Show original supplier description
The Ksport Airtech Executive Air Suspension System CNS390-AEX offers a sophisticated approach to vehicle suspension, designed for the 2009-2014 Nissan Maxima A35. This kit provides an extensive range of adjustability, including 36 levels of damping adjustment for precise control over ride stiffness and comfort. The height adjustability is substantial, with a range of 0–120mm for the front and 0–200mm for the rear, enabling users to achieve their desired ride height and stance. The Executive system integrates four height sensors that automatically monitor and level the ride height while driving, eliminating the need for manual switches or gauges. Operation is managed through a single OLED color screen remote control, which displays air tank pressure and individual corner air bag pressure. This remote also allows for saving up to four user presets for quick ride height changes. The system offers independent 4-way adjustability for each corner. The system includes VIAIR compressors (a single Viair 444c is standard, with an option for a second), a polished 5-gallon air tank, all necessary hoses, wiring, and installation manuals. A standard 4-button remote is included as a backup. The system can raise the vehicle from its lowest setting to maximum height in approximately 2-5 seconds. Professional installation is recommended.
