RQN500070LR - Air Suspension ReservoirDescription: Air Suspension Reservoir for the Electronic Air Suspension (EAS) system. This pressure vessel (accumulator) stores a reserve of compressed air, enabling the EAS system to inflate the air springs rapidly in response to height adjustment commands without waiting for the compressor to build pressure from ambient. The reservoir reduces compressor duty cycle and allows smooth, prompt height transitions during loading, unloading, and terrain
