Detailed Description

The Arnott P-4342 air suspension compressor is engineered for 2014-2022 Ram 2500 and 2014-2022 Ram 3500 trucks with factory air suspension. It replaces the original OE compressor and is supplied as a new compressor assembly kit with an integrated dryer and relay. The direct replacement design supports a straightforward service process when the factory unit has failed or is no longer keeping up with system demand. This part cross-references Ram OE numbers 68239571AA and 68349607AA for the same application.

Common causes of compressor failure include leaks elsewhere in the air suspension system, especially worn rubber air springs that force the compressor to run excessively. If your Ram 2500 or Ram 3500 is showing slow lift, repeated compressor cycling, or inability to maintain ride height, P-4342 addresses the compressor side of the repair.

What It Helps Fix

• Slow or weak air suspension inflation
• Compressor running too often or for too long
• Loss of ride height after parking
• Air suspension warning lights related to compressor performance
• Failure to build or hold system pressure

Installation Notes and Tips

Verify the vehicle’s OE compressor part number and air suspension configuration before installation. Inspect the air springs, lines, and fittings for leaks before replacing the compressor, since an unresolved leak can shorten the life of the new unit. The included electrical connectors support plug-and-play installation, but the mounting bracket and mounting hardware are not listed as included.
