Exclusive non-contact Magnetic Height Sensor

Our exclusive OEM-quality height sensor uses non-contact magnetic technology to maintain your vehicle’s ride height. This reduces the possibility of malfunction due to dirt or other road debris interfering with a contact arm.

Single or Dual Path Models

SmartAir II is available in single or dual path models. Dual path allows for the inflation of each air spring independently to different pressures depending on load, while single path allows for the inflation of both air springs at the same rate at the same time.


With our 60-day no questions asked, money-back guarantee, we’re convinced you’ll be happy with the improvement in ride comfort, load handling and air spring control. If you’re not satisfied, remove the compressor system and return to your dealer within 60 days for a full refund of your purchase price (excluding installation or shipping charges).

All of Air Lift load support on-board air compressor systems include a two year warranty. We warrant that your system will be free from defects in workmanship or materials for two years on the vehicle of original installation.
