This refers to a specialized suspension system designed for the front axle of Peterbilt 379 model trucks. It replaces the traditional leaf spring suspension with air springs (also known as airbags), providing a cushion of compressed air to absorb road shocks. A complete assembly includes the air springs, mounting brackets, air lines, height control valves, and related hardware necessary for installation on this specific truck model.
The integration of this system offers enhanced ride quality, reducing driver fatigue and improving the lifespan of vehicle components by minimizing vibration. Furthermore, it can contribute to better handling and stability, especially when carrying heavy loads. Historically, such systems have been implemented to address the demand for increased comfort and improved load management in heavy-duty trucking applications.
