Aerosus offers brand new air suspension compressor for the Infiniti QX56 (2010-2013), which replace the original compressor of your vehicle. The new high-performance compressors has a compact, modular design while also providing you with maximum security and functionality. The compressor relay should be replaced before installation of the compressor unit, as failure to do so will void the product’s warranty. When the compressor is installed, Aerosus recommends you to check the complete air suspension system for any leakage. The most common cause of compressor failure is a leak in the air suspension system, most likely in one of the air springs. Leaky air springs should be replaced immediately to maintain optimum compressor performance. All our compressor units are covered by a 2-year warranty with 30-day money-back guarantee.
