Old fashioned automatic level systems used a lever between the frame and the axle to determine level and ride height. The levers were hard to mount and calibrate and prone to failure. Now Air Lift solves the problem with SmartAir, an exclusive electronic system that has no contact arm! It’s quick and easy to install and has no lines at all to the cab!
The leveling system senses when the system is not level – either too low or too high – and automatically returns to the desired set ride height. Works under any road or load conditions… it simply keeps the vehicle level, no matter what!
