Arnott's air suspension compressor P-3192 for the 2003-2009 Toyota 4Runner and Lexus GX 470 is a 100% direct replacement for the original OE compressor from Toyota. This genuine Toyota Air Suspension Compressor is new and is produced by the same manufacturer as the original compressor. The compressor comes complete with a mounting bracket, electrical connectors and relay for a fast plug and play installation. This compressor is backed by Arnott's Limited Lifetime Warranty which is superior to the manufacturer's 12 month 12,000 mile warranty. The most common cause of compressor failure is a leak in the air suspension system such as the rubber air springs. Arnott recommends that you check the vehicle¿¿¿s air suspension system for any leaks to maintain your warranty and for optimum compressor performance.
