For drivers of light- to medium-duty vehicles, LoadController provides the maximum convenience, for leveling on-the-go. LoadController offers convenient and easy adjustability of your air spring pressures, based on changes in load weight and road conditions. With an exclusive low pressure sensor that automatically activates if pressure drops to an unsafe level, you can be sure that your vehicle and load are protected, no matter what the road throws at you. With an in-cab gauge control panel, you can inflate your air springs at just the touch of a button. The easy-to-read pressure gauge allows for on-the-go adjustments, with one gauge, dual needles, and a simple inflate and deflate button. LoadController (Panel, Dual Path, Heavy Duty) is a dual-path system, meaning that the air springs can be independently adjusted to different pressures, perfect for uneven loads. Dual path systems help to prevent air transfer between air springs, which provides a more stable cornering situation and significantly less body roll.
