A system employing four control arms to locate the axle and air springs for damping and height adjustability represents an advanced form of vehicle suspension. This design replaces traditional leaf springs or coil springs with inflatable air bladders, allowing for a customizable ride experience. One practical application is in custom trucks or performance cars where the driver desires adjustable ride height and improved handling characteristics.
The integration of this type of suspension offers significant advantages, including improved ride quality, load-leveling capabilities, and the ability to alter vehicle stance. Historically, it evolved from heavy-duty applications in trucks and buses to become a popular modification for enthusiasts seeking enhanced performance and aesthetics. The ability to adjust the air pressure within the springs provides a versatile solution for varying load conditions and driving preferences.
