Detailed Description

Arnott P-3194 is engineered as a direct OE-style replacement for the factory air suspension compressor used on the Lexus RX 450h and RX350. The compressor assembly is new and produced by the same manufacturer as the original compressor, helping maintain original system operation and fitment. Its integrated dryer and electrical connectors support a straightforward plug-and-play installation on the correct vehicle applications.

This compressor is a practical choice for 2011-2015 Lexus RX 450h owners and 2011-2012 Lexus RX350 owners who need to restore air supply to the suspension system. Arnott P-3194 is built around the original compressor layout and is identified by Lexus interchange numbers 4891048020 and 4891048021.

  • Slow or uneven air suspension height changes
