Description
Genuine Firestone Airide replacement air spring W01-358-9825 enhances performance and ride comfort to reduce driver fatigue and discomfort. Replaces Tuthill Granning 700136-01. Firestone bellows number 1T19LE8. Airide springs can reduce your costs and increase your profits. They last at least twice, and as much as four times longer than steel springs, require little or no maintenance, and increase life of tires and brake linings. They substantially reduce breakage and maintenance of other vehicle components, including electrical, air conditioning, cab mounts, exhaust, chassis, seals, wiring and drive train. Airide springs let you haul anything, eliminate expensive deadheading runs, reduce driver discomfort and dangerous fatigue, and improve driver safety, productivity and loyalty. They allow perfect load equalization between axles, letting you run at the maximum legal limit. They provide a smoother ride for payload, reducing costly insurance claims and the expense of overpackaging. Trucks and trailers with air suspensions are worth more at trade-in time. 100% of all air spring assemblies are pressure tested before they leave Firestone's factory. They come with a 2 year / 200,000 mile warranty. Firestone is the original designer of composite pistons. Firestone rubber compounds have superior 'flex' range through temperatures of -65 F to 135 F. Airide springs are available in single, double and triple convolution types plus reversible sleeve models for virtually every conceivable heavy-duty vehicle suspension application. Key components include a stud (permanent part of bead plate for strength), combo stud (mounting and air entrance), blind nut (alternative mounting), air fitting (1/4 N.P.T. air entrance), bead plate (crimped onto bellows for durability and leakproof testing), bellows (four plies: inner, two cord-reinforced fabric, outer cover, natural rubber for -65F functionality), bumper (solid rubber/plastic to prevent damage from air loss), piston (lower mounting, controls spring characteristics), piston bolt (attaches piston to bellows, sometimes extends for vehicle attachment), and girdle hoop (wire-wound ring for lateral stability in convoluted springs). Firestone also offers a composite fiberglass reinforced plastic piston for bus suspensions, which are lighter, more impact-resistant, impervious to corrosion, water, salt, and ice-melting chemicals, and provide a smoother surface for longer bellows life.
