Ksport CHD440-APP Pressure-Based Air Suspension System with OLED Remote Independent Ride Height Control

The Ksport CHD440-APP Pro Plus Air Suspension System delivers the ultimate in ride height control and daily-drive versatility. Building on the Deluxe kit, the Pro Plus adds four-wheel independent ride height adjustment, giving drivers unmatched precision over their stance — all without traditional switches, gauges, or complex wiring.

At the heart of the system is a full-color OLED remote control that displays real-time air tank pressure and individual air bag pressure at all four corners. Four user-programmable presets allow instant ride height changes on the fly, while the automatic engine-start memory feature sets your preferred ride height every time you turn the key. A standard 4-button backup remote is also included for convenience.
