A specialized suspension component designed for specific heavy-duty trucks, it replaces the conventional leaf spring system on the front axle with air springs. This modification provides enhanced cushioning and ride quality, tailored for the Kenworth W900 model.
This system’s adoption offers several advantages, including improved driver comfort, reduced chassis stress, and potentially longer component lifespan due to decreased vibration. Historically, such systems evolved from efforts to mitigate road-induced fatigue and improve load stability in commercial vehicles.
