Ksport CHD390-APP Airtech Pro Plus Complete Air Suspension System with OLED Remote

The Ksport Airtech Pro Plus (CHD390-APP) is a complete, pressure-based air suspension system featuring four-wheel independent ride height adjustment and an intuitive OLED color screen remote control. No switches, gauges, or complex wiring are required — all ride height management is handled through the wireless remote, keeping the installation clean and straightforward.

The full-color OLED remote displays real-time air tank pressure as well as individual air bag pressure at all four corners, giving you complete visibility into your system at a glance. Four programmable user presets allow instant access to your favorite ride height configurations, and an engine-start memory function automatically returns the vehicle to your preferred height every time you start the car. A backup 4-button standard remote is also included in case the OLED remote needs charging. The remote charges via standard mini USB, and a car charger is included for added convenience.

At the heart of the system is Ksport's seamless installation control box paired with a Viair 444C compressor, capable of raising the vehicle from its lowest setting to maximum height in as little as 2 seconds. A second compressor can be added at an additional cost. The kit also includes a polished lightweight 5-gallon air tank — a notable upgrade over the Basic and Deluxe kits — along with the pressure-based automatic leveling system that continuously monitors and adjusts air spring pressure while driving to keep the vehicle level. Height sensors are not included but can be added later for true ride-height-based leveling.
