Once load shifts occur from cargo weight, braking, or uneven road surfaces, air inside the spring compresses or expands to accommodate movement. This action allows the suspension system to react dynamically without relying on metal spring deflection. Air is supplied and released through the suspension control system as driving conditions change. The spring continuously adapts to load variation while the vehicle is in motion. Pressure changes influence how the axle moves relative to the frame. The TRP RF472491959 functions as a load-responsive air spring within air suspension systems.
