It automatically maintains proper chassis height by adding or exhausting air from the air springs as load changes, ensuring consistent handling and tire wear. An integrated dump valve lets you quickly deflate the air bags for uncoupling a trailer or performing suspension service. It’s commonly used on Peterbilt and Kenworth trucks, but also fits many other air-ride suspensions. The '-PS' suffix appears to be a dealer-specific packaging or inventory variant of the standard HV9990.
