How do I use my scale?
In order to get an accurate weight with your onboard scale, park your vehicle on level ground with the engine running and the brakes released. Briefly deflate the air suspension and inflate to ride height. Weights are displayed on the easy-to-read digital display.

How does my scale work?

LoadMaxx works on tractors with air drive suspensions and most trucks with leaf spring steer axles and air suspension drive axles. Air sensors measure pressure in the air bags, and deflection sensors measure flex for axles with leaf spring suspensions. The scale converts the sensor measurements into accurate on-the-ground weights.

When properly calibrated and used, LoadMaxx is accurate to within 300 lbs on each axle group.
