Zongzhu's remanufactured Air Compressors are completely restored to the factory’s Original Equipment specifications, as an exact replacement for the compressor in your air suspension. Our remanufacturing process replaces all of the wearable components, after the core has been inspected and cleaned thoroughly for any deterioration or impairment, guaranteeing it still meets the manufacturer design. The seals and dryer are completely replaced, and all electrical connectors are tested to ensure they still function as intended. Air Compressors in your suspension provide air to the springs, shocks or struts, supporting your vehicle’s weight and adding support when needed.
