2600 030 310 Compressor Unloader Kit for Heavy Vehicles

A compressor unloader kit is a specialized component set used to maintain the pneumatic regulation of an air brake compressor. By ensuring the compressor can release excess pressure, this kit helps stabilize the air pressure output within the braking system, preventing over-pressurization and ensuring consistent performance under heavy loads.

This unloader kit is engineered to be compatible with Detroit Diesel Series 60 and S60 engines. It is frequently fitted to heavy commercial vehicles including Freightliner models such as the Cascadia, Columbia, and Coronado, as well as Kenworth T800, T600, and W900 trucks. Other compatible applications include Western Star 4900, Sterling LT9500, International 9400, and Peterbilt 378/379 units.

For professional workshop technicians, installing a high-strength unloader kit is a critical maintenance step when diagnosing pressure regulation issues or air leaks within the compressor assembly. Regular inspection of these components helps prevent system-wide pneumatic failures in heavy-duty transport fleets.
