Home \ Products \ Suspensions \ AiROCK AiROCK™ is a computer controlled coil replacement system. The coil springs are replaced by our custom air springs, and the bump stops are moved to the custom shock absorbers that come with the kit. The system includes four air springs, four shocks, the user interface, the AiROCK™ Control Unit (ACU), four height sensors, stainless steel brackets, and the wiring harness and tubing to connect all of the components.   AiROCK™ ties into the Vehicle Speed Sensor, (VSS) which in conjunction with the ACU, allows the system to know the vehicle speed and height of all four corners at all times. This information allows AiROCK™ to operate in three different driving modes, which include "Off road", "Highway" and "Freeway". The end result is the best of both worlds-- total control of your vehicle's behavior off road, and a safe, level vehicle at higher speeds.         AiROCK, Light Blades, X-Line, V-Line, X-Track, X-Rings, X-Straps, U-Turn, LiteDOTs, and RockLOX are trademarks of Off Road Only, LLC.   copyright 1999-2006 Off Road Only, LLC.
