Low air pressure is the main cause of air spring failure, and this system prevents that before it happens. The Air Lift Load Controller II senses when pressure drops below your set minimum—typically 5 psi, adjustable up to 10 psi—and restores it automatically. That means your helper springs always stay above the safe zone, giving you longer spring life and consistent support whether you’re hauling or just cruising unloaded.
For light to medium-duty use and occasional towing, the single-path setup makes things straightforward. A single in-cab analog gauge lets you monitor and adjust one pair of springs together. Both airbags share the same pressure, so your ride stays level front-to-back without worrying about uneven side-to-side adjustments. When your load changes, a quick tap on the switch brings everything back to balance.
Some compressors rattle or buzz when they kick on—this one doesn’t. The Load Controller II runs with high-volume airflow that’s nearly vibration-free, so you just see the gauge move without hearing much noise. You get smooth, reliable inflation every time without the constant hum in the background.
No hunting for extra parts to get started. The kit includes the wiring harness and fittings needed for a straightforward install. Once mounted, the compressor’s automatic sensor and single-path controller take care of the rest—keeping your air springs right where they should be without constant manual checks.
With a compressor duty cycle of 4 minutes on and 5 minutes off, it’s made for typical towing and hauling routines. The Load Controller II works with any brand of air springs, so you can count on it to deliver stable pressure maintenance across different setups. It’s a light-duty system that handles the work quietly, keeps your suspension healthy, and makes day-to-day adjustments simple.

After a year, not a single complaint. No worries of the pressure ping too low for typical driving, as it automatically adjusts to the minimum. On longer hauls with a lot of trailer tongue weight, manual adjusting is a breeze with the press and hold rocker switch.
