8.88 in Width
