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 the 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. These springs allow perfect load equalization between axles, reduce driver discomfort and dangerous fatigue, improve driver safety, productivity, and loyalty. They provide a smoother ride for the payload, reducing costly insurance claims and the expense of overpackaging. They pay you back at trade-in time; trucks and trailers with air suspensions are worth more. 100% of all air spring assemblies are pressure tested before they leave Firestone's factory and 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.
