Ksport CHD121-APP Pressure-Based Air Suspension System with OLED Remote Ride Height Leveling

The Ksport CHD121-APP Airtech Pro Plus is a complete, bolt-on air suspension system featuring four-wheel independent ride height adjustment and pressure-based automatic leveling — all controlled from a single OLED color screen remote. No switches, gauges, or complex wiring are required, making this one of the most user-friendly full air suspension kits available.

The full-color OLED remote displays real-time air tank pressure and individual air bag pressure at all four corners. Store up to four user presets for instant ride height changes on the fly, and take advantage of the automatic engine-start memory function to restore your preferred ride height every time you start the vehicle. The remote charges via standard mini-USB, and a car charger is included. A standard 4-button backup remote is also included in case the OLED remote battery is depleted.

Key Features:

• Pressure-based auto-leveling while driving — height sensors can be added later for sensor-based leveling
• VIAIR 444C compressor raises the vehicle from lowest to maximum height in as little as 2 seconds (optional second compressor available)
• Polished lightweight 5-gallon air tank for ample air volume and fast response
• Ksport seamless installation control box included as standard
• 36 levels of damping adjustment for precise ride and handling tuning
• Adjustable lower mount with 0–120mm / 0–200mm height range (vehicle dependent)
• High-quality air bags engineered for daily driving and drift circuit use
• Bolt-on installation — no modifications to OEM shock absorbers or OEM top mounts required
• Vehicle may require modification for air-line routing
• All hoses, fittings, wiring, and installation manuals included

The Ksport Airtech Pro Plus builds on the Deluxe kit by adding four-wheel independent height control and the advanced OLED remote interface. Whether you're cruising daily or pushing limits on the track, this system delivers near-infinite adjustability with a clean, professional install. Professional installation is recommended.
