Product Details

This Arnott NEW line compressor is engineered for the 2001-2006 Lexus LS 430 and matches the original Lexus air suspension compressor application. Part number P-3187 is supplied as a complete compressor assembly kit with the bracket and electrical connectors needed for a fast, factory-style installation. Arnott also notes that compressor failures are often caused by leaks elsewhere in the air suspension system, especially worn rubber air springs, so the system should be checked for leaks to protect compressor performance.

This part cross-references Lexus 48910-50050 for the same application.

Common Problems This Part Can Address

• Air suspension compressor not building pressure
• Compressor running too often or for extended periods
• Vehicle sitting low due to loss of air suspension pressure
• Slow suspension lift after startup
• Compressor noise or failure from system leakage

Installation Notes

Fits 2001-2006 Lexus LS430, N/A. Verify the air suspension system for leaks before installing the new compressor. A leaking air spring or other system fault can shorten compressor life and reduce performance. Use the factory-style electrical connections and mounting points for a direct replacement installation.
