Maintaining the pneumatic leveling system is essential for the stability of heavy commercial vehicles. This repair kit provides the necessary components to restore height adjustment valves to their optimal operating condition, ensuring the air suspension responds correctly to load changes.

Vehicle and system compatibility

Installation and maintenance guidance

When performing maintenance, always depressurize the system first to prevent injury from escaping air pressure. It is highly recommended to mark the existing arm angle before disassembly to ensure the valve is reset to the same reference point during installation. Clean all surfaces thoroughly to ensure seals seat correctly without leaks.

Troubleshooting and selection

To ensure a successful repair, verify that the kit components match the dimensions of the original parts. An incorrect seal or O-ring diameter can lead to air leaks. Always check the trailer height both empty and loaded after installation to confirm correct operation.
