The e-Level Controller offers the ability to save three unique heights into memory at the touch of a button using TruPosition height sensors installed in each corner of your suspensioin. The key to this technology is its RideMonitor Mode; while parked or driving, the system will maintain the vehicle height when loading or unloading passengers or when road conditions change. All of this automatic intelligence is unnoticed by the driver, providing improved ride quality and handling characteristics for any vehicle with Air Suspension. The adjustments made by an e-Level Controller are so accurate that each will maintains its height within 1/8th of an inch and prevents "cross-loading" of AirSprings at a higher accuracy than any other method. Each system calibrates to the vehicle upon installation and then learns how your Air Suspension behaves over time. This flexibility allows the e-Level Controller to be used on ANY vehicle and requires NO user tuning. For the ultimate in form and function, the intuitive TouchPad is the top-of-the-line interface option for the e-Level Controller. Available in black-anodized or nickel-plated aluminum, the TouchPade gives full manual controll over each Air Spring individually, as well as front and rear in "pairs". Saving and accessing your three preset heights is only a touch away and a yellow glowing ring around each button clearly indicates the current vehicle height. Every button is backlit with crystal white LEDs for clear daytime and nightime operation and an "All-Down" button fully deflates the vehicle for parking.
