Many performance cars and SUVs come factory-equipped with air suspension. Arnott has been in the business of providing OE-replacement air suspension products for many years, and often the Arnott-engineered air suspension parts are an improvement upon the factory components.
Your factory-installed air suspension uses air springs/air bags instead of conventional steel springs, and an air compressor that inflates and deflates the springs. Most air suspension systems have computer-operated vents on the air springs and suspension sensors. These are complex systems (compared to a conventional coil spring system), and are designed to maintain ride height and vary the suspension's ride characteristics according to the manufacturer's design. When a vehicle with air suspension drops below the factory-defined height, the compressor is activated and inflates the air bags or air struts.
Air springs normally last approximately 80,000 to 100,000 miles. Over time, the rubber bladder dries out, and cracks appear around the bottom piston. Compressors will also wear out because of leaky air springs. The computer and height sensors usually last the life of the vehicle.
Arnott recommends replacing the air dryer when the air suspension system has leaked, because the dryer becomes saturated when the compressor is overworked. Replacing the air dryer will prolong the life of your air compressor and air spring solenoids.
Shockwarehouse carries Arnott air suspension replacement parts for all available applications.
Some of our customers prefer to switch to a coil spring suspension when their air suspension wears out. Learn more about Arnott Coil Spring Conversion Kits here.
