Official summary

Air Suspension Components Star Parts Catalog has been updated to show individual service parts for the compressor assembly. This will allow service technicians to repair the root cause without over repairing the system. Replace only the part deemed failed by the diagnostics performed. Individual parts include: - Compressor - Valve block - Individual hoses - Temp sensor - Shield - Air line clips NOTE: in most situations when a new compressor is needed, the compressor as a separate part is the correct repair, and the assembly would not be required.

Vehicles covered

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
