Offering easy and convenient air pressure adjustment for any brand of aftermarket air spring, the WirelessOne on-board air compressor system from Air Lift is ideal for any air spring user. With the included handheld controller and NEW wireless app, inflation and deflation has never been more simple. With air spring equipped vehicles, adjusting the air pressure has been an inconvenience -- find a gas station with an air compressor, then fiddle with Schrader valves until the pressures are equalized. Air Lift looked to eliminate that hassle with WirelessOne, making every part of the process simple and fast, starting with installation. WirelessONE is a single path system, meaning that both air springs will inflate or deflate to the same pressure. The air springs are inflated and deflated by an external air compressor with either one or two Schrader valves, attached to one or two air springs. Between the included wiring harness, installation hardware and a fully illustrated instruction manual, WirelessOne will be up and running in no time. Installing the system takes only an hour, with no air line or wiring needing to be routed through the cab of the vehicle, as well as no need to tap into the ignition wire. By eliminating this necessity, Air Lift removed the need to drill into the firewall and the need to work with live wires. When installed, the system allows you to quickly and easily adjust the air pressure in the air springs to accommodate changes in the vehicle's load. With the second generation of WirelessOne , Air Lift created a mobile app for both iOS and Android devices, on top of the included wireless controller, allowing you to connect with the Bluetooth -enabled manifold easily. As the leader in air suspension products for over 65 years, Air Lift is committed to delivering quality parts that last. To ensure the highest quality, longevity, and customer satisfaction, the system comes with a two-year warranty and a 60-day, no-questions-asked,
