Ksport CHD421-AEX Airtech Executive Complete Air Suspension System with Auto Leveling and OLED Remote

The Ksport Airtech Executive Air Suspension System (CHD421-AEX) is Ksport's top-of-the-line complete air suspension kit, building on the Pro Plus platform by adding four corner-mounted height sensors for fully automatic ride height leveling. No switches or traditional gauges are required — the entire system is controlled through a single full-color OLED remote that displays real-time air tank pressure and individual air bag pressures at all four corners.

Automatic Leveling & Smart Control

• Four height sensors continuously monitor each corner of the vehicle and automatically adjust ride height while driving, maintaining a level stance regardless of passenger or cargo load
• Full-color OLED remote displays tank pressure and front/rear left/right air bag pressure at a glance
• Four independent user presets allow quick on-the-fly ride height changes
• 4-way adjustability — front, rear, left, and right corners can all be set independently
• Engine start memory function automatically restores your preferred ride height on startup
• OLED remote charges via standard mini-USB; a car charger is included
• Standard 4-button backup remote control included in case of remote battery depletion

Suspension Performance

• High-quality air struts engineered to withstand daily driving and drift circuit demands
• High-performance shock absorbers match the same specification as Ksport's best-selling Kontrol Pro coilover kits, with internal valving tuned for air pressure changes
• 36-way adjustable damping allows precise fine-tuning from soft comfort to firm sport — adjusted simply by turning the included damping knob
• Adjustable lower mount enables further ride height refinement at any PSI setting
• Height adjustability range of 0–120mm / 0–200mm depending on vehicle application
• Available in sleeve-type and double-bellows-type air bags to match OEM suspension configurations

Complete System Includes

• 4 high-quality air struts
