AccuairElectronic Leveling SystemFrom its earliest days seeing usage on heavy-duty commercial semi-rigs, air-ride suspension found its beginnings in the big-truck arena as a no-frills utility. The idea of using air-ride suspension systems strictly as an aesthetic device to drop a vehicle as low as possible when parked, and then be able to lift and drive away first appeared on radically customized mini-trucks. Although rudimentary light-duty truck air-ride setups showed potential for a slammed stationary stance while paired with the ability to achieve a reasonable ride height there were some serious operational and reliability issues. Amongst the flaws was severely uneven front tire wear attributed to erratic manually set ride heights affecting camber angles and caster alignment. In 2001, during the early stages of air-ride's popularity, two young brothers, while one was still in high-school and the other studying to be an engineer in college decided they would dedicate their efforts to focusing on producing a computerized air-ride management system that would be compatible with every manufacturer's air-ride suspension. What Reno and Dustin Heon didn't know when they opened the doors to AccuAir was beyond the customized early C10 Chevrolet trucks, their new system would find a much larger market on commercial applications that demanded a serious ability to function with a repeatability that could be guaranteed. A good example is on ambulances where as soon as the vehicle comes to screeching halt and the rear doors are opened it automatically drops (kneels) to the ground, and eases loading of a gurney. On departure, as soon as the ambulance drivers slam the rear doors, the vehicle triggers to ride height before it's in gear and accelerates away. Once the ambulance is underway the next immediate task is to monitor ride height, and prevent cross-jacking caused by trying to maneuver a heavy vehicle through curves, straights, and road irregularities. What all of this means to the owner of a customized classic truck is when they want to use their truck for pleasure the experience won't be ruined by a primitive, out of date air-ride setup that can't monitor leakage, or low-voltage situations, and let the owner know before it's too late. Couple this with improved handling characteristics and the wind gets knocked right out of just about any argument against installing an air-ride suspension setup.
